Marshaling between Managed and Unmanaged Code: PInvoke Interop Assistant
I recently saw this useful tool mentioned on StackOverflow by JaredPar (it seems I need to catch up on the MSDN magazines that are starting to pile up!): the PInvoke Interop Assistant hosted on CodePlex and first described in this MSDN article, Marshaling between Managed and Unmanaged Code:
.NET Framework interop opens a channel between managed and unmanaged code, and marshaling plays a very important role in that connection in that it allows for data exchange between the two. There are many factors that affect the way the CLR marshals data between the unmanaged and managed worlds, including attributes such as [MarshalAs], [StructLayout], [InAttribute], and [OutAttribute] as well as language keywords such as out and ref in C#.
