Dealing With Native DLLs in .NET “AnyCPU” Builds

A .NET application can be compiled using the “AnyCPU” configuration, meaning the application runs as 32 bit on a 32 bit OS, and 64 on a 64 bit OS. As long as the application is purely managed, everything should be just fine. However, if the application must use some native DLL through interop (e.g. P/Invoke), then “AnyCPU” may be an issue. A native DLL cannot be both 32 and 64 bit – it’s one or the other. The traditional solution to the problem is to switch the .NET build to a “Win32” or “x64” configuration...
