We want this change to avoid MVC eagerly reading the form. This is good
for general perf and also for scenarios where you want read the body
yourself (large file uploads).
We DO have scenarios where you want to configure the value providers
per-request or also to change the limits on the value providers (form) so
it's worth keeping these around on the context.
- #4116
- generalize rules for `ModelMetadata` creation; minimize metadata changes when Model is updated
- down to a single special case in VDD for `Nullable<T>`
- note existing functional tests did not need to change
- remove `ViewDataDictionary(ViewDataDictionary, object)` constructor; use `new VDD<object>(source, model)`
- allow all `Model` assignments in a view component
- copy-constructed VDD in `ViewComponentContext` previously preserved the source's declared type
nits:
- do not call `virtual SetModel()` method from constructor; now mostly redundant
- logic in copy constructor and `SetModel()` is consistent but different enough to keep code separate
- add some missing doc comments
- fix doc comment property versus type confusion; never need to specify `ViewDataDictionary.` prefix
- fix a few `TemplateBuilder` comments and remove unnecessary `model: null` argument to VDD constructor
* Added ViewComponentFeture and ViewComponentFeatureProvider to perform view component discovery.
* Changed view component discovery to use application parts.
* Changed ViewComponentDescriptorProvider to make use of Application parts.
* Added AddViewComponentsAsServices method on IMvcBuilder that performs view component
discovery through the ApplicationPartManager and registers those view components as
services in the service collection. Assemblies should be added to the ApplicationPartManager
in order to discover view components in them in them.
This change separates model binding into IModelBinderProvider (decides
which binder to use) and IModelBinder (does binding). The
IModelBinderFactory is a new services with coordinates the creation of
model binders.
- Simplify things that used to rely on HtmlTextWriter. This behavior is
now the default.
- Simplify a whole mess of Razor TextWriter code.
- Integration test for merging of TagHelper buffers back into the 'main'
buffer.
- #3482
- see new tests; many failed without fixes in the product code
- add support for binding `IFormFileCollection` properties
- make `FormFileModelBinder` / `HeaderModelBinder` collection handling consistent w/ `GenericModelBinder`++
- see also dupe bug #4129 which describes some of the prior inconsistencies
- add checks around creating collections and leaving non-top-level collections `null` (not empty)
- move smarts down to `ModelBindingHelper.GetCompatibleCollection<T>()` (was `ConvertValuesToCollectionType<T>()`)
- add `ModelBindingHelper.CanGetCompatibleCollection()`
- add fallback for cases like `public IEnumerable<T> Property { get; set; } = new T[0];`
- #4193
- allow `Exception`s while activating collections to propagate
- part of #4181
- `CollectionModelBinder` no longer creates an instance to check if it can create an instance
- not a complete fix since it still creates unnecessary intermediate lists
nits:
- correct a few existing test names since nothing is not the same as `ModelBindingResult.Failed()`
- remove a couple of unnecessary `return` statements
- correct stale "optimized" comments
- explicit `(string)`
- aspnet/Coherence-Signed#187
- remove `<RootNamespace>` settings but maintain other unique aspects e.g. `<DnxInvisibleContent ... />`
- in a few cases, standardize on VS version `14.0` and not something more specific
