yeah, it is possible for god sake,
but how?

any simple hello world example?

i was thinking baking the web browser control in .net (or GUI in .net)
but the logic stuff in asm..

possible?

I think .NET stuff would be well out of the realm of a small assembly proggy. From what I have seen you would need to set up a managed-code environment (i.e. a VM environment) and a .NET byte code decoder.

Even mscorlib.dll is actually MSIL code (I was very surprised about this as I assumed they used native code for the framework).

However, I also think it is possible, but you're very likely to need to run in unmanaged mode so you could callback your assembly code (not sure if it is feasible the other way around).

Maybe what you want is to make an assembly .dll using fasm and calling the assembly code from within .NET?

yeah, dll in fasm... calling from .net application.

and function in .net application, and call from fasm dll.

Maybe possible. But doesn't that break the managed code paradigm? What is the calling standard anyway?

This would be where it all goes haywire. Wouldn't you have to set up protected objects and other things in asm before doing the call?

Possible and yes, you need to run unmanaged. http://msdn.microsoft.com/en-us/magazine/cc164123.aspx

Passing callback, which would allow you to call managed code from the native dll is not so clear how possible and stable is, I found this (I've not read it thoroughly): http://www.beefycode.com/post/Delegates-and-Native-API-Callbacks-Answer.aspx

Well SleepSleep,
I made a simple C# example here that calls a .dll function made with fasm from within .NET code. Going in reverse, Calling a .NET dll function from assembly, I haven't had any experience with though.
