Mock.Of<foo> Setting return for Method Calls With Parameters

Trying to figure out how to set up a Method that has parameters using Linq to Mock

Mock.Of<foo>(f=> f.Method(It.IsAny<DateTime>(), It.IsAny<DateTime>()) ==
        Func<DateTime,DateTime,List<DateTime> = (date1,date2){ /*stuff*/ });

something like that, have tried a few variations and been digging around the web. I'm confidant I have done this before but for the life of me can't find what im missing.

This will set up your Mock to return expectedResult if your method is called with parameters date1 and date2.

var bar = Mock.Of<foo>(f => f.Method(date1, date2) == expectedResult);

I'm still trying to figure out if there is a way to set it so that the Mocked method returns it's own input, but haven't yet with the new .Of method.

With Moq, assuming your interface is like this:

interface foo 
{ 
    List<DateTime> Method(DateTime date1, DateTime date2); 
}

The syntax I think you're looking for to setup the mock is

var bar = new Mock<foo>();
bar.Setup(f => f.Method(It.IsAny<DateTime>(), It.IsAny<DateTime>()))
   .Returns<DateTime,DateTime>((date1, date2) => new List<DateTime> { date1, date2 });

Edit

After searching around, I found this which I think other syntax which I think is what you are looking for:

var bar = Mock.Of<foo>();
Mock.Get(bar).Setup(f => f.Method(It.IsAny<DateTime>(), It.IsAny<DateTime>()))
   .Returns<DateTime,DateTime>((date1, date2) => new List<DateTime> { date1, date2 });
