.NET Core GitVersion -showvariable exception

[snovak7]

Hello, I have installed nuget package for netstandard: This version has an error when I want to make -showvariable, any showvariable, it returns:

System.NotImplementedException: The method or operation is not implemented.
   at GitVersion.VersionVariables.ContainsKey(String variable) in C:\projects\gitversion\src\GitVersionCore\OutputVariables\VersionVariables.cs:line 196
   at GitVersion.VersionVariables.TryGetValue(String variable, String& variableValue) in C:\projects\gitversion\src\GitVersionCore\OutputVariables\VersionVariables.cs:line 181
   at GitVersion.SpecifiedArgumentRunner.Run(Arguments arguments, IFileSystem fileSystem)
   at GitVersion.Program.VerifyArgumentsAndRun()

Without options, I get a valid JSON output.

Yup the .NET Core implementation of this command was omitted in #1269
It just needs implementing really. I'll mark this as up for grabs.

Well I just used whats in the NETDESKTOP and it worked. You should add NETSTANDARD option there aswell. And here's the patch.
patch_1469.txt

This was made on master branch so Version 4
