Unable to use .NETStandard1.7

[zipswich]

I am created an empty class library targeting .NETStandard1.6, and everything worked fine.
I switched the target to .NETStandard1.7, then building the library generated the following error:
C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\MSBuild\Microsoft\NuGet\15.0\Microsoft.NuGet.targets(162,5): error : Your project is not referencing the ".NETPlatform,Version=v5.0" framework. Add a reference to ".NETPlatform,Version=v5.0" in the "frameworks" section of your project.json, and then re-run NuGet restore.

Any remedy for this?

As was mentioned in #160 netstandard1.7 isn't a shipping version and shouldn't be used. Once we get a tools update and we ship the next version you will be able to target netstandard2.0 which will be the next version above 1.6.
