Deprecate UWP (#4686)

CHANGELOG.md

@@ -7,6 +7,7 @@
 - Spans and Transactions now implement `IDisposable` so that they can be used with `using` statements/declarations that will automatically finish the span with a status of OK when it passes out of scope, if it has not already been finished, to be consistent with `Activity` classes when using OpenTelemetry ([#4627](https://github.com/getsentry/sentry-dotnet/pull/4627))
 - SpanTracer and TransactionTracer are still public but these are now `sealed` (see also [#4627](https://github.com/getsentry/sentry-dotnet/pull/4627))
 - CaptureFeedback now returns a `SentryId` and a `CaptureFeedbackResult` out parameter that indicate whether feedback was captured successfully and what the reason for failure was otherwise ([#4613](https://github.com/getsentry/sentry-dotnet/pull/4613))
+- UWP support has been dropped. Future efforts will likely focus on WinUI 3, in line with Microsoft's recommendations for building Windows UI apps. ([#4686](https://github.com/getsentry/sentry-dotnet/pull/4686))
 - The _Structured Logs_ APIs are now stable: removed `Experimental` from `SentryOptions` ([#4699](https://github.com/getsentry/sentry-dotnet/pull/4699))
