To expand on Yurec's answer, lambdas provide syntactic support for both delegates and expressions. The compiler will usually be able to infer which is needed based on context. (As Yurec notes, this is the case for you.) So a lambda assigned to some delegate can be assigned to an expression wrapping the same delegate type.
