Action delegates break mutation process #2925

Closed richardwerkman closed 2 months ago

richardwerkman commented 2 months ago

Describe the bug During improving the integration tests with various constructs I noticed the following code breaks stryker:

        Action greet = delegate { Console.WriteLine("Hello!"); };
        greet();

        Action<int, double> introduce = delegate { Console.WriteLine("This is world!"); };
        introduce(42, 2.7);
