        Why is this an issue?

        More Info

        Naming the members of an inner class the same as the static members of its enclosing class is possible but generally considered a bad practice. That’s because maintainers may be confused about which members are being used in a given context. Instead the inner class member should be given distinct and descriptive name, and all references to it should be updated accordingly.

        class Outer
        {
          public static int A;
        
          public class Inner
          {
            public int A; // Noncompliant
        
            public int MyProp
            {
              get => A; // Returns inner A. Was that intended?
            }
          }
        }
        

        Here’s an example of compliant code after renaming the inner class member, this way the property will return the Outer A:

        class Outer
        {
          public static int A;
        
          public class Inner
          {
            public int B; // Compliant
        
            public int MyProp
            {
              get => A; // Returns outer A
            }
          }
        }
        

        Or if you want to reference the Inner A field:

        class Outer
        {
          public static int B;
        
          public class Inner
          {
            public int A; // Compliant
        
            public int MyProp
            {
              get => A; // Returns inner A
            }
          }
        }
