Answer 1

From the documentation for codeSubDirectories:

The build order is inferred from the top-down order of the codeSubDirectories collection. The App_Code directory is built last.

Which implies that when your C# code is being compiled, the VB code hasn't been compiled at that point. You might try and separate base classes, etc, and put them in an earlier subdirectory or into a compiled class library, but I'd probably recommend just writing your code in VB - it's not that tricky to write in one when you're used to the other - the framework is still the framework.
