### Root Cause BlazorWebViewTests.Startup.cs uses nullable reference annotations (?), but the project does not enable nullable annotations. This caused CS8632 errors, and warnings are treated as errors. ### Cause PR #35053 ### Fix Added #nullable enable at the top of BlazorWebViewTests.Startup.cs. This follows the existing per-file convention and avoids enabling nullable annotations for the entire project. The Windows device-test build now passes successfully.

<!-- Please let the below note in for people that find this PR --> > [!NOTE] > Are you waiting for the changes in this PR to be merged? > It would be very helpful if you could [test the resulting artifacts](https://github.com/dotnet/maui/wiki/Testing-PR-Builds) from this PR and let us know in a comment if this change resolves your issue. Thank you! ## What's Coming This draft promotes the current `inflight/candidate` contents into `main` for the .NET 10 SR11 (`10.0.110`) candidate cycle. ## Candidate Snapshot - Initial source: `inflight/current`, followed by candidate-specific stabilization and approved backports - Rebased onto `main`: [`b96aa036`](b96aa03) - Current candidate head: [`b643a7e3`](b643a7e) - Final candidate commits relative to `main`: [111 commits](b96aa03...inflight/candidate) - Rebase accounting: all 111 pre-rebase commits map exactly to 111 rebased commits, with no modified, dropped, or added patches - Patch version: `110` - PR #37033 remains intentionally excluded because it merged into `inflight/current` after the initial candidate cut. ## Stabilization Since the Initial Cut - #37669 fixes the MauiBlazorWebView device-test build. - #37672 reverts unstable iOS and Mac Catalyst leak tests. - #37810 reverts the iOS wrapped-scroll-content large-title change. - #37837 completes iOS `ScrollView` requests inside collapsed branches. - #37438 updates the first set of candidate test failures. - #38021 fixes the Windows `ContentPresenter` device-test regression; its patch is now supplied by `main`. - #38096 reverts the Accelerometer weak-event change. - #38126 backports the BlazorWebView and HybridWebView fixes. - #38028 updates the remaining candidate test failures and stale iOS snapshots. ## Rebase Validation - [x] Commit accounting: 111 exact mappings with no modified, dropped, or added patches - [x] Independent reference merge and rebased branch have the identical tree ID `3e10281363c889cbafd4de790911efb0ae365e2a` - [x] BuildTasks succeeds with 0 warnings and 0 errors across the restored Android, iOS, Mac Catalyst, and .NET targets - [x] All 39 focused `ScrollViewUnitTests` pass - [x] No merge commits, conflict markers, or new whitespace warnings; the 26 existing whitespace warnings remain unchanged - [ ] Post-rebase `maui-pr`, `maui-pr-devicetests`, and `maui-pr-uitests` runs complete - [ ] Candidate-only build and test failures triaged - [ ] Release-readiness assessment completed This PR remains a draft while candidate validation and stabilization continue.

Root Cause
BlazorWebViewTests.Startup.cs uses nullable reference annotations (?), but the project does not enable nullable annotations. This caused CS8632 errors, and warnings are treated as errors.
Cause PR
#35053
Fix
Added #nullable enable at the top of BlazorWebViewTests.Startup.cs.
This follows the existing per-file convention and avoids enabling nullable annotations for the entire project. The Windows device-test build now passes successfully.
