- no more `IHtmlHelper<object>` in `DefaultDisplayTemplates` and also no
need for `ViewDataDictionary<object>` in a few places
- mostly removals from `IHtmlHelper<TModel>` but did cleanup comments and
add `[NotNull]` for `DisplayFor()`, `DisplayNameFor()`,
`DisplayNameForInnerType()`, and `LabelFor()`
- also add `[NotNull]` for `this` and `Expression` parameters in some
extension methods
We'll create a scoped service provider if the middleware that does it
isn't there.
We resolve all of our stuff from the scoped service provider, allowing
users to plug in any scoped things they want.
Ported UrlHelper to be a scoped service.
- move `DynamicObject` derivation up to new `DynamicViewData` class, fixing [WebFx-169](http://projectk-tc:8080/browse/WEBFX-169)
- avoid direct `_data` lookup in previous `TryGetMember()`, fixing [#118](https://github.com/aspnet/WebFx/issues/118)
- rename ViewData -> ViewDataDictionary
Also
- flesh out `IDictionary<string, object>` implementation in `ViewData`
- provide `ViewData` copy constructor that allows TModel to change
- remove `TryGetIndex()` and `TrySetIndex()` implementations; use `ViewData[]` instead
- restore `ViewContext.ViewBag` from legacy MVC
Modified ModelState to only ever be created on the ActionContext and then plumbed/exposed it on ViewData and Controller. This will enable: ActionFilterContext's will have access to ModelState via its ActionContext member, allow HTMLHelpers to access ModelState via ViewData, and unify the locations of "source" model state. In the old world we used to copy/replace/instantiate new model state all over unnecessarily.
1. Areas defined by the Area attribute
2. Areas are a routeconstraint on the actiondescriptor
3. Areas find pages through route values
Other changes:
1. Remove Path from ActionDescriptor - It doesn't make sense with this change
2. Add sample Area
- use Microsoft.AspNet.Mvc.Rendering namespace throughout assembly
Also
- move `IdAttributeDotReplacement` from `TagBuilder` to `HtmlHelper`
- remove commented-out code in `HtmlHelper`
- use `var` and `[NotNull]` more
- `String` -> `string`
- correct Resources references; add missing resources
This follows a similar pattern to html helpers - a minimal basis interface
that performs the main functionality, and a set of extension methods that
make up the rich API.
