MSBuild error - Solution is of version 12.00 which is not currently supported

Question

I have a Build server which has TFS 2010 Build Service installed. I have 2 Build Agents and 1 Controllers configured. One of our projects have been converted to Visual Studio 2012.

I found out that .NET framework 4.5 comes with new version of MSBuild which is version 4.5.

I installed .NET framework 4.5 on the Build Server because prior to installing it every time the project was built I kept getting the following error:

"Solution is of version '12.00' which is not currently supported".

After installing .NET 4.5, I still run into the same issue.

How could I go about resolving this?

Do I have to configure the Build Agent to use the new MSBuild 4.5 in order to build this particular project or do I set something in the projects solution file itself? If so how?

I would really appreciate if somebody could assist me with this please?

Answer 1

Try install vs2012 on the build server, while i don't believe it's strictly needed it's the easiest way to get all the requirements installed.

Answer 2

We have installed VS2012 on the build agent. Interestingly when I RDC to the build agent and then run msbuild from the command line everything works fine. So the issue looks like it happens before we even get to MSBuild.
