Visual Studio 2017: Switch C# version

For those who need some more help the steps are described here:

  1. Right click on the project name and select Properties from context menu
  2. Select Build tab from left
  3. Scroll down and click Advanced button to open advanced build settings
  4. From Language version dropdown select C# version you are interested in

C# latest minor version (latest) is the option to select if you want latest version of C#.

NB! If you are writing some program that is later deployed to some other box be careful when playing with these settings as target environment may use older version of C#. Make it sure first what version of C# is available on target environment and then make your selection.

Same steps work also for Visual Studio 2015 but C# 6.0 is currently the latest version of C# available there.
