Shouheng Yi commented on REEF-1971:
-----------------------------------

When using Visual studio to build the C# solution, I need to update my Windows SDK to the
latest version. This is done by using Visual Studio Installer.

> Hi REEF Devs,
> I was trying to build the latest master branch of REEF by following [BUILD.md|https://github.com/apache/reef/blob/master/lang/cs/BUILD.md].
I was using Visual Studio 17, and had JAVA_HOME, M2_HOME, protoc set in the PATH.
> However, when I was trying to build the project, it gave me this error message:
> bq. CS1617	Invalid option '7.2' for /langversion; must be ISO-1, ISO-2, Default, Latest
or a valid version in range 1 to 7.1.bq. 
> Any idea of how to resolve this? Thanks!
