Code inspection: Immediate delegate invocation

This inspection reports a delegate that is created only to be invoked immediately. The extra delegate creation is unnecessary and makes the code longer and less direct.

                using System;
                class C
                {
                    void Log()
                    {
                    }
                    void M()
                    {
                        new Action(Log)();
                    }
                }
            

                using System;
                class C
                {
                    void Log()
                    {
                    }
                    void M()
                    {
                        Log();
                    }
                }
            

This inspection can also report immediately invoked lambdas or anonymous methods when they can be simplified safely.
