* #19962 Add AXAML Source Information to debug Builds * SimplifyXamlSourceInfo * Add XamlSourceInfo for as many elements as possible * Add tests to confirm XamlSourceInfo is set for all types * Remove property only added for debugging during development * update skipped test so it runs (even though it doesn't yet pass) * Wrap XamlAstNewClrObjectNode instead of XamlAstObjectNode, run transformer late * Remove unsupported value types from the More_Resources_Get_XamlSourceInfo_Set * Fix Document property not being set in runtime parser * Add a dedicated CreateSourceInfo parameter for RuntimeXamlLoaderConfiguration, instead of reusing DesignMode * Inherit real XamlValueWithManipulationNode, move actual manipulation to a separate class * Fix group transformers by unwrapping manipulation nodes first * minor Resource related test change * Update public API as agreed * Add new failing tests for the dictionaries * Fix randomly failing tests, that depend on the test order * Fix assert * Rename AvaloniaXamlResourceTransformer * Emit XamlSourceInfo from AvaloniaXamlResourceTransformer * Rename AvaloniaXamlIlResourceTransformer for consistency * Cleanup comments * Remove XamlSourceInfoValueWithManipulationNode, use standard XamlValueWithManipulationNode * Add new RuntimeXamlLoaderDocument.Document property * Use UriBuilder trick to support unix paths on windows * Add private AttachedProperty for avalonia objects, instead of always using weak table * Fix wrong UriBuilder usage and add more test assets * Fix "Invalid URI" exception --------- Co-authored-by: KimHenrik <kimhenrik@outlook.de> Co-authored-by: Max Katz <maxkatz6@outlook.com>pull/20557/merge
