Hi
when i try to build solutions created with VS 2013 I got an error:
Stage Awaiting Agent
No agents are currently available to execute the stage.
**haghost** : The expression, '$Agent.VisualStudio.2013.Path$' exists, evaluated false. '$Agent.VisualStudio.2013.Path$' does not exist
I tried to manually set the path in the agent variable to VisualStudio (currently there is only VS 2013 Web which doesnt have a devenv.exe liek previous versions)
I set the path to the exe that is called for starting it : C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\VWDExpress.exe
But still same error. what do i have to do ? Which version of visual studio is needed?

Hi Haggy,
We don't currenlty support building with Express versions of Visual Studio, so you need to install a full version. We'll look into whether it is possible for us to support Express versions in the future.

Do you have the portable library installed on the machine where the agent is installed?
