  • Hi,

    Are you able to run your project in VS 2015 locally?

    Before queuing TFS build, make sure the project can work locally in VS 2015. You could try to build your project in VS 2015 locally by removing and re-adding the assemblies to see whether the issue persists, also, please check the website below to see whether it helps you:
