问题
First time i am trying to access the build definition from release template and the dropdowns are empty.

Did I miss any permission setting?

I have installed RM server and client in the build server, now I am able to access the build definition. Previously there were no domain trust between build server and RM installed server, but I was able to connect TFS. Issue was related to domain trust I believe...!
