Description

No issue is raised for static nested class fields that are not shared among instances of different close constructed types. (S2743)

Repro steps

        public class StaticFieldInGenericClass<T>
            where T : class
        {
            public static T tProp { get; set; }

            internal string NestedClassUsage => NestedClass.StringField;

            private static class NestedClass
            {
                public static readonly string StringField = "String"; // FN
            }
        }

Expected behavior

Issues are reported for the fields of the static nested class as they are not shared among instances of different close constructed types.

Actual behavior

No issues are reported.

Known workarounds

None
