multi-file c++/cli .net assembly in ASP.NET web site

Question

I have a .NET assembly that I want to use in an ASP.NET web site. The assembly has the following characteristics:

• written in C++/CLI
• contains managed and unmanaged code
• compiled to x86/x64 platforms (using the correct platform-specific assembly, so it's not believed to be an issue here)
• compiled as a multi-file assembly linking several native dlls

When I try to compile I am getting an error stating:

Could not load file or assembly '...' or one of its dependencies. An attempt was made to load a program with an incorrect format.

I can use the library reference without problems in an ASP.NET web application (such as MVC), but when I want to use it in an ASP.NET web site, I get this compilation issue.It seems to be something specifically related to the ASP.NET compiler.

How do I get my website to compile with this dependency?

Answer 1

I don't see any compilation settings within Visual Studio to indicate one way or another...
