Creating a 32 bit wrapper for a 64 bit dll. Is this possible?

I have a couple of dlls that are x64, with the x86 versions not being released yet. I want to use these in a x86 environment. There is no way to change any of the platforms of those factors.

I have tried searching the Internet, but to no avail. What I want to do is somehow create a x86 library that can communicate with the x64 ones. Is this possible at all? If so, how?

Preferably, the wrapper will be in C# code, though it has to be able to access C++ dlls. (The x64 libraries are written in unmanaged C++.)

You cannot do this within a single process. That's because a 32 bit process can only load 32 bit modules, and a 64 bit process can only load 64 bit modules.

The only way for your 64 bit code to call 32 bit code, and vice versa, is to use an out-of-proc solution. For example an out-of-proc COM server.
