I have found an issue with the TFS cloud service build, or perhaps it is just something that you currently don't support yet. I am working on a video game project in XNA v4 refresh. I just created a CI build and set my platforms to build to debug and release x86 (same as my configuration manager shows in Visual studio 2010, which is also default for XNA projects). I get the following error:
$/ChaosGalaxy/Dev/ChaosGalaxy3D/ChaosGalaxy3D.sln - 1 error(s), 0 warning(s), View Log File
C:\Program Files (x86)\MSBuild\Microsoft\XNA Game Studio\Microsoft.Xna.GameStudio.targets (34): Your installation of XNA Game Studio does not support this project (XNA Platform = 'Windows', XNA Framework Version = 'v4.0').
1 projects/solutions compiled
I believe the servers are missing XNA 4.0 in order to do automated builds in the cloud. Please let me know if this is an issue/bug, something you don't support yet, or what because this is a pretty big deal since I wanted to move to the TFS Cloud model but I can't lose my builds :(
