Code inspection: Return of a variable captured by 'using' statement

This inspection reports returning a value that is declared in a using scope. The returned object will already be disposed when the caller receives it.

Example

                using System.IO;
                Stream OpenStream(string path)
                {
                    using var stream = File.OpenRead(path);
                    return stream;
                }
            

                using System.IO;
                Stream OpenStream(string path)
                {
                    var stream = File.OpenRead(path);
                    return stream;
                }
