How to install svcutil.exe under Windows 10

C:\Program Files (x86)\Microsoft SDKs\Windows\v10.0A\bin\NETFX 4.6.1 Tools

As @AlexK. pointed out in his comment, the svcutil.exe is available via the "Developer command prompt for vs2017" start menu item.

I found out the path via where svcutil and added it to my PATH environment variable. Now I can use it as required. Thanks again!
