title: What is needed to run Roslyn on Teamcity?
body: <p>With Visual Studio 2015 having been released yesterday my dev team is very interested in upgrading and using the new C# 6.0 features and as we all have MSDN it is something that would definitely be possible.</p>
  
  <p>However I am worried that our Teamcity builds will fail without performing some work to upgrade the build agents.</p>
  
  <p>So has anyone gone through this process yet, or know what would be needed?</p>
  
  <p><strong>Edit:</strong> I did some research into Teamcity and noticed that on the <a href="https://www.jetbrains.com/teamcity/whatsnew/" rel="noreferrer">What's New</a> page for version 9.0 and 9.1 that it adds support for VS 2015, so does that cover what would be needed? And also since we are running TeamCity 8.0 would there be any way to add Roslyn support without upgrading?</p>
