Code inspection: Redundant empty object or collection initializer

This inspection reports an empty object or collection initializer that does not initialize anything. In that case, the { } adds noise without changing the created value.

Example

                using System.Collections;

                class C
                {
                    object Create()
                    {
                        return new ArrayList() { };
                    }
                }
            

                using System.Collections;

                class C
                {
                    object Create()
                    {
                        return new ArrayList();
                    }
                }
            

Quick-fix

The quick-fix removes the empty initializer. When useful, another quick-fix can fill the initializer with writable members instead of removing it.
