- `DefaultInlineConstraintResolver` has no need of a `IServiceProvider`
nits:
- add doc comments for changed `DefaultInlineConstraintResolver` ctor
- let VS add a dev server port to sample's .kproj
- add debugSettings.json and .vs/ to .gitignore
This is useful for a variety of interesting scenarios in link generation
where a default value doesn't appear in the route template as a parameter.
This can be used to implement the desired behavior for areas - where the
'area' key is sticky.
Moving out Default Handler and IInlineConstraintResolver from RouteCollection.
These are moved to a new interface IRouteBuilder, (instead of an IInlineConstraintResolver, it takes in an IServiceProvider).
This means all RouteCollectionExtensions are moved to RouteBuilderExtensions.
