ActionBindingContext
This change replaces IScopedInstance<T> in favor or IActionContextAccessor
and IActionBindingContextAccessor. In the spirit of IHttpContextAccessor,
these are both singletons which use AsyncLocal for storage.
This change allows the invoker factory to be cached which results in some
significant perf gains.
This is the first step is some more refactorings to come in the future
with the goal of making MVC less monolythic. This makes the core of MVC
more reusable and more in line with the design of other vNext platform
components.
With this change, Mvc.Core contains just the minimal guts needed to build
a working app.
- Action Discovery
- Action Invoker
- Filters
- ObjectResult
- Model Metadata
- Model Binding
- Formatters
- Validation System
And yes, we are aware of the irony of 'minimal MVC' not including the view
system. The idea is that this is the kernel of an MVC app, and anything
real is layered on top.
The most noticable impact of this change is that MvcOptions has been blown
apart into more managable chunks. See the various ConfigureMvc*** methods.
The new Mvc.Extensions package is a placeholder while we evaluate and tune
the new definitions. Expect more changes as features are move to their own
packages, and in some case their own repositories.
For now there is no experience to bootstrap an Mvc.Core app. That's coming
next.
