with MVC5.
This change removes the behavior in model binding to validate values 'on
the wire' for requiredness instead of the looking at the model. This
restores the behavior of [Required] for model binding to the MVC5
semantics.
Also ensures that when a type is marked as skipped, any sub property which is model bound (and hence a modelstate un validated entry),
is marked as skipped (otherwise it would cause the ModelState to be invalid).
Also fixing a bug in model state dictionary FindKeyWithPrefix was not considering [0] & [0][0] as a valid prefix.
This part of the change removes default value support from ModelBinding.
Updated some unit tests to verify that it does nothing in that case.
Deleted a functional test as it was pure duplication of another
(supported) case where the property has a pre-initialized value.
Covers simple scenario for each model binder.
Covers scenarios mixing a POCO model binder -> Simple Model binder.
This contains tests for
FormCollectionModelBinder
BinderTypeBasedModelBinder
TypeConverterModelBinder
Remainging:
TypeMatchModelBinder
This also adds missing unit test for TypeMatchModelBinder as well.
