Delete project from TFS 2012

If you have ever used TFS, you can create a new project from Visual Studio directly. However, to delete a project, you need to use Team Foundation Server Console in a remote server which is not available in sometimes such as https://tfs.visualstudio.com/. You cannot access the server directly. So, the solution is we need to access remotely using command line tool from Visual Studio.
- Open Developer Command Prompt for VS2012
- The syntax command is TFSDeleteProject [/q] [/force] [/excludewss] /collection:URL TeamProjectName
- Example: TFSDeleteProject /collection:"https://xxx.visualstudio.com/DefaultCollection/" "Project X"

AutoResetEvent to synchronize threads

Sometimes when we are dealing with multithreading application, we need to lock some threads and waiting for another thread finished execution, in order to do that it needs some lock mechanism to lock other threads . So, in this post we have a solution that we can use AutoResetEvent class to block threads from execution. AutoResetEvent is a class to control lock mechanism and guarantee that after it is set, it will allow only one thread to continue, then reset automatically (become lock again). There is also another class named ManualResetEvent, which it concept is similar to AutoResetEvent class, however, the difference is we need to reset the lock mechanism manually. So, it means that it will allows threads at the same time to continue until we tell it to stop (reset it). By the way, in this post I would like to talk about AutoResetEvent class only. The usage scenario for this class is easy to follow as described in the following website:
