If your class uses external resources but will not be used on a design
surface, 
implement System.IDisposable, or derive from a class that 
directly or indirectly implements IDisposable.

How about trying

System.Runtime.InteropServices.Marshal.ReleaseComObject(myobject);

Subject: [ADVANCED-DOTNET] COM Interop and freeing references

Hi,

I have a .net app that uses a legacy COM Server component built as a VB6
ActiveX Exe.

I have added a reference to it using Visual Studio 2003 References menus
and can use it perfectly well from my C# app.

When the component is used, Windows runs it in a separate process. If
you're using this in a VB app then you can simply free the reference by
doing a "Set myref = null" and the process automatically disappears.

The problem is how can I achieve the same effect in .Net/C#. The
component is designed to be activated and released many times during the
lifetime of an application, if the reference cannot be freed then you
will have many of these processes running. Even if the reference to the
component goes out of scope or is set to null it does not release the
process. I would think that it would be released if the reference is
garbage collected but it is not possible to directly invoke a collection
(I've tried GC.Collect() with no effect).

Any suggestions?
Thanks
Permjeet Pandha
