New Post: Feature Branch plan and Automated Builds

After studying the branching guide, I've come to the conclusion that the Feature Branch plan would work the best for our team.

I'd like to make this as easy as possible for the devs on my team, so I'm looking for a way to set up a build definition that will build and deploy our web app to a test location for the currently open solution. I seem to be stuck because the build definition requires a solution file in "Projects to Build", and this would be changing for every branch.

Is there any way to configure the build process to build the currently open solution?
