you've got method parameter called e, can't introduce lambda expression parameter called e. you'll need rename 1 of them.

as shorter example, show has nothing ef etc:

// invalid: same variable name twice void foo(string x) {     action<int> action = x => {}; }  // valid: different variable names static void foo(string x) {     action<int> action = y => {}; }
