I’ve had my current installation for a few months now, and I’ve used it for development purposes. Today I suddenly encountered an error when trying to add items to the Toolbox. Visual Studio 2008 simply disappeared… No errors, no warnings, it just went away.

After some searching and a lot of trying, I found that deinstalling the PowerCommands for Visual Studio 2008 did the trick. I’m guessing that the installation of a service pack (for either Visual Studio or .NET Framework) changed something somewhere, making Visual Studio disappear into thin air when having PowerCommands installed and clicking the ‘Choose items’ context menuitem. Anyway: the problem is gone now…!

According to some forumposts I read reinstalling the PowerCommands after this problem was solved does not cause the problem to reappear. I haven’t come to testing that yet ’cause I’m working on a deadline here… (Why do these things always happen when you have a deadline…?)

Hope this helps.
