Following is the exact error message:
C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Microsoft.Common.targets (983): The reference assemblies for framework ".NETFramework,Version=v4.5" were not found. To resolve this, install the SDK or Targeting Pack for this framework version or retarget your application to a version of the framework for which you have the SDK or Targeting Pack installed. Note that assemblies will be resolved from the Global Assembly Cache (GAC) and will be used in place of reference assemblies. Therefore your assembly may not be correctly targeted for the framework you intend.
This occurs when your Build server does not have Visual Studio 2012 (which ideally should not be anyway), and it has only .NET Framework 4.5, and no Framework 4.5 SDK or .NET Framework Framework Targetting-Pack is not installed.
In order to get rid of these warning messages, you have two options:
1) Install SDK or Targetting-Pack for .NET Framework 4.5. But they are considerably large in size.
2) The other option is to copy following folder from your development machine to your TFS build machine.
C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.5
Doing this should fix the issue, and the warning messages will be disappeared.
