Root cause

When the app resumes from a minimized state, the CollectionView on MainPage re-evaluates its bindings. The SelectionChangedCommand fires with a null SelectedProject, calling NavigateToProject(null), which returns null. The AsyncRelayCommand generated by RelayCommand tries to await/check this null Task internally in AwaitAndThrowIfFailed, causing the NullReferenceException.

Description of Change

This pull request makes a minor improvement to the NavigateToProject command in the MainPageModel to ensure it always returns a Task, even when the input is null. This helps maintain consistency and prevents potential issues with null returns.

Thank you!

## Description

Adds a [gh-aw (GitHub Agentic
Workflows)](https://github.github.com/gh-aw/introduction/overview/)
workflow that automatically evaluates test quality on PRs using the
`evaluate-pr-tests` skill.

### What it does

When a PR adds or modifies test files, this workflow:
1. **Checks out the PR branch** (including fork PRs) in a pre-agent step
2. **Runs the `evaluate-pr-tests` skill** via Copilot CLI in a sandboxed
container
3. **Posts the evaluation report** as a PR comment using gh-aw
safe-outputs

### Triggers

| Trigger | When | Fork PR support |
|---------|------|-----------------|
| `pull_request` | Automatic on test file changes (`src/**/tests/**`) |
❌ Blocked by `pre_activation` gate |
| `workflow_dispatch` | Manual — enter PR number | ✅ Works for all PRs |
| `issue_comment` (`/evaluate-tests`) | Comment on PR | ⚠️ Same-repo
only (see Known Limitations) |

### Security model

| Layer | Implementation |
|-------|---------------|
| **gh-aw sandbox** | Agent runs in container with scrubbed credentials,
network firewall |
| **Safe outputs** | Max 1 PR comment per run, content-limited |
| **Checkout without execution** | `steps:` checks out PR code but never
executes workspace scripts |
| **Base branch restoration** | `.github/skills/`,
`.github/instructions/`, `.github/copilot-instructions.md` restored from
base branch after checkout |
| **Fork PR activation gate** | `pull_request` events blocked for forks
via `head.repo.id == repository_id` |
| **Pinned actions** | SHA-pinned `actions/checkout`,
`actions/github-script`, etc. |
| **Minimal permissions** | Each job declares only what it needs |
| **Concurrency** | One evaluation per PR, cancels in-progress |
| **Threat detection** | gh-aw built-in threat detection analyzes agent
output |

### Files added/modified

- `.github/workflows/copilot-evaluate-tests.md` — gh-aw workflow source
- `.github/workflows/copilot-evaluate-tests.lock.yml` — Compiled
workflow (auto-generated by `gh aw compile`)
- `.github/skills/evaluate-pr-tests/scripts/Gather-TestContext.ps1` —
Test context gathering script (binary-safe file download, path traversal
protection)
- `.github/instructions/gh-aw-workflows.instructions.md` — Copilot
instructions for gh-aw development

### Known Limitations

**Fork PR evaluation via `/evaluate-tests` comment is not supported in
v1.** The gh-aw platform inserts a `checkout_pr_branch.cjs` step after
all user steps, which may overwrite base-branch skill files restored for
fork PRs. This is a known gh-aw platform limitation — user steps always
run before platform-generated steps, with no way to insert steps after.

**Workaround:** Use `workflow_dispatch` (Actions UI → "Run workflow" →
enter PR number) to evaluate fork PRs. This trigger bypasses the
platform checkout step entirely and works correctly.

**Related upstream issues:**

## Summary

Enables the copilot-evaluate-tests gh-aw workflow to run on fork PRs by
adding `forks: ["*"]` to the `pull_request` trigger and removing the
fork guard from `Checkout-GhAwPr.ps1`.

## Changes

1. **copilot-evaluate-tests.md**: Added `forks: ["*"]` to opt out of
gh-aw auto-injected fork activation guard. Scoped `Checkout-GhAwPr.ps1`
step to `workflow_dispatch` only (redundant for other triggers since
platform handles checkout).

2. **copilot-evaluate-tests.lock.yml**: Recompiled via `gh aw compile` —
fork guard removed from activation `if:` conditions.

3. **Checkout-GhAwPr.ps1**: Removed the `isCrossRepository` fork guard.
Updated header docs and restore comments to accurately describe behavior
for all trigger×fork combinations (including corrected step ordering).

4. **gh-aw-workflows.instructions.md**: Updated all stale references to
the removed fork guard. Documented `forks: ["*"]` opt-in, clarified
residual risk model for fork PRs, and updated troubleshooting table.

## Security Model

Fork PRs are safe because:
- Agent runs in **sandboxed container** with all credentials scrubbed
- Output limited to **1 comment** via `safe-outputs: add-comment: max:
1`
- Agent **prompt comes from base branch** (`runtime-import`) — forks
cannot alter instructions
- Pre-flight check catches missing `SKILL.md` if fork isn't rebased on
`main`
- No workspace code is executed with `GITHUB_TOKEN` (checkout without
execution)

## Testing

- ✅ `workflow_dispatch` tested against fork PR dotnet#34621
- ✅ Lock.yml statically verified — fork guard removed from `if:`
conditions
- ⏳ `pull_request` trigger on fork PRs can only be verified post-merge
(GitHub Actions reads lock.yml from default branch)

…taType is compiled (dotnet#34717)

## Description

Adds regression tests for dotnet#34713 verifying the XAML source generator
correctly handles bindings with `Converter={StaticResource ...}` inside
`x:DataType` scopes.

Closes dotnet#34713

## Investigation

After thorough investigation of the source generator pipeline
(`KnownMarkups.cs`, `CompiledBindingMarkup.cs`, `NodeSGExtensions.cs`):

### When converter IS in page resources (compile-time resolution ✅)

`GetResourceNode()` walks the XAML tree, finds the converter resource,
and `ProvideValueForStaticResourceExtension` returns the variable
directly — **no runtime `ProvideValue` call**. The converter is
referenced at compile time.

### When converter is NOT in page resources (runtime resolution ✅)

`GetResourceNode()` returns null → falls through to `IsValueProvider` →
generates `StaticResourceExtension.ProvideValue(serviceProvider)`. The
`SimpleValueTargetProvider` provides the full parent chain, and
`TryGetApplicationLevelResource` checks `Application.Current.Resources`.
The binding IS still compiled into a `TypedBinding` — only the converter
resolution is deferred.

### Verified on both `main` and `net11.0`

All tests pass on both branches.

## Tests added

| Test | What it verifies |
|------|-----------------|
| `SourceGenResolvesConverterAtCompileTime_ImplicitResources` |
Converter in implicit `<Resources>` → compile-time resolution, no
`ProvideValue` |
| `SourceGenResolvesConverterAtCompileTime_ExplicitResourceDictionary` |
Converter in explicit `<ResourceDictionary>` → compile-time resolution,
no `ProvideValue` |
| `SourceGenCompilesBindingWithConverterToTypedBinding` | Converter NOT
in page resources → still compiled to `TypedBinding`, no raw `Binding`
fallback |
| `BindingWithConverterFromAppResourcesWorksCorrectly` × 3 | Runtime
behavior correct for all inflators (Runtime, XamlC, SourceGen) |

Thank you!

## Description

Adds arcade inter-branch merge workflow and configuration to automate
merging `net11.0` into the `release/11.0.1xx-preview3` branch.

### Files added

| File | Purpose |
|------|---------|
| `github-merge-flow-release-11.jsonc` | Merge flow config — source
`net11.0`, target `release/11.0.1xx-preview3` |
| `.github/workflows/merge-net11-to-release.yml` | GitHub Actions
workflow — triggers on push to net11.0, daily cron, manual dispatch |

### How it works

Uses the shared [dotnet/arcade inter-branch merge
infrastructure](https://github.com/dotnet/arcade/blob/main/.github/workflows/inter-branch-merge-base.yml):
- **Event-driven**: triggers on push to `net11.0`, with daily cron
safety net
- **ResetToTargetPaths**: auto-resets `global.json`, `NuGet.config`,
`eng/Version.Details.xml`, `eng/Versions.props`, `eng/common/*` to
target branch versions
- **QuietComments**: reduces GitHub notification noise
- Skips PRs when only Maestro bot commits exist

### Incrementing for future releases

When cutting a new release (e.g., preview4), update:
1. `github-merge-flow-release-11.jsonc` → change `MergeToBranch` value
2. `.github/workflows/merge-net11-to-release.yml` → update workflow
`name` field

Follows the same pattern as `merge-main-to-net11.yml` /
`github-merge-flow-net11.jsonc`.

Pull request overview

Updates the .NET MAUI maui-mobile template to avoid a NullReferenceException when a selection-based navigation command is invoked with a null parameter (e.g., after returning from a minimized state on Android).

Changes:

  • Adjusts MainPageModel.NavigateToProject to return Task.CompletedTask instead of null when the selected Project is null.
Comments suppressed due to low confidence (1)

src/Templates/src/templates/maui-mobile/PageModels/MainPageModel.cs:163

  • NavigateToProject now always returns a non-null Task, but the method still declares Task? and takes a non-nullable Project even though SelectedProject is Project? (and is passed as the SelectionChangedCommandParameter from XAML). Consider updating the signature to Task NavigateToProject(Project? project) for consistent nullability.

Also, NavigateToTask(ProjectTask task) is invoked with SelectedTask (which is ProjectTask?), so it can be called with null and will throw when evaluating task.ID. It should handle a null parameter similarly (e.g., accept ProjectTask? and return Task.CompletedTask when null) to avoid another resume/deselection NRE.

		=> project is null ? Task.CompletedTask : Shell.Current.GoToAsync($"project?id={project.ID}");

	[RelayCommand]
	private Task NavigateToTask(ProjectTask task)
		=> Shell.Current.GoToAsync($"task?id={task.ID}");

Issue: #34720 - NullReferenceException in app with TabBar after returning from minimized state
PR: #34779 - [Android] Fixed NullReferenceException in app with TabBar after returning from minimized state
Platforms Affected: Android (verified on Android 9 and Android 15)
Files Changed: 1 implementation (template), 0 tests
Milestone: .NET 10 SR7

Key Findings

  • The bug is in the MAUI project template (maui-mobile), not the core framework — only affects newly created projects using this template
  • When the app resumes from a minimized state, CollectionView re-evaluates its bindings, causing SelectionChangedCommand to fire with a null SelectedProject
  • NavigateToProject(null) returns null (not a valid Task), which causes AsyncRelayCommand (CommunityToolkit.Mvvm) to crash in AwaitAndThrowIfFailed with a NullReferenceException
  • Reviewer dartasen left an inline suggestion to also remove the ? nullable annotation from the return type (Task?Task) — the PR has not yet incorporated this suggestion
  • No tests added (Gate: ⚠️ SKIPPED — no tests detected)
  • NavigateToTask (similar method below) already has Task (non-nullable) return type, so this PR makes NavigateToProject consistent with that pattern
  • Validated by Syncfusion team member (issue has partner/syncfusion label + s/verified)

Summary

The PR correctly identifies the bug and the fix direction is right — returning a non-null Task from NavigateToProject prevents the NullReferenceException in AsyncRelayCommand. However, the PR has one unresolved issue: an inline reviewer suggestion (dartasen) to change the return type from Task? to Task that must be addressed before merge.

Try-Fix exploration found that the simplest complete fix (Attempt 3) is essentially the PR's fix with the reviewer suggestion applied, and an alternative (Attempt 2) exists that better addresses the root cause at the MVVM layer.

Root Cause

When the Android app resumes from minimized state, CollectionView re-evaluates its bindings. SelectionChangedCommand fires with null as the parameter (de-selection), causing NavigateToProject(null) to return null. AsyncRelayCommand (CommunityToolkit.Mvvm) then crashes in AwaitAndThrowIfFailed when attempting to await the null Task.

This is a template bug (src/Templates/src/templates/maui-mobile/PageModels/MainPageModel.cs), not a MAUI framework bug — only affects newly created projects from the maui-mobile template.

Fix Quality

The PR's current fix is almost correct but incomplete:

Aspect PR Status Assessment
Prevents NullReferenceException ✅ Yes Returns Task.CompletedTask instead of null
Return type correctness ❌ Still Task? Reviewer suggested Task (non-nullable) — not applied
Nullable parameter annotation Project (non-nullable) Should be Project? to reflect null is possible
Test coverage ❌ None No test added (Gate skipped)
Scope ✅ Minimal Template-only, 1-file, 1-line change

Required change (from unresolved inline review):

// PR's current (incomplete):
private Task? NavigateToProject(Project project)
    => project is null ? Task.CompletedTask : Shell.Current.GoToAsync($"project?id={project.ID}");

// Correct fix (Attempt 3 — applies reviewer suggestion):
private Task NavigateToProject(Project? project)
    => project is null ? Task.CompletedTask : Shell.Current.GoToAsync($"project?id={project.ID}");

Alternative superior fix (Attempt 2 — CanExecute guard):

// Fixes root cause at MVVM layer — command never fires with null
private bool CanNavigateToProject(Project? project) => project is not null;

[RelayCommand(CanExecute = nameof(CanNavigateToProject))]
private Task NavigateToProject(Project project)
    => Shell.Current.GoToAsync($"project?id={project.ID}");

The CanExecute approach is architecturally better (prevents null from ever reaching the method), but is more code. The minimal fix (Attempt 3) is the recommended path for this PR.

Action Items for Author

  1. Must: Apply the inline reviewer suggestion — change return type from Task? to Task (reviewer: dartasen)
  2. Should: Mark the project parameter as Project? to communicate that null is a valid input
  3. Consider: The CanExecute guard pattern (Attempt 2) as a more robust alternative that prevents null execution at the command level
  4. Should: Add tests — the Gate was skipped because no tests were added. The write-tests-agent can generate appropriate tests for this regression.

Selected Fix: Attempt 3 (PR's approach + reviewer suggestion)

<!--
!!!!!!! MAIN IS THE ONLY ACTIVE BRANCH. MAKE SURE THIS PR IS TARGETING
MAIN. !!!!!!!
-->

### Root cause
When the app resumes from a minimized state, the `CollectionView` on
MainPage re-evaluates its bindings. The `SelectionChangedCommand` fires
with a `null` `SelectedProject`, calling NavigateToProject(null), which
returns `null`. The `AsyncRelayCommand` generated by RelayCommand tries
to await/check this null Task internally in `AwaitAndThrowIfFailed`,
causing the `NullReferenceException`.

### Description of Change

<!-- Enter description of the fix in this section -->
This pull request makes a minor improvement to the `NavigateToProject`
command in the `MainPageModel` to ensure it always returns a `Task`,
even when the input is null. This helps maintain consistency and
prevents potential issues with null returns.

### Issues Fixed

<!-- Please make sure that there is a bug logged for the issue being
fixed. The bug should describe the problem and how to reproduce it. -->

Fixes #34720
