Downloaded Visual Studio 2010 Express, because I need to use the parallel programming in my project, and it’s the first time I came across the ConcurrentDictionary example on the Internet, but VS complained that it couldn’t find the namespace, so I decided to look it up in the Object Browser, and I noticed it’s not there, and most of the menu are gone!

At first I thought it is stripped out in Express edition, after playing with the menu, I figured the default setting is the Basic setting, can easily change from Tools –> Settings –> Expert Settings , and hence all the familiar menu came out.

Never encountered this situation before as this is the first time using Express edition…
