In mono-4.0.0/9236ac4 and master/bd471cb, C#6-style "using static" directives do not appear to be consulted if the type is a nested type.
(Note that - for master - this is after the fix for issue 28976, which in any case only affected types in different assemblies.)
public class Constants
public class One
public override string ToString()
using static Constants;
static class Program
static void Main(string args)
$ mcs -debug Program.cs Constants.cs
Program.cs(7,37): error CS0246: The type or namespace name `One' could not be found. Are you missing an assembly reference?
Program.cs(8,34): error CS0246: The type or namespace name `One' could not be found. Are you missing an assembly reference?
Replacing "One" in both cases with "Constants.One" works, and produces the expected output:
Fixed in master
