I'm moving CI setup from TeamCity to Visual Studio Team Services (was VS Online) switching to the built in Team Services Git. It all seems good but in TC I was able to set it up to automatically build all branches on check-in. This gave lots of benefits and significantly streamlined my process.
Team Services seems to insist that I have a branch filter, does anyone know how I can make turn this into a "build all branches" situation (or why I shouldn't build all check-ins on all branches!)
