Description

Version Used: 17.11.0 Preview 3.0

Steps to Reproduce: Test1.cs

global using MyInteger = int; // Rename here…

Test2.cs

public class C {
  public MyInteger M() => 42; // …or here
}

Rename the MyInteger using alias in any of the two places.

Expected Behavior: The using alias should be updated in both places.

Actual Behavior: Only the using alias declaration is updated. This looks especially weird when you start the rename from the usage.

Contributor guide

Research direction
Inspect the rename refactoring code for global using directives. Ensure that when a global using alias is renamed, both the using directive and all usages of that alias are updated.
