The purpose of this library is to allow access to Microsoft's DirectShow functionality from within .NET applications. This library supports both Visual Basic .NET and C#, and theoretically, should work with any .NET language.

Microsoft's managed solution to allowing access to DirectShow from .NET isn’t nearly as complete as the DirectShow interfaces for C++. For developers who want the complete range of functionality of DirectShow in .NET, this library provides the enums, structs, and interface definitions to access them.

Reviewing the source code will show that there is very little executable code in this library. There are a few helper functions (mostly in DsUtils.cs), but everything else in the library is just definitions.
