.NET background threads

[Guest]

I have created a simple C# application which instantiates an object of a
class I defined and calls a single method on the class. When I run the
application in the debugger, I see there are 3 threads, one of which is my
application. I am unable to determine what the other 2 threads are because
no source code is available. I'm assuming they are .NET threads, but don't
know what they are or why they are running. What are these threads and is
there a way for me to get info about threads for which no source is available?

Try using windbg and the sos extension. But I warn you - this is not for the
faint-of-heart

Those background threads you see are most probably asynchronous calls
