Embedding native code in a .NET DLL

[Jon Harrop]

I would like to embed a high-performance native-code BLAS implementation in
a .NET DLL. What is the recommended way of doing this?

Hi,

I do not think you can do that. you will have to distribute both dlls.

Ok, thanks. Is it possible to have an optional dependency on another DLL? So
users could provide their own BLAS implementation and our DLL would use it
if available but would resort to managed code otherwise?

C++

Specifically, C++/CLI. The native code doesn't have to be C++ though, you
can link any static library with a C++/CLI wrapper into a single mixed-mode
assembly.

Note that this is the wrong group for such things, which is why you'll get
people telling you it can't be done.

Can I then statically link that DLL into a C# DLL?

What is a more appropriate (language agnostic if possible) group?

Thanks,

You said "into a .NET DLL". The C++/CLI compiler creates assemblies that
can be used from any .NET language, just as if it were a C# DLL.

You can also compile your whole program into .netmodule files and use the
C++/CLI linker to create the executable. The C# compiler hasn't any concept
of static linking though, you must use the C++/CLI linker for this even if
some of the code was compiled in C#.
