Hi,
I'm hoping someone can help here.
In C++, if you create a com object in a thread running as an STA, &
then want to use it on another thread running either as an STA or MTA,
then the interface needs to be explicitly marshalled using, for
example CoMarshalInterThreadInterfaceInStream.

Now, if I have a C# dotnet project, & create a COM object using
Activator.CreateInstance & interop, & want to use this interface on
another thread, do I have to perform some marshalling (as above), & if
so, can anyone help with exactly how I would do this in c#?

I've scoured the groups before posting this, & found nothing, so it's
entirely possible I'm missing something obvious.

Thanks in advance for any help.

regards,
Clive
