BuildActivity ignores ToolsVersion

Question

For those of us not living inside build templates every day here’s the steps that got it working for me:

First find the template associated with your build (if you already know where to find it skip a couple steps).

Just right click the build definition and select Edit build definition
Select the Process tab and you’ll see the name of the template (quite likely to be DefaultTemplate if you haven’t customized it). On the far right click Show details to see the path for the template.

Find the template file and double click to edit it. It should come up in a graphical view like this. Scroll till you find Run MSBuild for Project

Click on the little icon on the right – don’t try and type it in because it’ll probably explode and crash Visual Studio.
Enter IN QUOTES the following "C:\Program Files (x86)\MSBuild\14.0\bin"

NOW FOR THE MOST IMPORTANT PART

For me the Run MSBuild for Project was in TWO places.

So I just repeated the above steps in both places, and then after I checked in the .xaml file my build FINALLY worked fine.

You may need to recycle the agent / controller from within the TFS tool.
