Add an entry point to your assembly:

Then compile the assembly with /target:exe (you can rename it to .dll

and before calling other methods. See main_function () in
one of Mono's embedding samples:

Robert,
Thanks for the help, it worked like a charm! Calling an apple an orange
is weird, but in this case it does make sense.

Re: [Mono-dev] Gmcs fails with errors, but no error messages
Hi, Thanks for the response, but that doesn't give any more information. Do you think running in gdb would help? Could you give it a try with revision newer than r141469.

[Mono-dev] Unsafe struct array reading
Hi all,
I'm looking for a way to read and write array of structs from a file
(byte array).
I've the code (below) to read *one*, but I don't know how to map an
entire array.
I know there's a thousand of ways to do it with Streams, but the point
is for performance reasons I need to load them all on a single step (as
you'd do with C and fread).
Thank you

Re: [Mono-dev] Gtk depends on Winforms ¿?
On Sat, 2009-09-05 at 09:15 +0200, Christian Hoff wrote: In Windows I use 'mkbundle' [1] We should probably put that code in a try-block. What do you think, Mike? My question would be, what do you do in the catch block? The winforms reflection thing is a huge hack, we know that, and the poster is tripping over it because of using mkbundle instead of depending on mono or .Net. We could also take the stance that if somebody wants to do this sort of minimal packaging, they are required to add an artificial ref to swf to ensure it gets bundled. But they won't have any clue that's required if we just silently fallback to unthemed windows when we can't find swf. According to Robert Jordan on this thread, it's a PeekMessage/GetMessage loop that's required to happen before the first handle is created. We should try a pinvoke solution like that and see if it works so we can remove the hack altogether instead of figuring out ways to make the hack more palatable.

[Mono-dev] [patch] coreclr fix for internal calls
Hello,
Here's a patch to throw SecurityException (unlike p/invokes
MethodAccessException) for internal calls defined outside platform code. The
patch also tries to reduce some code duplication for other coreclr
exceptions thrown inside mini/method-to-ir.c
Sebastien
p.s. the test cases (moonlight unit tests) also show a difference between
[s]mcs and csc - not sure what the specs are (if any) for this case but I do
prefer smcs behavior :)

Re: [Mono-dev] An asynchronous System.Runtime.Remoting.Channels.Tcp
Hello, I like this patch very much, and I like that the way to enable it is through the new run_async configuration option. My only feedback is that I believe this is a nice enough feature that it deserves at least: * A blog entry announcing it, linking to: * A page on the Wiki with an explanation of what it does, and how to use it. Miguel. Hi all Attached is a patch to add an optional asynchronous path for the TCP remoting channel server. The main benefit we see with this change is in reliability; when a single server is servicing many clients at once (we test with over 100) with large data transfers the standard synchronous channel will often drop connections. We tracked this down to the Accept() call in TcpServerChannel.cs not being able to get to incoming connections quickly enough. I was hoping that throughput of large transfers might be improved by using the threadpool's asynchronous sockets support, but it turns out that performance is pretty much the same as the current implementation.
