- #8180
- add an error when binding fails for top-level model
- same case as when MVC creates "default" / empty model i.e. `ParameterBinder` can't detect this
- update `CollectionModelBinder` subclasses and the various providers as well
- controlled by existing `MvcOptions.AllowValidatingTopLevelNodes` option
smaller issue:
- change `ModelBinding_MissingBindRequiredMember` resource to mention parameters too
- #7562 part 2
- add `OriginalModelName` to `ModelBindingContext`
nit: take VS suggestions, mostly to inline collection initialization in `FormFileModelBinderTest`
Change tokens can call into your code IMMEDIATELY when you subscribe. I
reviewed our other usage of ChangeToken.OnChange in MVC and everything
looks good.
Currently MVC is still running the IActionConstraint implementations for
features that we've already moved into the routing layer. This has a
significant perf cost associated with, and so we want to skip it because
it's redundant. However if anyone has implemented their own
`IActionConstraint`-based features, they still need to just work.
This change takes the approach of skipping the action constraint phase
at runtime unless we see something 'unknown'. This is an all or nothing
choice, and will run action constraints if **any** action constraint we
don't special case exists. This is the most compatible behavior (running
redundant constraints) when the application is using constraints that
the developer implemented.
Another approach I considered was to eliminate these constraints as part
of the process of building ADs. I don't think that's ideal because
people have written code that introspects action constraints. We should
consider something like this in 3.0.
I think something that was meant to be revisited in a PR got left
behing. I found this while fixing aspnet/Routing#772 and it seems worth
addressing.
This change removes the hardcoding of action/controller/area in the
data source, and corrects the behavior of required route values when
they aren't in that set.
Both UnsupportedContentTypeFilter and ModelStateInvalidFilter use ModelState to
determine the response. UnsupportedContentTypeFilter returns a more specific
response and should execute earlier than the latter filter.
