I just tried using the build service on team foundation service today since I noticed that I could deploy directly from there to the Azure websites. I am building a web application along with a number of supporting projects that build perfectly fine locally and that I can deploy to Azure and run without a hitch.

However, on TFS, the build fails. Here the chunk that fails and I can't figure out why that is (except that perhaps something just isn't configured properly for the TFS build for some reason):

Project "C:\a\src\Documents\Projects\*\*\*.csproj" (3) is building "C:\a\src\Documents\Projects\*\*\*.csproj" (4) on node 1 (default targets).

Does anyone have any ideas as to why it might be doing this? Alternatively, if this isn't the proper place to put this question, could someone please link me to an appropriate place?

I regenerated the EF model from the database and the issue has cleared up, so I'm marking this as resolved.

Just want to share one more thing regarding this Issue. Regenerating the entire models might be one of the solution. But would like to explain whats happening behind the scenes.

Normally, When you add a new item or file from your VS 2012 Solution, by default it will be added to your source control. The same happens for the edmx and the automatically generated .cs files. But when you manually delete an entity from the edmx designer and adding them again will create this type of issue.

When you delete them it creates an entry in the source control  and when you add them again it fails to mark them as add.

So the solution is make sure you add those files explicitly to the source control by right clicking and selecting "Add to Source Control"

Hope you understand.
