Re: [Mono-dev] Problem in SvcHttpHandler.cs ?
The reason why there are no synchronous calls in silverlight is (I
believe) because you can easily deadlock the plugin by attempting a
synchronous call when using the browser http stack. For the web
request to be completed, the browser has to be able to iterate and if
a plugin is blocking, there's nothing the browser can do.
If I remeber correctly there is an explanation of this on msdn
somewhere.

Right now we have no plan to build mono specific WCF libraries. IMO
libraries like
what you said should be released cross platform, at places like
codeplex.
Instead you might have some useful code that could be used in our own
core WCF
assemblies (imagine if you have implemented WS-AtomicTransaction aside
TransactionFlowBindingElement, and we don't have working code now.)

Hi Atsushi,
I have started messing with WCF last week but I'm very interested in
learning, If you need help with anything just send me a message.
Also, today I'm starting to develop an http binding/channel to allow
REST syncronous programming of WCF Services/Clients(compatible with
moonlight/silverlight 2/3). I know syncronous service calls aren't
officially supported by Silverlight, but(correct me if I'm wrong) I
don't see why that should'nt work if I extend at channel level. If

Hi,
Right, thanks for the analysis, that should be fixed, and I have
an idea.
Though I am now rewriting ASP.NET channel support based on our new
HTTP
(non-ASP.NET) channel stack and it does not use the code path you
mentioned,
I'd rather finish the rewrite first and then fix the actual issue.
The idea above is to use Uri comparison using UriComponents based on
HostNameComparisonMode value (which is ignored so far).

The service works well if I access it on the local machine using
the
http://127.0.0.1:8080/Person.svc; Url, but fails with the same
error
if I use http://localhost:8080/Person.svc;. After looking into the
source code I think the problem may be on the following
conditionals
(method 'FindBestMatchListener') :
if (l.Uri.Equals (ctx.Request.Url)) {
best = l;
break;
}
//
if (!ctx.Request.Url.ToString ().StartsWith (l.Uri.ToString (),
StringComparison.Ordinal))
continue;
Maybe it should check the Uris for all the network interfaces?(I
have
no idea on how to do that).

Re: [Mono-dev] Compiler bug in foreach
Hey,
I filed a bug and then realised you had already filed it. I marked
mine as a duplicate of yours and changed the severity of yours to a
more appropriate level. Generally speaking we reserve 'critical' for
bugs which affect a large proportion of applications ( 50%) and cause
major issues or security holes in those applications.
Thanks for filing the bug and hopefully it'll get sorted soon. If you
need a workaround *right now* then the easiest thing to do would be to
compile using the microsoft compiler and then run the resulting
assembly under mono. This is purely a compile time bug.

Re: [Mono-dev] System.NotImplementedException: The requestedfeature is not implemented. atSystem.ServiceModel.Configuration.WSHttpBindingElement.OnApplyConfiguration
I am thinking of a Java/.NET split if you will where we keep what we can that WILL run under Mono and port the rest to Java. That assumes we can get the two to play nicely together. Depending on what it is that doesn't work, it's possible that it'd only take you a couple of days could fix your issue. That'd be significantly less time than porting to java.

First, ExclusiveAddressUse was optional and not my real problem anyway. Skipping it was perfectly fine. The real problem was that I normally bind a different socket to each local interface and join the SSDP multicast group. After much trial and error I noticed that if I bind to ANY, it worked and I started receiving multicast traffic, but bind to a specific interface and I would not. Now, I MUST know the specific local interface on which I received the multicast packet so, binding to ANY is not an option. I then noticed that you can specify an interface in the multicast join, so I tried creating a bunch of sockets all with ANY bind, but each with a multicast join on a separate local interface. That worked! I had to chance the code because normally when I receive traffic, I look at the client.localendpoint to give me to local interface then traffic came on. Since all sockets are now bind to ANY, I have to carry the localendpoint separately. This was an easy fix and the result is impressive. The main tools Device Sniffer, Device Spy and Network Light all work perfectly.

Re: [Mono-dev] [PATCH] - optimization for System.Xml.XmlNode::SelectSingleNode
Why would a c-cast be so much slower than an 'as' cast? Surely they should be equivalent or the c-cast should be faster. Alan.

Re: [Mono-list] Has Anyone Read UDP Data with Mono?
How are you running the program? Do you have two different machines and are trying to send between them or is it the same machine used as the sender and receiver? It sounds like the case that doesn't work for you is sending data between two different machines, in that case it really does sound like a firewall issue. Maybe the app you're using to sniff the packets is checking the data before your firewall app applies its rules to it. Alan.

You've misunderstood what I've said I think :) No matter what you do you will always require either 1 or 2 .config files and 1 binary. Lets take the typical example where the only reason for the .config is to do dll remapping. In this (the most common) case, you will mark all your P/Invokes with the windows binary name and distribute your binary with no dllmap for windows based platforms. If you want this binary to run unchanged on non-windows platforms (maxos, linux) then all you have to do is ship the exact same binary with a .config file containing the dllmaps. You do not require a separate binary. So in this scenario you need 1 binary and 1 .config file. For the more complex case where your app has an existing .config file which it requires on windows, you'll need two .config files. The windows one will not contain the dllmap entries and the non-windows one will. You still need only 1 binary in this case. Alan.

Re: [Mono-dev] Socket.BeginReceive never throw Exception
Hey,
It really does look like a valid issue but as it stands there's no
testcase to reproduce the issue. I do this *all* the time in the
testcases for MonoTorrent and my callbacks are always invoked. I
explicitly test for this in some of my testcases. There are times when
EndReceive is not supposed to throw an exception even though the
socket is not connected. Maybe you're hitting this case. It's just
impossible for me to see this bug happening so it's impossible for us
to fix it.
I'm not asking you to defend your bug report, i'm just asking you to
make it easy for us to fix it. You have a testcase which can reproduce
the bug 100% of the time. If that testcase could be supplied as part
of the bug report, it would be so much easier to resolve the issue.
All you need to do is put the testcase in a console app so that we can
just compile and run it to see the issue.
Thanks,

the behaviour from both frameworks deviate. I think my original message

property being set to false works with Mono and isn't needed for Microsoft's
.NET (as the event properly fires). Sockets are set into NoDelay,
NonBlocking mode and then use asynchronous calls with BeginReceive and
EndReceive. Maybe it is that particular constellation, or maybe the g++
compiler, or maybe the host system.

I know, this is not the most recent version ATM, but the OP replied that
this behaviour occurs with 2.6.3 as well and I do trust their judgement.
I've never gotten into the notion on having to defend my bug reports. I do
my own test cases and testing, but you are welcome to put it down as a bug
in my code. As I only need Mono for a quick internal use case in two weeks'
time, I'll get away using a workaround. Good luck getting this fixed (should
you decide to treat it as a valid issue), and take care ;)

On Thu, Apr 8, 2010 at 10:25 AM, Alex Corrado alexander.corr...@gmail.com wrote: Dear Mr. de Icaza and the Mono Developer Community, First, I would like to salute you for producing an excellent, open platform for software development. Second, I would like to apologize for bothering anyone who is not interested in a student's proposal to improve it. I appreciate your time and any feedback you might give. I am proposing to expand Mono's C++ interop support to enable the creation of managed wrappers directly around native C++ objects. This would make C++ libraries callable directly from managed code without the need for wrapping them in a flat C API, COM interface, or requiring the use of mixed binaries (C++/CLI). In fact, this could also provide a way to implement the C++/CLI language, including IJW, in a cross-platform manner. The first place I read about calling C++ functions directly from managed code was on Mono's Interop with Native Libraries page. It suggested setting the EntryPoint of the DllImport attribute to the C++ mangled function name to call that function directly through P/Invoke. However, it wasn't until I read this blog post by Jim Springfield that I realized that, not only could this be a viable technique, but that by messing with virtual tables, native C++ classes could effectively be subclassed by managed code. This technique could allow for seamless managed wrappers around native C++ classes. Jim Springfield's example is tied completely to Microsoft's Visual C++ compiler, and this illustrates the largest problem with this approach: that C++ ABIs are different among different compilers and even between different versions of the same compiler. To help ameliorate this issue, I have taken the basic principles in Springfield's design and abstracted out any ABI-specific components into an abstract class. A different subclass of this CppAbi class can then be implemented to support each compiler's different name mangling schemes and other idiosyncrasies. At runtime, the correct CppAbi instance can be chosen when loading the C++ library depending on platform or other conditions. Reflection.Emit is then used to generate the P/Invoke code and implement trampolines to facilitate virtual method calls. Eventually I hope to support seamless exception handling and other features supported by C++/CLI on Windows. I realize this sounds very ambitious, but I've already implemented a proof-of-concept based on a simple C++ class, similar to the one Jim Springfield uses in his example. It is hosted on Google code at http://code.google.com/p/cppinterop/. Please note that this really is just a proof-of-concept-- I've only implemented the Itanium C++ ABI, and only in part. If you are using a recent version of GCC to compile C++, you should be able to compile the example and call it directly from managed code. I've only tested this on an Intel Mac running OS X 10.4.11. I would include some details about myself, but I feel like this email is already long enough. So if there is anything in particular you would like to know, or any feedback you might have, please feel free to contact me. Thank you very much for your time.

Re: [Mono-list] Wrapping a native library which uses unsigned long on 32 bit and 64 bit systems
Unfortunately there's no trivial way to map this. If you follow that rule, you're broken on 64bit windows systems (if you care about cross platform compatibility). There may be other systems which won't work with that rule, but I don't know. One approach is to create a wrapper C library which you P/Invoke instead of P/Invoking the actual library you want to use. The wrapper library can expose exactly the same API, but it can change usages of 'long' to either int32_t or int64_t as appropriate so that other languages (not just .NET ones) can easily call those functions. If you don't want to do that, there's really very little - if anything - you can do other than guess and write multiple P/Invokes for each case. For example you could write two p/invoke signatues, one which maps a C long to a .NET int and one which maps it to a .NET long. Then at runtime you can detect what platform you're on and whether it's 64bit or 32bit and then make a guess as to which function will not blow up when you call it. This isn't a great approach unless you're positive you know all the platforms you're going to run on ;) Alan. On Thu, Mar 25, 2010 at 9:17 AM, Mathias Tausig mathias.tau...@a-cert.at wrote: Hello!

If you had been in Brussels for FOSDEM over the last few days you would've had a completely different mono experience. Not only were plenty of folks involved with mono there (from programmers to packagers to users), but there was a room dedicated to mono and mono related presentations. It was quite unlucky the power line broke, but if you're interested in seeing some of the mono related talks that were recorded at FOSDEM they shoul be available on the FOSDEM site over the next couple of days.

If someone has domain knowledge and implementation skills on top of CLR but can show that Mono is defective, its efinitely reasonable to ask them to give 'the mono development community' a test case and bug report. But expecting them to climb the mountain of learning to fiddle with a particular CLR implementation's core is nuts, particularly when they have an alternate that works for them to do their day job. If someone wanted to climb that mountain and make the changes, then presumably they would want to start by reading the copious up to date detailed design documentation and implementation notes on how (and why) it works now, so that they could size the task. Oh wait ... :-( Its much, much more efficient for someone who already groks the internals to make fiddly low-level changes, particularly if getting them into the release stream requires a lot of trust relationship with the release masters. I think you do a huge disservice to everyone by trying to get outsiders to work on something like that - or perhaps you just want people with bad news to go away so you can paper over the cracks? Please, ask for test cases and reports. FWIW I suspect (justa hunch, I'm certainly not an expert) from what's been said that if a calling convention change is needed (and I seem to remember there are some issues that prevent fuller use of LLVM that one might also want to consider if that sort of change is on the cards) then its as much a political and major-version-compatibility issue as it is technical, and once again asking someone to work on patches in such a situation is laughable, given the degree of risk that they might completely waste their time.

Re: [Mono-list] mono performance, 20x differential with Java (what am i doing wrong)
If you mean you want the SIMD extensions to be part of the .NET 5.0+ specification, then that may be an option in the future should someone decide that it's worth all the paperwork and time involved. As it stands, Mono is the only VM (that I know of) that allows you access the various SIMD instruction sets available on modern CPUs. While GPU accellerated code may be possible in the future, that would have to built on top of whatever API the GPU exposes (CUDA or whatever). That would be completely separate to Mono.SIMD as this just exposes additional CPU instruction sets to .NET languages. Alan.

Re: [Mono-list] Mono 2.6 for Ubuntu
If the ubuntu devs are happy with installing one giant tarball as supplied my Novell, then it's amazingly simple to supply them with new packages every time Novell releases a new version of Mono. However, they are not happy. They have their own strict packaging guidelines and do a lot of extra work splitting the standard install into dozens of small individual packages. This is one of the reasons why Ubuntu/Debian lags behind. It's not up to Novell, or any project, to create packages for every distro under the sun (whether it be the most popular distro or least popular distro) when each distro has its own specific packaging policies which essentially means one unique package will have to be created using different rules for every distro. If you wish to employ someone to do that, feel free. Your examples with Chrome and gnome do aren't quite the same as mono though. Mono is a core framework. Changing that will affect multiple applications and can (potentially) cause things to stop working in strange and unusual ways if an application relies on a bug which was fixed.

Re: [Mono-list] Mono 2.6 for Ubuntu
Hey, I may have phrased that last email slightly incorrectly. My point was that debian/ubuntu is slower than opensuse because they require multiple changes to the released tarball to generate their packages. Opensuse does not require these changes so opensuse is faster and easier to make releases for. I wasn't trying to imply that novell can and will start creating a generic installer which can be used on any system, nor was I implying that novell would consider creating their own PPA and releasing up to date mono packages for debian/ubuntu. There was a time when there was a generic mono installer which worked for all linux distros. The problem is that people would frequently corrupt their system mono by using that generic installer and found it very hard to fix things later. A similar issue would happen if Novell tried to make a generic mono package for ubuntu/debian using a PPA. Unless the generic package was completely synced with the standard system package, you could easily end up corrupting your install by having libraries from two different mono versions. If you really really want up to date unstable packages for $INSERT_DISTRO_HERE, then you'll have to either motivate someone to create them or try to do it yourself. Alan.

That should really be: if m_buffer.Length == 0 as the case where the Length

Re: [Mono-dev] Why not build official site on ASP.NET? Mono should enhance server performance and stability!
Hey, MonoTorrent uses the standard .NET threadpool for all asynchronous sockets. It's all standard Socket.BeginReceive/Socket.EndReceive calls. I've run it with ~150 open connections in the past with no issues, though it's worth noting that 150 open connections != 150 actively transferring connections. If you're seeing issues with running out of threads and connections being dropped as a result, just export MONO_THREADS_PER_CPU=100 to increase the maximum number of allowed threads and see if that helps. Feel free to vary the number up or down as appropriate. Alan.

Re: [Mono-dev] Why not build official site on ASP.NET? Mono should enhance server performance and stability!
Just to add, while MonoTorrent doesn't use it's on threadpool, it doesn't hog ThreadPool threads by blocking inside the async callbacks. As soon as a message is received and my callback is invoked, I queue the message to be processed and allow thread to return to the ThreadPool. As such, even with a large number of actively transferring connections ( 50) I only need a handful of threadpool threads. If you starve the threadpool, your performance will suffer accordingly ;) Alan.

Re: [Mono-dev] Problem with PackagePart URI containing spaces
You want to file it under Mono: Class Libaries product. Unfortunately
there's no component for the WindowsBase dll, so for the moment just use
'System'. I'm going to get in touch with our bugzilla guy and try to get a
WindowsBase component put up there. If you are filing bugs, do look out for
it as it should be there within a day or so.
Thanks,
Alan.
p.s. You forgot to hit 'reply-all' with your last email. I've added the
mailing list back into the CC but just look out for that in future.

Re: [Mono-dev] Should we replace MemoryStream?

Probably stupid question: why is a compacting garbage collector actually needed? C programs have survived for a *long* time without any ability whatsoever to compact memory, simply by carefully optimizing their allocation algorithms to avoid fragmentation. Is the mono allocator very non-optimal in this respect? One of the causes is that in a garbage collected language you allocate when you need something and discard it when you're done. If you do this with large buffers which are pinned in memory and have just the wrong allocation pattern, you can bloat your memory usage. There's nothing mono can do in this case as essentially it's the user causing the bloat. One thing you can do is keep a cache of buffers yourself and re-use them. For example if your application allocates 10 chunked memory streams a second and Dispose () them when you're done, you could add/remove the 'chunks' from a cache. This way you'd only ever allocate 10xsizeof (chunked stream) bytes of memory and you'd constantly re-use them. Alan. Like I said, I feel like this is a stupid question. But I'm curious about the answer, and neither your blog post nor the linked page on the sgen collector addresses it.

Re: [Mono-dev] faster than hashtable?
If the key is random, a hashtable is the fastest way. You may be able to eke some extra speed out of the DictionaryK, V class by ripping all the code to support generic keys and instead hardcode the key to always be a long. That should save a bit of time, though whether it'd be noticable or not I don't know. Alan.

Re: [Mono-dev] Big performance gaps between .NET, Mono (Suse/Debian) ?
Calling 'ToString' is just a GC benchmark. Yes, the current mono GC is slower than the .NET GC in this scenario. Your other tests also do a fair bit of allocating, so it's quite possible the entire performance loss you're seeing is just from the GC kicking in.

Re: [Mono-dev] 2.6 preview 1

I've been having a tough time getting any kind of performance out of my threads on the Mac+Mono platform. Maybe this is the solution? Unlikely. I mean this in a constructive way, but the problem is more likely just a bad threading implementation. Altering how you split data up between threads and/or how you manage the threads would likely be the best way of improving performance. Performance of Mac + Mono should be very close to Linux + Mono. If you're seeing a huge difference in the exact same code it might be worth filing a bug.

Re: [Mono-dev] .NET / Mono runtime multi-cast differences.
Hi,
Unless I'm missing something, you haven't actually described what the
problem is. Nor have you mentioned what exactly happens on windows, what
happens on linux and what you actually expected to happen. Your example also
appears to be missing information which might help figure out what issue it
is you're seeing, what are listenChannel and listenEndpoint?

I have observed a difference in behavior between the Mono runtime and

Unless the Socket.Bind operation is modified to bind to a different end
point based on the runtime, no packets will be received. The workaround
that I am using is shown in the attached code section.
I took a look at Mono's source code. Additionally, I wrote a short C
program with the equivalent functionality. The C version for Linux
exhibits the same behavior. It is my impression that the behavior is due
to differences between the Windows socket implementation and the Linux
socket implementation. It is also my impression that these differences
are being realized by both the .NET and Mono runtime which ultimately
consume them.
I have 2 questions.
1) Am I wrong? Is there a runtime agnostic way to do this? (Binding to
IPAddress.Any does not work on Windows to my knowledge)
2) If I am not wrong, what steps, if any, should be taken to resolve
these differences?
Thanks

Re: [Mono-list] how to resolve kernel32 error from mono
Put simply, you need to rewrite every section of code that uses [DllImport]
so that you don't call native functions on non-windows platforms. This is
not a mono bug as such, it's just your application is assuming that windows
specific features are going to be available on linux/macos and they aren't.

I'm not sure what you mean here. Mono should be API compatible with MS .NET. Also, doesn't the mono compiler and runtime have a different GAC. Wouldn't compiling against the mono compiler ensure that all the methods in the standard assemblies exist in the mono version? Sure, compiling under mono would ensure that you are not using a method that does not exist. There are other tools which can help with that, such as Moma (http://mono-project.com/MoMA). Sure, you can compile under mono, but it's not a necessity. Rregularly running your regression tests under both frameworks would be a great way to ensure everything operates as expected. Alan.

Out of interest are there any build tools that manage Mono projects in a sane manner or do they all face the same problem I've bumped into trying to use make?

If so, the solution really isn't shut up and deal with it, the solution is to realise this isn't a problem. There is a way to simulate the C build process, but it'd make your compile take at least three times longer than normal and would make maintenance of your project such a gigantic pain that you'd revert back to the normal (fast) workflow within days.

Richard Stallman: Mono is a free implementation of Microsoft's language C#. Microsoft has declared itself our enemy and we know that Microsoft is getting patents on some features of C#. So I think it's dangerous to use C#, and it may be dangerous to use Mono. There's nothing wrong with Mono. Mono is a free implementation of a language that users use. It's good to provide free implementations. We should have free implementations of every language. But, depending on it is dangerous, and we better not do that.

I'll address all of the questions in this e-mail, rather than reply multiple times. 1) I used file to determine that the .exe files were 32bit. It is entirely possible that file returns 32bit for all .exe, rather than examine the file. 2) Is there a way to store char/string data as something smaller than UTF-16? The data are SNP genotypes, i.e. a single SNP genotype looks like A T and there are almost a million of these per individual. I'm thinking that what I need to do is record the genotype as bits, i.e. 0 or 1, and relate that back to a translation class thet returns A or T when that SNP is queried. It would be simpler if I could store char/string data as something reasonably small. Use the BitArray class. That's exactly what it's for. If it's possible for you to store your genotype using bits as opposed to strings you'll *vastly* reduce your memory requirements. Alan. 3) What I'm currently doing is: a) read in each line as a single string which is split based upon whitespace b) input each SNP into a class which is stored in an ArrayList, or as a string array in a Liststring (I've implemented it both ways) c) once the while file is read in, output each collection of SNPs by chromosome to a different file for processing by other software I've been able to get past my initial problem by re-compiling mono with the large heap size GC and when the entire data is read in, it takes up 17GB RAM for a 300MB file.

In doing this, I can read in about 25 rows before Mono bombs out with an out of memory error. How are you reading in these lines? What I found was the mono executable was indeed 64 bit, but gmcs.exe and mcs.exe were 32 bit. As Chris Howie mentioned, these are actually in platform-neutral IL, and will be run using a 64-bit address space when using `mono`. One other point, memory usage is horrible. I admit that I'm new to C# and mono, so my coding skills are not as good as others, but a 300MB file should not use 2GB RAM to read in 1/8 of the file. That depends ~entirely on how you're reading in the file. Also keep in mind that .NET strings are UTF-16, so if your input text is ASCII, you will require twice as much RAM as the size of the file, e.g. 600MB of RAM to store the entire file as a string. (Then there is various object overhead considerations, but these are likely tiny compared to the 300MB you're looking at.) I stopped using classes to store the data and went with Liststring and Liststring[] to read in this much data. Any comments on how I might improve this performance would be appreciated. To provide any comments we'd need to know more about what you're trying to do. For example, reading a 300MB XML file using XmlDocument will require *lots* of RAM, as in addition to the UTF-16 string issue, each element, attribute, etc. will be represented as separate objects, with varying amounts of memory required. DOM would be something to avoid here, while XmlReader would be much better. The easiest question, though, is this: do you really need to keep the entire file contents in memory all at once? Or can you instead process each line independently (or while caching minimal data from one line to the next, so that the contents of previous lines don't need to be maintained). This would allow you to remove your Liststring, and save a ton of memory. - Jon ___ Mono-list maillist - Mono-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-list ___ Mono-list maillist - Mono-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-list

Consider this very simple WinForms application which executes properly in
Microsoft .NET framework but on Mono doesn't function correctly:

// Instantiate Panel control:
Panel MyPanel = new Panel();
MyPanel.BackColor = Color.Black;
MyPanel.Size = new Size(100, 100);
MyPanel.MaximumSize = MyPanel.Size; // This line appears to be
the culprit.

this.Controls.Add(MyPanel);
// Display Panel size in Title bar:

}
}

Re: [Mono-list] HashSet appears present but uslessly broken on Ubuntu

Hmm.. there may have been some confusion in the version numbers. As I stated in the previous post, the version of the _ubuntu package_ I have is 1.2.6+dfsg-6ubuntu3. The mono version is 2.0. Yes, and that version is quite old. You'll need something newer to utilise these new fancy features. Alan.

Re: [Mono-dev] Incremental build for mono compiler
Hey, The only reason I ask is that miguel pointed out that the compiler is undergoing substantial refactoring which will take 2-3 months. That would mean that the work should be complete about the end of June, 4-5 weeks from the end of gsoc. So, if you are going to go ahead with this, I'd recommend getting in touch with whoever is working on the compiler and getting their input on how best to proceed. They may have some useful advice on where to start and what major changes are going to be implemented which will affect your project. Alan.

Re: [Mono-list] HashSet appears present but uslessly broken on Ubuntu
Hey, You can try using a local copy of System.Core.dll from newer Mono. I have no experience in mixing different versions of libraries, though, so I have no idea whether it will work. I'd highly recommend *against* doing that. Mixing class libraries between mono versions is good way to get breakages. What I would recommend is using something newer than 1.2.6, that'd be the best way of making it work.

Re: [Mono-list] Mono and its limitations
Hey, In my application I often use serial ports or read/write access to files: how the code could successfully run either on Windows or Linux? They are quite different: for example Windows calls the serial ports COM but in Linux I have to look under /dev... So I can't understand how the same code could run on both systems. .Net calls them System.IO.Ports.SerialPort. That's all you need to use to guarantee yourself cross platform code ;) Alan.

Re: [Mono-list] advice for debugging threading bugs?
Hey, Just to expand on that - it's not just a mono limitation, it's also a limitation on the MS .NET framework. There are many tutorials around explaining different ways on how to solve this problem. You shouldn't have a problem finding one in google.
