I was working with some custom build definitions on a training course last week and one of the delegates had a failing build.  After a quick visual inspection I couldn’t spot what was wrong and so I wanted a way of easily comparing the build with my working build definition.

I knew we could pull the information using the TFS API and the IBuildDefinition Interface but I came across a flag on the TFS Power Tools (tfpt.exe) builddefinition option that I hadn’t realised was there.

tfpt.exe builddefinition /diff “<Project>\<Build Definition 1>” “<Project>\<Build definition 2>” /collection:<collection url>

This gives us a really quick and simple way of comparing the build definitions and it uses the Visual Studio file comparison to show the differences.

For more information on the command, launch a Developer Command prompt and type:

tfpt builddefinition /diff /collection:<collection url> /?


So, for example on my demo setup

  • Server = TFS2013
  • Collection = RippleRockCollection
  • Team Project = BuildDefinitionTest
  • Baseline Build = BuildDefinition1
  • Build for Comparison = BuildDefinition2


I used:

tfpt builddefinition /diff “BuildDefinitionTest\BuildDefinition1” “BuildDefinitionTest\BuildDefinition2” /collection:http://TFS2013:8080/tfs/RippleRockCollection

You’ll probably find an error saying:

Could not load file or assembly 'Microsoft.TeamFoundation.Build.Workflow, Version=, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.


You can find Microsoft.TeamFoundation.Build.Workflow.dll in:

C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\PrivateAssemblies

and simply copy the file to:

C:\Program Files (x86)\Microsoft Team Foundation Server 2013 Power Tools

Tfpt.exe should now launch Visual Studio and make the definitions very easy to visually compare side-by-side.
