描述

Version Used: VS 15.5.5

Steps to Reproduce:

  1. Create a nested class, like this:
class A
{
    string PropertyA { get; }

    class B
    {
        void MethodB()
        {
            Console.WriteLine(nameof(PropertyA)));
        }
    }
}
  1. When typing nameof(P, PropertyA isn't shown as a suggestion, but the code compiles.

Expected Behavior: The code compiles and PropertyA is shown as suggestion.

Actual Behavior: The code compiles, but PropertyA isn't shown as suggestion.

研究方向
Investigate the nameof completion provider in Roslyn's completion engine. Look for how nested scopes are handled in the completion context. The issue likely requires modifying the provider to include members from enclosing types. Check existing tests for nameof completion and add a test for nested class scenario.
