  • Hi,

    I have created a VS 2014 CTP2 VM in Azure. But it does not have the Roslyn compiler enabled.

    Alas, I only have access to the VS Professional SKU in my MSDN subscription.

    Is there a way to enable Roslyn in the VS Professional or is it available just for the Ultimate edition?

    Thanks for your superb show.

  • Hi Eduardo,

    Do you mean Visual Studio "14" CTP2? (There's no release date yet, so we're calling it "14" -- which is the major version number of VS.) The Roslyn compiler is certainly enabled in Visual Studio "14". Actually, there really isn't a way to disable it. In Visual Studio "14", the Roslyn compilers are the only C# and VB compilers.

    That said, many of the new C# and VB language features are not available by default. We're still working hard on them and you have to make a small tweak to your project to enable them. Just add <LangVersion>experimental</LangVersion> to your project file and the new language features will "light up" and be available to you. There's more information about this here.

  • Hi Dustin,

    Thanks for your reply.

    Yes VS 14 CTP2. I added the <LangVersion>experimental</LangVersion> to my project file and the new language features do not appear to be available and are reported as errors when I try to use them.

    That is why I have added this posting originally.

  • Hi Eduardo,

    That doesn't sound good! Would you mind filing an issue on Microsoft Connect? On the feedback form, be sure to specify Visual Studio Professional "14" CTP 2 for the Visual Studio/.NET Framework Tooling Version.
