I suddenly started getting this crash in code that was previously working.
I use mono 2.10.8 built from sources in ubuntu 12.04.
Unhandled Exception: System.IO.IOException: Invalid handle to path

IMO the current stable release is not suitable for softrealtime
software such as algotrading.
To no fault to C# in general, I find mono to still lack a bit in terms
of stability compared with .Net. (That dreadful native side memory
leak has hurt me quite a bit but is supposedly fixed in master)

AFAIK, on windows, they should already have .net installed and as such
most mono applications should work as is if all dependencies are
installed (ie: gtk#/gtk). On linux, if they do not have mono
installed, they will need to install it.
There is also the option of bundling mono, see

I would advise against a design relying on a crash callback to save data.
I do believe in mono (under linux only?) that you can hook into the
sigkill/sigterm or something similar. However, it probably isn't very
safe to do any amount of processing in those callbacks. I am also
pretty sure that it i
Hi,
Are there any plans to revamp the mono website?
Half the pages/links are broken. Most of the information also appears
to be out of date (except maybe for the download page???).
Xamarin's website seems mostly focused on the mobile side of things.
Maybe the mono non-mobile specific stuff could b
Dispose on async results is mostly to properly clear the
synchronization object (AsyncWaitHandle).
You can call dispose manually after calling EndSend(..) on the
AsyncWaitHandle. I do not believe this is required. It should be
called internally automatically.
This will not however fix the memory l
I wouldn't be surprised. There are other discrepancies with that

that hasn't been touched :)

Yes that particular memory leak was present in 2.10.6 for sure and
possibly in 2.10.8 as well. I was told this is claim fixed in master
but haven't tested yet.
Note that this affected all callbacks called from native code. GTK#
was hit pretty bad by this particular leak. If you search the mailing

Arrays in C#/.net don't allocate new elements for you when you access
an index outside the range of the list.
To add new elements, you must first allocate them and then Add them.
Only once it has been added to the list can you access them.
ie:
var list = new List();
// list is empty here, access w
In looking at the code in SortedList<>, I noticed the following things:
- Clear() causes a new allocation, this is inconsistent with other
generic containers such as List<> and Stack<> that simply perform an
Array.Clear() on their internal array.
- PutImpl(), if Find(key) throws an exception, it
Hi,
Using latest stable mono, I am getting a hang at process exit.

I know for a fact that all my threads have exited except the main
thread. It hangs when returning from main() or in Environment.Exit(0);

The behavior is the same with "Global\\" prefix, in that it fails to work.
I'll be sure to test this and report on the results as soon as I can.
Thanks

Hi,
I am using mono 2.10.6 under ubuntu 11.04.
Using the following line:
bool lWasMutexCreated;
Mutex lSystemMutex = new Mutex(true, "SystemMutex", out lWasMutexCreated);
The mutex is always acquired and created even if ran from multiple
concurrent processes. I also tried using Mutex(false, "Syst

Hi,
I'm attempting to track down a memory leak in my application.
I managed to run heapshot a number of times as described in the wiki
page but unfortunately, now my application fails to start every time
with the profiler enabled.
Running a debug build on ubuntu 11.04 + mono 2.10.2 produces:

Hi,
Over the weekend, I noticed the following behavior in my application.
I run the latest mono on top of ubuntu 11.04. (Dual installation)
I have an application A that launches a child application B (both C#,
both mono).
Over STD IN/OUT I transfer to application B the PID of application A.
The id
