Adam Nathan has created a home for a ton of PInvoke signatures, organized by Module/DLL and pre-populated (by the man himself) with a ton of the most common signatures… I’ll let the site describe itself with this text from the “What is this site?” page;

[PINVOKE.NET](https://pinvoke.net/) attempts to address the difficulty of calling Win32 or other unmanaged APIs in managed code (languages such as C# and VB .NET). Manually defining and using PInvoke signatures (also known as Declare statements in VB .NET) is an error-prone process that can introduce extremely subtle bugs. The rules are complex, and if you make a mistake, you’ll probably corrupt memory.

For those of you who are primarily VB.NET developers (like myself), I fear you will find the VB content a bit light on this site... but this is bound to change over time since, as was mentioned earlier, this **is** a Wiki and I'm sure people will be adding VB.NET signatures...
