Maruis Marais from CodeProject.com was nice enough to share is extensive library of Visual Studio 2005 Unit Testing Code Snippets (C#). A VB.NET set would sure be nice! Upon trying to install these code snippets, I realized that the Code Snippets Manager does not show-up on my Tools menu in Visual Studio 2005 and I have no idea why. I can still access the manager by typing Ctrl+K then Ctrl+B, but it would be nice if I could just go to the Tools menu because I know I’ll forget that key combination! 
Update: I was able to add the Code Snippets Manager back to the Tools menu by opening VS.NET 2005 and navigating to Tools > Customize... > Commands (Tab) > Category: Tools and then dragging the Code Snippet Manager back into the Tools menu.
