- #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 TagHelperFeature and TagHelperFeatureProvider to perform tag helper discovery.
* Changed tag helper discovery to use application parts when using tag helpers as services.
* Added FeatureTagHelperTypeResolver to resolve tag helper type definitions from the list of application parts.
* Added AddTagHelpersAsServices extension method on IMvcBuilder and IMvcCoreBuilder that
performs tag helper discovery through the ApplicationPartManager and registers those tag helpers as
services in the service collection. Assemblies should be added to the ApplicationPartManager
in order to discover tag helpers in them in them. The @addTagHelper directive is still required on
Razor pages to indicate what tag helpers to use.
- remove duplicate `null` checks in `ViewDataDictionary` constructors
- correct a couple of code comments
- use a `public` constructor for `ViewDataDictionary` in `ViewExecutor`
* Remove IAssemblyProvider.
* Remove DefaultAssemblyProvider in favor of DefaultAssemblyPartDiscoveryProvider.
* Update AddMvcDnx to add the list of DNX discovered assemblies to the list of application parts.
* 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.
* Added ControllerFeature and ControllerFeatureProvider to perform controller discovery.
* Changed controller discovery to use application parts.
* Changed ControllerActionDescriptorProvider to make use of Application parts.
* Simplified AddControllerAsServices to not accept any parameter and perform
controller discovery through the ApplicationPartManager in the IMvcBuilder
and IMvcCoreBuilder. Assemblies should be added to the ApplicationPartManager
in order to discover controllers in them.
This change renames IPropertyBindingPredicateProvider to
IPropertyFilterProvider. The changes here are mostly renames of
parameters/variables from predicate -> propertyFilter. I did a
find+replace and left the term 'predicate' in some of the docs because it
refers to a predicate in the abstract sense.
This change also simplifies BindAttribute and removes support for type
activation.
This commit introduces application parts as a concept on MVC.
An application part is an abstraction that allows you to expose some
feature or corncern in a way that is decoupled from their underlying source.
Examples of this include types in an assembly, emdeded resources, files on
disk etc.
Application parts are configured during startup by adding or removing them from
the application part manager available as part of IMvcBuilder and IMvcCoreBuilder.
The application part manager provides the ability to populate features from the
list of available application parts by using a list of application feature providers.
Application feature providers are responsible for populating a given feature given a
list of application parts.
Examples of application providers can be a ControllerFeatureProvider
that goes through the list of application parts, sees which one of those parts exposes types,
determines which of those types are controller types, and adds them to a ControllerFeature
that holds a list of all the types that will be considered controllers in the application.
* Introduce ControllerAttribute and use it to mark base classes as controllers.
* Changed rules for controller discovery to:
* All controller types must be public, concrete, non open generic types.
* NotController attribute is not applied to any type oif the hierarchy.
* The type name ends with controller.
* Controller attribute is applied to the type or to one of its ancestors.
* Moved instantiation of tag helpers into DefaultTagHelperActivator.
* Introduced ITagHelperFactory for handling the setup of new tag helper instances.
Just a safety measure in case anything evades our 'flattening'. I don't
have any evidence that we're failing to clear something, but we want this
here as a safeguard.
