Even odder was that I could provide a custom value provider but not a model binder.\r\n\r\nI'd expect them to both be flexible and allow for custom validators/binders/value providers OR have neither and rely on a consumer to modify what's on the control prior to calling into them.\r\n\r\nOddities:\r\n- `TryUpdateModelAsync` gives you the ability to provide an `IValueProvider` to update with but not an `IModelBinder`.\r\n- `TryValidateModel` doesn't allow you to provide an IModelValidator of any sort."}}
