…#4935) (#4949) * Reapply "Delegate to OS RegFreeWinRT when available (>=24H1) (#4728)" (#4935) This reverts commit c088336. * Added missing dependencies for OAuth2ManagerTests * Expanded tests * Modified IsSupported with temporary debugging hack to expedite testing. Added local hackery for Architectures=None (but is it needed?) * Removed debug hackery * Test fixes * More test fiddling * Microsoft.Windows.BadgeNotifications.Projection project is missing a build-order dependency on WindowsAppRuntime_DLL so depending on timing and beefy machine it can try to build before the dependency is built and boom :-( * Removed redundant Import * Fixed bad merge * Fixed WinAppSDK framework package family name construction in GetFrameworkPackageFamilyName() [MddBootstrap.cpp]. This is used in production when delegating to OS DynDep but not when using WinAppSDK DynDep (and test support used different codepath). That's why test packages with blah-major.minor... package names worked in test and on Win10 but not when delegating to OS DynDep on Win11. Added additional test tools to aid verification and debugging (now and in any future changes). * Fixed DevCheck -CheckDependencies if packages.config has no <package> elements. Ran DevCheck -SyncDependencies to update stale dependencies * Fix test framework package Name from name-major.minor to name.major.minor * Workaround Windows bug https://task.ms/54835001 where IsPackage*ReadyOrNewerAvailable() doesn't correctly handle ProcessorArchitectureFilter=None * Ran devcheck -syncdependencies * Fixed failing PackageManagementTests * Updated dependnecies via DevCheck -SyncDependencies. Removed unused Microsoft.Windows.SDK.BuildTools and Microsoft.WindowsAppSDK references in WindowsAppRuntime_UniversalBGTaskDLL's packages.config. Removed dead readme.txt in WindowsAppRuntime_UniversalBGTaskDLL projectdir (artifact of VS File/NewProject...). * Updated link to latest SDK rev * Fixed dependencies (syntax and usage * Put WindowsAppRuntime_UniversalBGTaskDLL back to what's in main. No idea why that works but changing it -- in what should be innocuous ways -- breaks local + pipeline builds. Deferring that problem to Will Thant in its own right (not relevant to my changes) * Fixed hardcoded versions in OAuthTestApp.vcxproj (wasn't using version macro) * Fixed more bad projects - Import Microsoft.Cpp.Default.props not at the top, .. pathing to nugets and hardwired nuget versions * Fixed WindowsAppRuntime_UniversalBGTaskDLL - Import Microsoft.Cpp.Default.props not at top of file, not using $(NugetPackageDirectory) for pathing to nugets, hardwired versions for nugets, unnecessary Microsoft.WindowsAppSDK in packages.config * Added -ShowSystemInfo (default=$true) to Testall so test run output includes basic system info * Fixed up test Main+Singleton+DDLM naming/constants * Fixed bug in package name constant * Added missing project dependencies. Updated ConfigurationManager to build test packages on ARM64 too (some were only build for x64|x86) * Fixed bad merge * Fixed a bad merge * Removed temporary debugging code * Some test packages lacked ARM64 support, plus those and others weren't getting built for ARM64. And some projects built not-ARM64 for ARM64. Mostly fixed. Some test projects lack ARM64 support but not touched as not blocking here and overdue already; they can (and will) be handled in a separate follow up effort * Fixed one more ARM configuration manager misconfiguration --------- Co-authored-by: Kyaw Thant <48363984+kythant@users.noreply.github.com>
