IActionConstraint follows a provider model similar to filters. The
attributes that go on actions/controllers can be simple metadata markers,
the 'real' constraint is provided by a set of configurable providers. In
general the simplest thing to do is to be both an
IActionConstraintMetadata and IActionConstraint, and then the default
provider will take care of you.
IActionConstraint now has stages based on the Order property. Each group
of constraints with the same Order will run together on the set of
actions. This process is repeated for each value of Order until we run out
of actions or run out of constraints.
The IActionConstraint interface is beefier than the equivalent in legacy
MVC. This is to support cooperative coding between sets of constraints
that know about each other. See the changes in the sample, which implement
webapi-style overloading.
1. Added a new AttributeRouteInfo class to store all the information for
actions that are attribute routed.
2. Added a new ReflectedAttributeRouteModel class to store all the information
related to attribute routes in the ReflectedApplicationModel.
3. Refactored ReflectedControllerModel and ReflectedActionModel to use ReflectedAttributeRouteModel
instead of just the attribute route template.
4. Refactored ReflectedActionDescriptorProvider to use AttributeRouteInfo and ReflectedAttributeRouteModel
instead of just the route template.
5. Added a CombineReflectedAttributeRouteModel method in ReflectedAttributeRouteModel that handles
combining two ReflectedAttributeRouteModel instances.
6. Removed the AttributeRouteTemplate class and moved the methods for combining attribute routes to the
ReflectedAttributeRouteModel class.
7. Added unit tests for ReflectedActionModel and ReflectedControllerModel that
cover the usage of AttributeRouteInfo.
8. Added unit tests for CombineReflectedAttributeRouteModel.
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
