resolve launch application to file extension from registry using C#?

[JDeats]

When a user double clicks on file item in Windows Explorer, Windows
tries to open the document with whatever application is related to
it's file extension.

In my WinForms application I would like to be able to shell out and
launch referenced applications in this way (to simplify what I'm
trying to accomplish, let's say I'm trying to create a Windows
Explorer like application using WinForms and C# for .NET 2.0

What's the best way to go about resolving the appropriate launch
application to the document file extension? Is there a location in the
registry I can check?

Thanks.

I discovered this is not necessary, turns on Process.Start handles it
for you:

E.g.
System.Diagnostics.Process.Start("c:\myfile.doc")
