Roadmap progress - April 2023

[pchaurasia14]

Below are the updates on 2023 Roadmap deliverables -

Modernization

Area	Update
Win11 Theming	We have been busy with planning the next steps on delivering this. Due to more complex nature of the feature, this is taking longer than what we originally estimated. Activities such as scoping the full set of features, dependencies on other stakeholders, testing plan are currently under works. While we are hoping, we can get started with this feature implementation, this feature may not make it in time for .NET 8 (possibly .NET 9). It is still too early to comment on the exact timeline due to higher number of unknowns. We will let the community know as soon as we have finalized the concrete steps on this. Reiterating that planning investments upfront should minimize the risk of unexpected setbacks and ensure that we are moving in the right direction. We will post our analysis soon
New control - FolderBrowserDialog	API proposal for FolderBrowserDialog is approved 🎊 (Thank you so much @miloush !!) We have already started adding some basic tests for the new control. We would be adding more tests to ensure that the refactoring has not disturbed the behavior of existing controls/hierarchy.
Nullability annotations	- No change in the plan. Nullability annotations in System.Windows.Input.Manipulations under progress. However this does NOT block community contributions on other assemblies

Infrastructure upgrades

Area	Update
Test Automation	Build pipelines are already running DRTs (DRT means "developer regression tests" -- these are tests that check the basics are not broken). See example. Microsuites (a subset of feature tests) and feature tests themselves (the bulk of all WPF tests) on public build pipelines currently under progress. While the basic infrastructure is almost ready, the completion of this feature is also dependent on the number of tests that are available in the public domain. Additionally, we are working towards showing better test results on the PRs
Test Migration	Migration for feature tests and microsuites are in progress (~ 35% completed) - ElementLayout ( ~ 1.3K) - PR - DataServices (~ 470) - PR - Animation (~ 1.7K) - PR - XAML (~ 2.2K) - PR - Graphics (~ 35) - PR - AppModel (~ 134) - PR - ElementServices (~ 5.1K) - in progress - Controls (~ 5K) - in progress Number of tests are indicative of total number of tests made available (including disabled tests) We're migrating feature tests and microsuites progressively, working on the most active areas first. The areas listed above are the first ones -- you can follow our progress overall in this project.

Issues/ PRs

Area	Update
Community contributions (PRs)	Following community PRs have been merged for April - Fix NullReferenceException in new ContentWrapperAttribute(null).GetHashCode #215 (Thanks @hughbe) - Fix bug in XamlTypeInvoker.GetAddMethod if there is no such match #211 (Thanks @hughbe) - Fix NullReferenceException in XamlType.Equals/XamlType.GetHashCode #220 (Thanks @hughbe) - Cleanup following replacing resource constants with properties. #7691 (Thanks @hughbe) - Replace String.CompareOrdinal to string.Equals in KnownTypes Part 2 #7680 (Thanks @lindexi) - optimistic TrackValue check, supporting not anymore connected columns #6553 (Thanks @leo-schick) - Simplify dwrite.dll loading process #6538 (Thanks @kant2002) - Fixing validation adorner for not yet visible controls #1167 (Thanks @batzen) For this month's test pass run, we were able to close out few very old PRs. We would like to express our sincerest gratitude to all the contributors who have helped improve WPF over the years, despite having to wait for extended periods to have their pull requests merged. We intend to continue maintaining a steady rate of 6/8 PRs on every test run.
Issues	We closed issues which did not have proper repro samples and those associated with the PR
