Where is String.Intern method in .NET Core?

Question

I've created new .NET Core console application and can not find string interning methods.

Here's an old doc: https://msdn.microsoft.com/en-us/library/system.string.intern(v=vs.110).aspx

Taken from the github issues page of IronLanguages (that had the same problem):

String.Intern will be added in .NET Standard 2.0, which will also be implemented by .NET Core:

https://github.com/dotnet/standard/blob/master/netstandard/ref/mscorlib.cs#L3048

The github of corefx seems to support this: one of the missing function is System.String.Intern(System.String) and the issue is tagged as netstandard2.0.
