Enum type isn't binding from QueryString

[derekgreer]

I've got an enum type which I've declared as a property on a model and am issuing an HTTP GET request. I found that the value being passed in wasn't binding to the model which caused the enum to be set to its default value. I decided to make the property nullable to test whether the property was being set to the default value because no value was set or because it was somehow receiving the default value and discovered that the binding started working. I then reverted the change and unregistered the HybridModelBinderApplicationModelConvention to use the default model binding and saw that value was set properly. I then tested with the hybrid model binder again, but changed the request to an HTTP POST rather than a GET and it worked properly.

So, it seems there is an issue with the hybrid model binder with Enums when the values are sent via the QueryString.
