Can’t assign to delegate an anonymous method with less specific parameter type

by

Jared is of course correct that this is by design.

The reason for that design is that in the contravariant method conversion case, you might have a method that you didn’t write, and be assigning it to a delegate variable that you didn’t write either. You don’t control the types. So we go a bit easy on you and let the parameters match contravariantly and the return types match covariantly.

In the lambda-to-delegate conversion, you do control the thing being assigned. There is nothing stopping you from making it an exact match in the parameter types and therefore we require you to. No fudging allowed here.
