* Test namespace cleanup
* Add recognication for RenderFragment in tag helpers
* Remove dead code from node writers
* refactor type check
* Continue to treat child content as a delegate in codegen
* Add extension to enumerate child content
* Reorganize code generation tests
These were growing a bit disorganized, and weren't really result in good
code reuse.
* fix test base class
* Add some child-content tests
* Add an explicit node for ChildContent
Adds a strongly typed node to represent a 'ChildContent' and what it
contains. This allows us to simplify the code generation path,
detect/processes more issues in IR passes, and will be essential for
supporting multiple child content.
* Ignore ChildContent in components when it's just whitespace
* Add diagnostic for duplicate child content
* Add support for explicit child content elements
Precursor to support for multiple child content items
* Add support for multiple child-content elements
* Change delegate signature for RenderFragment<T>
* Clean up Tag Helper constants
* Allow RenderFragment<T> as a child content
* Allow renaming the template parameter
* Improve error message for invalid child content
* Add diagnostic for repeated child content parameter names
- Prior to this we had a `BackgroundDocumentGenerator` that would constantly be updating generated code containers. With this changes we've changed the details in how a `GeneratedCodeContainer` can be mutated. It can now be touched from any thread and is updated when an underlying `DocumentSnapshot` has available content. However, if a generated output comes through that's older then the last seen output we no-op.
- Removed `BackgroundDocumentGenerator` SetOutput logic.
- Updated tests to react to new behavior of `GetGeneratedOutputAsync`.
- Added new test to verify getting generated output results in the setting of the host documents output.
Currently MVC is still running the IActionConstraint implementations for
features that we've already moved into the routing layer. This has a
significant perf cost associated with, and so we want to skip it because
it's redundant. However if anyone has implemented their own
`IActionConstraint`-based features, they still need to just work.
This change takes the approach of skipping the action constraint phase
at runtime unless we see something 'unknown'. This is an all or nothing
choice, and will run action constraints if **any** action constraint we
don't special case exists. This is the most compatible behavior (running
redundant constraints) when the application is using constraints that
the developer implemented.
Another approach I considered was to eliminate these constraints as part
of the process of building ADs. I don't think that's ideal because
people have written code that introspects action constraints. We should
consider something like this in 3.0.
