This change avoids a state machine allocation and a dictionary allocation
on the common case (no bound properties). Ugly? You bet. Worth it? Yeah,
seems worthwhile.
This is worth about 200 bytes/request - about 3% of allocated bytes in a
smallish API scenario.
This change introduces ControllerContext for inside of Controllers, and
controller-specific extensibility points. ControllerContext carries with
it the model binding infrastructure needed to do all of the things that
controllers need to do.
Abstractions - Core MVC extensibility
Controllers - MVC implementations of .Abstractions and supporting
contracts
Infrastructure - General purpose support APIs. Metadata APIs that don't
fit clearly with a feature or with .Abstraction
