Commented Issue: Issue with normal Should Be call [12478]

Hi

I receive an exception when i make a call like this:

```
etuResponse.Header.RspCode.Should().Be(0);

```

Thats all. I am doing nothing else.
RspCode has the value 234.
I am using MSTest, Visual Studio 2012, .Net 4.5
FluentAssertion Version: 2.0.0.0

```
System.NotSupportedException occurred
HResult=-2146233067
Message=The invoked member is not supported in a dynamic assembly.
Source=mscorlib
StackTrace:

InnerException:

Comments: Hmm, I just noticed that the 2.0 version of the AttributeBasedFormatter is actually already intercepting that exception. Don't understand why it still bubbles through...
