According to this it's just a install and go for Visual Studio 2013:

In fact, installing the C# 6.0 compiler from this release involves little more than installing a Visual Studio 2013 extension, which in turn updates the MSBuild target files.

So just get the files from https://github.com/dotnet/roslyn and you are ready to go.

You do have to know it is an outdated version of the specs implemented there, since they no longer update the package for Visual Studio 2013:

You can also try April's End User Preview, which installs on top of Visual Studio 2013. (note: this VS 2013 preview is quite out of date, and is no longer updated)

So if you do want to use the latest version, you have to download the Visual Studio 2015.

It worth mentioning that the build time will be increased for VS 2015 users after   Install-Package Microsoft Net Compilers   Those who are using VS 2015 and have to keep this package in their projects can fix increased build time   Edit file packages Microsoft Net Compilers 1 2 2 build Microsoft Net Compilers props and clean it up  The file should look like    lt Project DefaultTargets  Build            xmlns  http   schemas microsoft com developer msbuild 2003  gt   lt  Project gt    Doing so forces a project to be built as it was before adding Microsoft Net Compilers package

It is possible to use full C  6 0 features in Visual Studio 2013 if you have Resharper  You have to enable Resharper Build and voil    In Resharper Options -  Build  - enable Resharper Build and in  Use MSBuild exe version  choose  Latest Installed   This way Resharper is going to build your C  6 0 Projects and will also not underline C  6 0 code as invalid   I am also using this although I have Visual Studio 2015 because    Unit Tests in Resharper don t work for me with Visual Studio 2015 for some reason VS 2015 uses a lot more memory than VS 2013    I am putting this here  as I was looking for a solution for this problem for some time now and maybe it will help someone else

Under VS2013 you can install the new compilers into the project as a nuget package  That way you don t need VS2015 or an updated build server   https   www nuget org packages Microsoft Net Compilers   Install-Package Microsoft Net Compilers   The package allows you to use build C  6 0 code syntax  Because VS2013 doesn t natively recognize the new C  6 0 syntax  it will show errors in the code editor window although it will build fine   Using Resharper  you ll get squiggly lines on C  6 features  but the bulb gives you the option to  Enable C  6 0 support for this project   setting saved to  DotSettings    As mentioned by  stimpy77  for support in MVC Razor views you ll need an extra package  for those that don t read the comments   Install-Package Microsoft CodeDom Providers DotNetCompilerPlatform   If you want full C  6 0 support  you ll need to install VS2015

A lot of the answers here were written prior to Roslyn  the open-source  NET C  and VB compilers  moving to  NET 4 6  So they won t help you if your project targets  say  4 5 2 as mine did  inherited and can t be changed    But you can grab a previous version of Roslyn from https   www nuget org packages Microsoft Net Compilers and install that instead of the latest version  I used 1 3 2   I tried 2 0 1 - which appears to be the last version that runs on  NET 4 5 - but I couldn t get it to compile    Run this from the Package Manager console in VS 2013   PM gt  Install-Package Microsoft Net Compilers -Version 1 3 2   Then restart Visual Studio  I had a couple of problems initially  you need to set the C  version back to default  C 6 0 doesn t appear in the version list but seems to have been made the default   then clean  save  restart VS and recompile   Interestingly  I didn t have any IntelliSense errors due to the C 6 0 features used in the code  which were the reason for wanting C 6 0 in the first place      version 2 0 1 threw error The  Microsoft CodeAnalysis BuildTasks Csc task could not be loaded from the assembly Microsoft Build Tasks CodeAnalysis dll  Could not load file or assembly  Microsoft Build Utilities Core  Version 14 0 0 0  Culture neutral  PublicKeyToken b03f5f7f11d50a3a  or one of its dependencies  The system cannot find the file specified  Confirm that the  declaration is correct  that the assembly and all its dependencies are available  and that the task contains a public class that implements Microsoft Build Framework ITask   UPDATE One thing I ve noticed since posting this answer is that if you change any code during debug   Edit and Continue    you ll like find that your C 6 0 code will suddenly show as errors in what seems to revert to a pre-C 6 0 environment  This requires a restart of your debug session  VERY annoying especially for web applications
