- HtmlHelper service now needs an `IModelMetadataProvider` instance
- make `GetInputTypeString()` private
- use `TextBox()` and `TextBoxFor()` in MVC sample
- throw if `ExpressionMetadataProvider.FromLambdaExpression()` returns `null`
- `Name()` is a `virtual` instance method to allow useful derivation
- `NameFor()` is an instance method to avoid adding `GetExpressionName()`
to the public surface; either method could be `virtual`
- `NameForModel()` is an extension method because it's not usefully overridden
- use `Name*()` in sample
- 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
- demonstrate `ModelMetadata` is available in a view
Also
- simplify `View()` overloads in `Controller`, pending #110 decisions
- make `Model` in `RazorView<T>` readonly
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
This is as simple as modifying the base class to return task and await the ExecuteAsync method. Also added a piece to the sample project to verify functionality.
