I have an c# app which creates and starts a directshow graph on the firing of a Threading.Timer event. some time later a different Timer instance attempts to stop and dispose the graph via Marshal.ReleaseComObject(theGraph).

This causes a threading issue and visual studio tells me that I risk data corruption by attempting to dispose of the com object (the graph in this case) from a different thread other than the one it was created on.

How do I get back onto the original thread to stop and dispose the graph?

I know very little about threading and I’ve been ignoring the issue, but I have some time now to learn more about threading and how I should make correct use of it.

any pointer most welcome.
