Extension fails to load on VS2015.2

[dpvreony]

Greetings

After updating to VS2015.2 build manager greets you with

Could not load type 'Microsoft.VisualStudio.Services.WebApi.Utilities.UserAgentUtility' from assembly 'Microsoft.VisualStudio.Services.WebApi, Version=14.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'.

Extension needs to be uninstalled due to how Visual Studio appears to load TFS related plugins via MEF, even when they are disabled.

Thanks

Hi, Can you check if Microsoft.VisualStudio.Services.WebApi.dll is installed into the GAC? The easiest way to do this is to check if there is a folder that starts with v14.0.0.0 under the c:\Windows\Microsoft.NET\assembly\GAC_MSIL\Microsoft.VisualStudio.Services.WebApi.

I suspect you have an assembly from VS 2015 RTM or VS 2015 Update 1 in the GAC. Uninstalling it, will fix the issue.

Hi

There's no sign of the dll in the gac.

The Global Assembly Cache contains the following assemblies:

When looking on the local system I can find
