Roadmap Progress - July and August 2023 updates

[pchaurasia14]

Below are the updates on 2023 Roadmap deliverables -

Modernization

Area	Update
Win11 Theming	We are currently awaiting the finalization of some cross-team dependencies by our partner teams before we can make further progress on this. We are working towards drafting the spec document for this. We will share more details as soon as we have them.
New control - FolderBrowserDialog	Feature merge is completed 🎉🎉. Sample application and tests are available as well.
Nullability annotations	Based on community feedback, the plan for Nullability annotations support is available here. Ready for community contributions.
Hardware acceleration in RDP	We are happy to announce that we've also merged the PR for enabling hardware acceleration in RDP. This would enable applications on RDP to take advantage of hardware acceleration capability (improved frames/second support, smoother animations, use of video memory, etc.) if the underlying system supports it. Our testing on sample applications which uses animations showed an improvement of 10-30% sustained frame rate when running over RDP. To enable the feature, you need to specify an appcontext switch(System.Windows.Media.IsHardwareAccelerationEnabledForRdp) in either .csproj or *.runtimeconfig.json . Do try this feature out and provide us with your feedback.

Infrastructure upgrades

Area	Update
Test Automation	We have enabled unit testing as well, using build pipelines that are already capable of executing DRTs (DRT means "developer regression tests" -- these are tests that check the basics are not broken) example, microsuites, and feature tests. Special thanks to @hughbe for starting the process of adding unit tests to the repository. Moving forward, we would also concentrate on raising the project's unit test count to enable improved coverage and, as a result, more confidence in problem fixes. These tests runs will be scheduled at regular intervals rather than on each build because it takes a few days to execute all of the microsuites and feature tests. Unit tests and DRTs will continue to run on every build.
Test Migration	Majority for feature tests and microsuites are now available in test repo (~ 80% completed) Few areas that are remaining have a higher amount on infrastructure dependency, hence we would migrate them as and when we incorporate changes to those feature areas. - UI Automation (~ 95) - 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) You can follow our progress overall in this project.
