See remarks for discussion of closures. Suppose we have an interface:
public interface IMachine<TState, TInput>
{
TState State { get; }
public void Input(TInput input);
}
and then the following is executed:
IMachine<int, int> machine = ...;
Func<int, int> machineC...
Expression<Func<int, bool>> checkEvenExpression = i => i%2 == 0;
// lambda expression is automatically converted to an Expression<Func<int, bool>>
