Lambda expression vs anonymous methods [duplicate]

Answer 1

The only difference is the lambda can be easily cast to Expression>. The delegates are purely just methods/closures, but the lambda can also be broken down into an expression tree:

Expression> expr = x => x*2; // Expression tree
Func fun = x => x*2;              // Function
delegate int MyDelegate(int x);             // Delegate
MyDelegate del = x => x*2;                  // Same as Function and Delegate
