Meaning of () => Operator in C#, if it exists

Question

I read this interesting line here, in an answer by Jon Skeet.

The interesting line is this, where he advocated using a delegate:

Log.Info(\"I did som         


        

Answer 1

It's way to pass anonymous delegate without parameters as lambda expression.

Similar to this from .NET 2.0

Log.Info("I did something: {0}", delegate()
            {
                return action.GenerateDescription();
            });
