To use it in your app, install the [Microsoft.WindowsAppSDK 1.8.260529003 NuGet package](https://www.nuget.org/packages/Microsoft.WindowsAppSDK/1.8.260529003). 1.8.9 is a stable servicing release for 1.8. The WinUI changes in this release are two reliability fixes: - Fixed a memory leak in `ItemsRepeater` where recycled elements were never garbage collected due to a reference cycle through the `RecyclePool`, which could also cause crashes in `InvalidateChildrenMeasure`. - Fixed a potential crash when releasing touch contacts in a `ScrollViewer` before scrolling. For the full set of changes, see the [Windows App SDK 1.8.9 release notes](https://github.com/microsoft/WindowsAppSDK/releases/tag/v1.8.9). Try it out - Install the [Microsoft.WindowsAppSDK 1.8.260529003 NuGet package](https://www.nuget.org/packages/Microsoft.WindowsAppSDK/1.8.260529003). - Download and update..."},"evidence_pages":[],"related_signals":[{"id":"432f6193-5e4c-4f16-bbe0-6a87ef01916f","url":"https://onlylabs.fyi/signals/432f6193-5e4c-4f16-bbe0-6a87ef01916f","source_url":"https://github.com/microsoft/accessibility-insights-web/releases/tag/web%402.47.0","title":"microsoft/accessibility-insights-web web@2.47.0","context":"microsoft/accessibility-insights-web","kind":{"key":"release","label":"Release"},"org":{"slug":"microsoft","name":"Microsoft","category":"frontier-lab"},"occurred_at":"2026-06-11T06:37:28+00:00","first_seen_at":"2026-06-11T07:01:13.026392+00:00","date_source":"source"},{"id":"afc38512-1630-4041-9fb3-39414d8d2b0a","url":"https://onlylabs.fyi/signals/afc38512-1630-4041-9fb3-39414d8d2b0a","source_url":"https://github.com/microsoft/content-processing-solution-accelerator/releases/tag/v2.1.1","title":"microsoft/content-processing-solution-accelerator v2.1.1","context":"microsoft/content-processing-solution-accelerator","kind":{"key":"release","label":"Release"},"org":{"slug":"microsoft","name":"Microsoft","category":"frontier-lab"},"occurred_at":"2026-06-11T06:06:46+00:00","first_seen_at":"2026-06-11T07:01:13.026392+00:00","date_source":"source"},{"id":"5271de48-ab99-4310-8d2c-174188866071","url":"https://onlylabs.fyi/signals/5271de48-ab99-4310-8d2c-174188866071","source_url":"https://github.com/microsoft/CsWin32/releases/tag/v0.3.287","title":"microsoft/CsWin32 v0.3.287","context":"microsoft/CsWin32","kind":{"key":"release","label":"Release"},"org":{"slug":"microsoft","name":"Microsoft","category":"frontier-lab"},"occurred_at":"2026-06-11T04:22:28+00:00","first_seen_at":"2026-06-11T07:01:13.026392+00:00","date_source":"source"},{"id":"6adcd577-5563-4fd8-85dd-268919492cf0","url":"https://onlylabs.fyi/signals/6adcd577-5563-4fd8-85dd-268919492cf0","source_url":"https://github.com/microsoft/sqltoolsservice/releases/tag/6.0.20260610.1","title":"microsoft/sqltoolsservice 6.0.20260610.1","context":"microsoft/sqltoolsservice","kind":{"key":"release","label":"Release"},"org":{"slug":"microsoft","name":"Microsoft","category":"frontier-lab"},"occurred_at":"2026-06-10T23:57:44+00:00","first_seen_at":"2026-06-11T07:01:13.026392+00:00","date_source":"source"},{"id":"7557f4d3-5544-422b-b39d-1e668cb0dfa5","url":"https://onlylabs.fyi/signals/7557f4d3-5544-422b-b39d-1e668cb0dfa5","source_url":"https://github.com/microsoft/agent-framework/releases/tag/dotnet-1.10.0","title":"microsoft/agent-framework dotnet-1.10.0","context":"microsoft/agent-framework","kind":{"key":"release","label":"Release"},"org":{"slug":"microsoft","name":"Microsoft","category":"frontier-lab"},"occurred_at":"2026-06-10T17:50:17+00:00","first_seen_at":"2026-06-11T07:01:13.026392+00:00","date_source":"source"},{"id":"e18f0e7d-b1df-421e-a845-19cad8151a11","url":"https://onlylabs.fyi/signals/e18f0e7d-b1df-421e-a845-19cad8151a11","source_url":"https://github.com/microsoft/ai4s-jobq/releases/tag/v3.13.1","title":"microsoft/ai4s-jobq v3.13.1","context":"microsoft/ai4s-jobq","kind":{"key":"release","label":"Release"},"org":{"slug":"microsoft","name":"Microsoft","category":"frontier-lab"},"occurred_at":"2026-06-10T17:19:31+00:00","first_seen_at":"2026-06-11T07:01:13.026392+00:00","date_source":"source"}]}
