pinvoke

I typically use the site http://www.pinvoke.net/ to grab a DllImport declaration whenever I need to call a Win32 API, and I've noticed it's the de facto standard response on Stack Overflow to API interop questions.

Is this what "everyone" does? Is there a better way? Does Microsoft offer an alternative? e.g. a tool that reads .h files and outputs an assembly.

Why aren't there some standard assemblies that just expose all the Win32 APIs? What would be the barrier to creating them and using them, as an alternative to a site like pinvoke.net?
