Our team is going to release a 1.1 update of the VSCmdShell tool window for Visual Studio and we are spending the day looking for bugs. Because the project is public you can participate as well. Head on over to the codeplex site
sign in, and file some bugs. You can see all the existing bugs we're filing as well. We'll be starting the bug fixing next week and targeting a 1.1 release by mid-September that will hopefully remove any adoption blockers.
VSCmdShell provides users with a shell window inside the Visual Studio IDE that can be used for Visual Studio commands as well. Current version allows user to use either Windows Command Shell (cmd.exe) or Windows PowerShell.
