I've taken a slightly different approach... instead of trying to bring all the directshow API's into a managed langauge, I just create higher level wrappers in Managed C++, do all the actual directshow stuff inside in unmanaged code, and just call the interfaces on my wrapper.

In most cases, you really don't need access to every single directshow interface in the application.

I just expose the functionality i need rather than trying to emulate the entire interface.

You can look at my code here...

http://svn.xiph.org/trunk/oggdsf/src/lib/player/libDSPlayDotNET/DSPlay.cpp

and a very simple .NET player which uses it.

Some of the stuff is specific to a particular media type i'm working on (annodex)

If you're playing around with DirectShow as part of your ramp up for Movie Maker development have you tried out the use of Direct3D pixel shaders for video effects?

If you say wanted to convert video frames to grayscale or add a swirl effect you can either write a DirectShow filter which runs on the CPU or using the VMR-9 (Video Mixing Renderer) you can use the GPU with pixel shaders to get the same effect at the end of the pipeline.

Here's the file that I used to create the .TLB using MIDL. You should create your own UUID with UUIDGEN instead of using mine.

import "devenum.idl";
import "axcore.idl";
import "axextend.idl";

[
uuid(22995cc9-e37e-4b96-9326-b418935ac4be),
helpstring("DirectShow interfaces")
]
library DirectShow
{
interface IFilterGraph;
interface ICreateDevEnum;
interface IGraphBuilder;
interface ICaptureGraphBuilder2;
interface IFileSinkFilter;
interface IFileSinkFilter2;
interface IAMAudioInputMixer;
};
