Roadmap Progress - May and June 2023 updates

[pchaurasia14]

Below are the updates on 2023 Roadmap deliverables -

Modernization

Area	Update
New control - FolderBrowserDialog	Implementation review and merge is completed 🎉🎉. We have added sample application for FolderBrowserDialog. We have already added few 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.
Win11 Theming	We are in process of completing few proof of concepts with respect to the approach that would enable us to deliver this. We are hoping to get it done by next couple of weeks. 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 you know as soon as we have finalized the concrete steps on this.
Nullability annotations	No change in status. Nullability annotations in System.Windows.Input.Manipulations under progress. However this does NOT block community contributions on other assemblies. You can refer the plan for nullability annotations here.

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. We have fixed few broken tests. Microsuites (a subset of feature tests) and feature tests themselves (the bulk of all WPF tests) on public build pipelines is also enabled. Since the total time to run all the microsuites and feature tests take couple of days, these tests are going to be scheduled at regular intervals rather than on each build. We are working to enable unit tests integration in our repo. This will enable us to start writing unit tests to assert behavior changes. We are also working to improve test results visualization on the PR builds.
Test Migration	Migration for feature tests and microsuites are in progress (~ 70% completed) - ElementServices (~ 5.1K) - PR - Controls (~ 954) - PR - FlowLayout (336 ) - PR - WindowsFormIntegration () -PR - Editing PR - 2D (in progress) - 3D (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.
