If you’re doing managed development and you’re searching for the .NET equivalent of your favorite Win32 functions, then this is the place to look. I think I reviewed this paper last year:
Microsoft Win32 to Microsoft .NET Framework API Map
This article identifies the Microsoft .NET Framework version 1.0 or 1.1 APIs that provide similar functionality to Microsoft Win32 functions. One or more relevant .NET Framework APIs are shown for each Win32 function listed. The intended audience for this article is experienced Win32 developers who are creating applications or libraries based on the Microsoft .NET Framework, but anyone looking for a managed counterpart for a Win32 function could find this document useful.
Thanks to Steve for the head’s up.
Update: I thought this was updated, but I made a mistake on the year. It’s still a great resource. 🙂
