* Update ncrunch config.
* Tidy up reflection and multi-binding APIs:
- Move `BindingBase` and `MultiBinding` into Avalonia.Base
- `BindingBase` becomes a true base class for all bindings, and contains only the `Instance` method
- Properties common between reflection and compiled bindings are moved into `StandardBindingBase`
- `Binding` is moved to Avalonia.Base and renamed to `ReflectionBinding`
- A compatibility shim for `Binding` remains in Avalonia.Markup
- Remove `IBinding` and `IBinding2`
- Remove `ITreeDataTemplate's usage of `InstancedBinding`
- Remove `NativeMenuBarPresenter`s usage of `InstancedBinding`
- Remove `InstancedBinding` as it is now unused
This required an update to the DataGrid submodule: cell data validation has been temporarily removed as this used `InstancedBinding`.
* `Instance()` => `CreateInstance()`.
The use of "Instance" as a verb is quite unusual apparently ;)
* Seal classes where appropriate.
* Seal classes where appropriate.
* Remove `StandardBindingBase`.
Simply duplicate the members in reflection and compiled binding classes.
* Delete deleted submodule directory.
* Add missing attribute.
Fixes compile error.
* Fix reference to removed class.
* Update suppressions.
* Update ncrunch config.
* Fix test naming.
* Add BindingExpressionGrammar tests.
We only had tests for the error states, and that was named incorrectly.
* Parse null-conditionals in bindings.
* Initial impl of null conditionals in binding path.
Fixes#17029.
* Ensure that nothing is logged.
* Make "?." work when binding to methods.
* Don't add a new public API.
And add a comment reminding us to make this class internal for 12.0.
* Use existing method.
* Try to infer DataContext type from #named binding nodes
* Try to infer DataContext type from $parent binding nodes
* Use new syntax in the repo (Rider still marks it as an error)
* Add tests ensuring type casing still works
* Fix $parent regression
* Make new tests StringSyntax compatible
* Add InheritDataTypeFromAttribute and use it in TemplateBinding
* Add failing tests for TemplateBinding depending on a scope
* Update XamlX and RoslynTypeSystem
* Add missing interface implementations
* Improve errors readability in XamlAvaloniaPropertyHelper
* Use more specific TryGetCorrectlyTypedValue overloads
* Finally, respect InheritDataTypeFromAttribute in the AvaloniaProperty parser
* Add some docs
* Output better exception
* Update XamlX
* Add missing docs
* Add attribute to well known types
* Add Correctly_Resolve_TemplateBinding_In_Theme_Detached_Template test and fix ColorPicker usage

* Add failing test for #16113.
* Convert delegate to ICommand in style setter.
When compiling a binding to e.g. `Button.Command` in a style `Setter`, we were not converting `XamlIlClrMethodPathElementNode` to `XamlIlClrMethodAsCommandPathElementNode` as we were only testing whether the property that the binding was being assigned to is an `ICommand`.
If we detect that we're assigning the binding to a `Setter.Value` then we need to look in the `Setter.Property` to see check whether the property is an `ICommand` too.
Fixes#16113
* Update ncrunch config.
* WIP: Benchmarks
* Initial refactor of binding infrastructure.
- `ExpressionObserver` has been removed and its functionality merged with `BindingExpression`
- `BindingExpression` handles all types of `BindingMode` itself; doesn't require `BindingOperations.Apply` to set up a separate observable for `TwoWay/`OneWayToSource` bindings
- This allows us to fix some long-standing issues with `OneWayToSource` bindings
- Expression nodes have been refactored
- No longer split between `Avalonia.Base` and `Avalonia.Markup`
- Categorize them according to whether they use reflection or not
A few tests are failing around binding warnings: this is because the next step here is to fix binding warnings.
* Make default binding Source = UnsetProperty.
Null is a theoretically valid value for `Source`; setting it to null shouldn't mean "use the data context".
* Move logging to BindingExpression.
As `BindingExpression` now has enough information to decide when it's appropriate to log an error/warning or not.
Fixes#5762Fixes#9422
* Add compatibility hack for older compiled bindings.
Previously, `CompiledBindingPathBuilder` didn't have a `TemplatedParent` method and instead the XAML compiler rewrite templated parent bindings to be a `$self.TemplateParent` property binding. resulting in extraneous logs.
Add a constructor with an `apiVersion` to `CompiledBindingPathBuilder` which will be used by newer versions of the XAML compiler, and if a usage is detected using an `apiVersion` of 0, then upgrade `$self.TemplatedParent` to use a `TemplatedParentPathElement`.
* Log errors from property accessors.
* Don't log errors for named control bindings...
...on elements which aren't yet rooted.
* Log errors for failed conversions.
* Use consistent wording for binding warnings.
"Could not convert" instead of "Cannot convert".
* Log warnings for converter exceptions.
* Don't convert new TargetTypeConverters each time.
* Added failing test for implicit conversion.
* Support cast operators in compiled bindings.
A bit of a hack as we'd ideally not be using reflection when using compiled bindings.
* This shouldn't be a public API.
Should only be used for tests.
* Make enum/int conversion work.
* Check for SetValue equality after conversion.
And also use "identity equals" where value types and strings use `object.Equals` and reference types use `object.ReferenceEquals`.
* Added ConverterCulture back to bindings.
* Fix merge error.
Removed deleted files from csproj that were re-added due to indentation changes.
* Use BindingExpression directly in ValueStoe.
* Introduce BindingExpressionBase.
And `UntypedBindingExpressionBase`.
* Make TemplateBinding a BindingExpression.
* Make DynamicResource use a BindingExpression.
* WIP: Start exposing a BindingExpression API.
* Finish exposing a BindingExpression API.
* Fix OneTimeBinding.
* Remove unneeded classes/methods.
* Don't call obsolete API.
* Make BindingExpressionBase the public API.
This matches WPF's API.
* Added BindingExpressionBase.UpdateTarget.
* Initial implementation of UpdateSourceTrigger.
* Don't use weak references for values.
If they're boxed values, they can get collected.
* No need for virtual/generic methods here now.
* Reintroduce support for binding anchors.
Turns out these were needed by animations, just our animation system has no unit tests so I missed that fact earlier. Add a basic animation unit test that fails without anchor support, and add binding anchors back in. Currently a private API as I suspect this feature shouldn't be needed outside the framework.
* Include new property in clone.
And add real-life example of `UpdateSourceTrigger=LostFocus` to BindingDemo.
* Fix merge error.
* Updated BindingExpression tests.
- Make them run for both compiled and reflection bindings (found a bunch of tests that fail with compiled bindings)
- Make them not depend on converting the `BindingExpression` to an observable and instead test the end result of the binding on an `AvaloniaObject`
* Fix compiled binding indexer tests.
* Use data validation plugins in PropertyAccessorNode.
Added a warning suppression for now: we may need a separate `DataValidators` list for AOT-friendly plugins.
* Don't separate plugins by reflection.
`DataAnnotationsValidationPlugin` is public and so it can't be moved. No point in moving the others if this one will be in the wrong place.
* Remove unneeded methods.
* Make reflection binding tests use a string.
Convert the `System.Linq.Expression` to a string and then use this, as reflection bindings will always be instanced with a string path.
* Added TODO12 plan for IBinding2.
* Use more specific exception.
* Fix nits from code review.
* Make expression nodes sealed where possible.
* Unsubscribe on Stop, don't re-subscribe.
D'oh.
* Tweak ExpressionNode lists.
Saves a few K in benchmarks and it's a cleaner API.
* Add a pooled option in BindingExpressionGrammar.
Micro-optimization.
* Avoid allocations when enumerating binding plugins.
* Add IBinding2 support to observable bind overloads.
In the case of `TemplateBinding`, the `IObservable<object?>` bind overload is selected by C#. Add an explicit check for an `IBinding2` here to use the more performant code-path.
* Remove disposed binding from ImmediateBindingFrame.
* Added TemplateBinding benchmarks.
* Remove duplicate items.
Seems to have been caused by a merge error.
* Fix exception when closing color picker.
And add tests.
* Don't skip converter when binding to self.
* Don't pass UnsetValue to converters.
This follows WPF behavior.
* Log element name if present.
More useful than just logging the control hash code.
* Respect binding priority.
* Throw on mismatched binding priorities.
We don't want to respect the binding priority in this case as it breaks `TemplateBindings` when the default `LocalValue` priority is passed. Instead make sure that the priority parameter matches that of the expression.
This reverts commit a72765d705.
* Convert to target type in TemplateBinding.
* Short-circuit target type conversion for same types.
* Add diagnostics support to the Avalonia.Build.Tasks
* HostApp and generators build fix
* Diagnostics support in Avalonia XAML
* Support multiple style selector errors at once
* Improve avalonia intrinsics error handling + add tests
* Add CompiledBindings multiple errors tests
* Fix name generator
* Make AvaloniaXamlIlDuplicateSettersChecker a warning
* Fix Style_Parser_Throws_For_Duplicate_Setter test
* Make XamlLoaderUnreachable respect warnings settings
* Add AvaloniaXamlIlStyleValidatorTransformer
* Throw more specific exceptions instead of XamlParseException
* Get rid of XamlXDiagnosticCode to simplify diagnostics code
* Simplify XAML exceptions by avoiding DiagnosticCode in them
* Simplify XamlCompilerDiagnosticsFilter
* Don't use AvaloniaXamlDiagnosticCodes in Avalonia.Generators
* Fix some error handlings in compiler task
* Update editor config for in-solution analysis
* Update XamlX
* Fix missing document path
* Avoid Description field usage
* Add AvaloniaXamlVerboseExceptions property and make exception formatting customizable
* Make Avalonia.NameGenerator not crash if there are XAML errors, members should still be generated
* Update tests/Avalonia.Markup.Xaml.UnitTests/Xaml/StyleIncludeTests.cs
