compiling a .net application with either a 32-bit or 64-bit dll

Question

I have an application that we wrote here at work that uses the SharpSVN wrapper for SVN. It has served us well of the past few years. However, we have started bringing in 64-bit

Answer 1

From the description, it sounds like your vb.net application is built with the Any CPU option, which means it would run as a 64-bit application on a 64-bit machine. In that case, it would not load the 32-bit DLL.

Rather than try to use both a 32-bit and 64-bit version, you should be able to just change it to run as 32-bit. Simpler deployment. Under the project properties build tab, choose x86.
