CLR customize project

1. The Windows SDK version 8.1 was not found in VS 2015 update 3
2. Earlier releases
3. Online GUID Generator
4. Common macros for MSBuild commands and properties
5. ERROR: Cannot open source file “ ”

This problem happened to me after importing an old VS2003 solution into VS2017.
To fix it, I had to change "Windows SDK version" in project settings > "Generic" to the latest "10.x.x.x" version available from the drop-down list.

6. Visual Studio 2010 Professional: Cannot find include file “new.h”
