How to cancel an ongoing operation on lab environment programmatically?

MTM provides users to do bunch of operations on lab environments and a lot of these operations are long running. MTM also provides a gesture to cancel the operation but in case you want to cancel it programmatically, you can use the following script. Here is how you can use the following script.

• Login to a machine with tfs object model installed. (The tfs object model gets installed with VS, MTM, Tfs, test controller etc)
• Open notepad, copy paste the following script and change the highlighted variables as per your setup/deployment.
• Open a power-shell command prompt and run the modified power-shell script.
• It should cancel the operation

Enjoy !!
