Type-safe Managed wrappers for kernel32!GetProcAddress

Pinvoke is cool in managed code, but sometimes you need to get straight at kernel32!GetProcAddress. For example, maybe you need dynamic control over which unmanaged dll you want to load. But that returns a void*, which is a major no-no in managed code.

Visual Studio's IDE will copy code as RTF (Rich Text Format). Web browsers like HTML. So posting code from Visual into blogs means a decent RTF to HTML conversion. And having a technical blog means posting code. So I needed to solve this conversion problem.
