Question

Hi,

I am getting below error in tfs 2015 build.

Error CS1705: Assembly 'Microsoft.TeamFoundation.TestManagement.Client' with identity 'Microsoft.TeamFoundation.TestManagement.Client, Version=14.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' uses 'Microsoft.TeamFoundation.Client, Version=14.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' which has a higher version than referenced assembly 'Microsoft.TeamFoundation.Client' with identity 'Microsoft.TeamFoundation.Client, Version=12.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'

Answer 1

Do you have a project that have a reference to Microsoft.TeamFoundation.Client? then you need to change the reference to either version 14.0.0.0, from 12.0.0.0 or remove the setting specific version. it is done in your c# project.

Hi!

Maybe you have to install VS 2013 on your build server. Or update your application to use libraries from VS 2015.
