DLR/dynamic support

Hi, Is there a way to make FluentAssertions work with dynamic/DLR? Consider the following code:

dynamic expando = new ExpandoObject();
expando.someVar = "string";
expando.someVar.Should().Be("string");

which throws Microsoft.CSharp.RuntimeBinder.RuntimeBinderException: “‘string’ does not contain a definition for ‘Should’”

Thanks!

I am using cast to object as a workaround, but where I am specifically wanting to test the type of a dynamic e.g.

// field.value is dynamic
field.value = "xyz";
((object)field.value).Should().BeOfType(typeof(string));

FWIW the same cast would work for the OP

 ((object)expando.someVar).Should().Be("string");

Not until C# supports calling extension methods from dynamic objects…
