Assert.IsType(typeof(CreatedNegotiatedContentResult<Justif>), result);

and boom...

Ok this appears to be an xunit bug. The problem is I'm comparing a generic type, of the form SystemType<MyType>. The typeof() operator in the xunit project returns a strong name indicating my dll, whereas result.GetType() returns a strong name with the system dll.

The workaround is to compare just the Type.Name...

System.Type expectation = typeof(System.Web.Http.Results.CreatedNegotiatedContentResult<Justif>);
System.Type tristeRealite = result.GetType();
Assert.Equal(expectation.Name, tristeRealite.Name);
