Does anybody know of a good Win32 API reference for C#. I am able to find API references, but everything is in C++. There are different handles and data types that I don't know how to convert to C#.

Given that Win32 is a C API, its use of the first two is unsurprising. Given that MS supply and support a C++ compiler, the existance of the last two is not surprising either.

It's 2020, and Microsoft is still juggling two very different APIs (application programming interfaces) in Windows 10. In one corner, you've got the old-school Win32 API and its decades-long legacy.
