Description

Fixes #33420

This PR fixes a that occurs when using with nullable types during Shell navigation.

Root Cause

In ShellContent.ApplyQueryAttributes, the code used Convert.ChangeType(value, prop.PropertyType) which fails when the property type is nullable (e.g., long?, int?) because Convert.ChangeType does not handle Nullable<T> types directly.

When a user navigates with a nullable parameter like:

Dictionary<string, object> param = new() {
    { nameof(DetailsPage.ID), (long?)1 }
};
await Shell.Current.GoToAsync(nameof(DetailsPage), param);

And the destination page has:

[QueryProperty(nameof(ID), nameof(ID))]
public partial class DetailsPage : ContentPage
{
    public long? ID { get; set; }
}

The app would crash with InvalidCastException.

Solution

Use Nullable.GetUnderlyingType() to extract the underlying type before conversion:

  1. Check if the property type is nullable using Nullable.GetUnderlyingType()
  2. If nullable, extract the underlying type (e.g., long from long?)
  3. Convert the value to the underlying type
  4. Assign (automatic wrapping in nullable occurs)
  5. Handle null values explicitly

Changes

Fix:

  • src/Controls/src/Core/Shell/ShellContent.cs - Added nullable type handling in ApplyQueryAttributes

Tests:

  • Added UI test Issue33420 that reproduces the issue and verifies the fix
  • Test navigates with a nullable long? parameter and verifies navigation succeeds

Testing

✅ Tests fail without the fix (reproduces the crash)
✅ Tests pass with the fix (navigation works)
✅ Verified on iOS simulator

Platforms Affected

All platforms (iOS, Android, Windows, MacCatalyst) - Shell navigation code is shared.

📋 Issue Summary

Description:
Unable to pass nullable values via QueryPropertyAttribute during Shell navigation. When navigating with a nullable parameter, the app crashes with System.InvalidCastException.

Root Exception:

System.Private.CoreLib.dll!System.Convert.DefaultToType(System.IConvertible value, System.Type targetType, System.IFormatProvider provider)
Microsoft.Maui.Controls.dll!Microsoft.Maui.Controls.ShellContent.ApplyQueryAttributes(object content, Microsoft.Maui.Controls.ShellRouteParameters query, Microsoft.Maui.Controls.ShellRouteParameters oldQuery)

Thank you!

## Description

Cherry-pick of
[`5d6e5a20`](dotnet@5d6e5a2)
from `net11.0`, adapted for `main`.

Fixes dotnet#34428

### Problem

Release 10.0.50 introduced a performance optimization (`_isSubscribed`
flag) in `TypedBinding` that prevented re-subscribing to intermediate
INPC objects when they changed. This caused compiled bindings with
nested property paths (e.g. `{Binding ViewModel.Text}`) to stop updating
when the intermediate object was replaced.

### Fix

Remove the `_isSubscribed` guard and always call `Subscribe()` on every
`Apply`. The `Subscribe()` implementation is already idempotent — it
diffs old vs new subscription targets — so calling it repeatedly is safe
with minimal overhead.

### Tests

Two regression tests added to `TypedBindingUnitTests.cs`:
-
`TypedBinding_NestedProperty_ResubscribesAfterNullIntermediateBecomesNonNull`
- `TypedBinding_NestedProperty_ResubscribesAfterIntermediateReplaced`

Issue: #33420 - System.InvalidCastException when using QueryPropertyAttribute with nullable types
PR: #33429 - [PR-Agent] Fix #33420: Handle nullable types in QueryPropertyAttribute
Platforms Affected: All (iOS, Android, Windows, MacCatalyst) — Shell navigation code is shared
Files Changed: 1 implementation, 3 test

Key Findings

  • ShellContent.ApplyQueryAttributes used Convert.ChangeType(value, prop.PropertyType) which fails for nullable types (long?, int?, etc.) because Convert.ChangeType does not support Nullable<T> targets directly
  • Root exception: System.InvalidCastException thrown from Convert.DefaultToType when target is a nullable type
  • Fix uses Nullable.GetUnderlyingType(prop.PropertyType) to extract the underlying type (e.g., long from long?), then converts to that, relying on implicit boxing to wrap back into nullable
  • Fix also handles null value explicitly by calling prop.SetValue(content, null) directly
  • Issue verified by Microsoft on Android, Windows, iOS, MacCatalyst (versions 9.0.0 through 10.0.20)
  • PR has community ✨ and s/agent-reviewed, s/agent-approved labels already
  • Prior agent review from PR author (kubaflo) recommends APPROVE
  • Inline Copilot review comment flags .github/agent-pr-session/pr-33420.md file — but this file is NOT in current changed files (likely stale from earlier commit)
  • Test uses XAML-based Shell with QueryProperty navigating from MainPageIssue33420DetailsPage with long? ID parameter

Summary

PR #33429 fixes a System.InvalidCastException that occurs when navigating via Shell.GoToAsync with nullable value types (e.g., long?, int?) as QueryProperty parameters. The fix is minimal (12 additions, 2 deletions), correct, and well-tested with a UI test that reproduces the crash. Gate verification confirms tests fail without the fix and pass with it. Two independent alternative fixes were explored and both also passed, but both are more complex than the PR's approach. The PR's fix is the simplest and most idiomatic solution.

Root Cause

ShellContent.ApplyQueryAttributes called Convert.ChangeType(value, prop.PropertyType) where prop.PropertyType is a Nullable<T> (e.g., long?). The BCL's Convert.ChangeType does not support Nullable<T> as the target type and throws InvalidCastException. This affects all platforms since ShellContent is shared code.

Fix Quality

Correctness: ✅ The fix correctly uses Nullable.GetUnderlyingType(prop.PropertyType) ?? prop.PropertyType to extract the underlying type before calling Convert.ChangeType. Since the underlying type (e.g., long) is supported by Convert.ChangeType, the conversion succeeds and reflection's prop.SetValue automatically boxes the result into the nullable wrapper.

Null handling: ✅ Added explicit null guard that sets the property to null directly, avoiding a NullReferenceException in Convert.ChangeType.

Minimality: ✅ Only 12 lines added, 2 removed — surgical change to exactly the failing code path.

Test coverage: ✅ UI test reproduces the exact crash scenario (long? ID via QueryProperty, Shell navigation). Test verifies both that navigation succeeds and that the value ("Success: ID=1") was correctly received.

Selected Fix: PR's fix — confirmed best among 3 candidates (PR + 2 independent alternatives).

Concerns / Minor Notes

  • The test file uses XAML (.xaml + .xaml.cs) rather than C#-only, which is acceptable since the test involves a Shell with ShellContent (a XAML-appropriate pattern).
  • Issue33420DetailsPage uses a BindableProperty for ID (long?) rather than a plain auto-property. This is slightly more complex than needed for the test but is valid and tests the most realistic use case.
  • No concerns about the fix itself — Nullable.GetUnderlyingType is the canonical API for this pattern in .NET.

### Issues Fixed

Fixes #33420

Phase 2: Code Review

✅ Core Fix — ShellContent.cs

File: src/Controls/src/Core/Shell/ShellContent.cs (lines 419–430)

The fix is minimal, targeted, and correct:

// Handle nullable types
Type targetType = Nullable.GetUnderlyingType(prop.PropertyType) ?? prop.PropertyType;

if (value == null)
{
    prop.SetValue(content, null);
}
else
{
    var castValue = Convert.ChangeType(value, targetType);
    prop.SetValue(content, castValue);
}
  • Nullable.GetUnderlyingType() correctly extracts long from long?, falling back to the original type for non-nullable properties — standard .NET pattern
  • Null handling is explicitly separated, which is correct: Convert.ChangeType(null, typeof(long)) would throw, so the null guard is needed
  • No behavioral regression for existing non-nullable paths (the ?? prop.PropertyType fallback preserves the original behavior)

🟡 Minor Issues

1. Trailing whitespace in ShellContent.cs (cosmetic)

The diff shows a blank line with trailing whitespace after the Type targetType declaration:

+								Type targetType = Nullable.GetUnderlyingType(prop.PropertyType) ?? prop.PropertyType;
+								
+								if (value == null)

The middle line contains tabs. Minor formatting issue — dotnet format would clean this up.

2. Test uses XAML for Shell definition (acceptable)

Issue33420.xaml defines a Shell in XAML, which is appropriate here since Shell structure is inherently XAML-oriented (routes, NavBar visibility). The inner page content pages (Issue33420MainPage, Issue33420DetailsPage) are correctly written in C#. Pattern is consistent with similar Shell issue tests.

3. Issue33420DetailsPage uses BindableProperty instead of a plain auto-property (over-engineered for a test)

The details page uses:

public long? ID
{
    get => (long?)GetValue(IDProperty);
    set => SetValue(IDProperty, value);
}
public static readonly BindableProperty IDProperty = 
    BindableProperty.Create(nameof(ID), typeof(long?), ..., propertyChanged: OnIDChanged);

A simpler auto-property with a setter that updates the label would suffice for this test. However, this approach works correctly and doesn't affect test correctness — it's just more complex than necessary.

4. Test assertion could be more robust

var resultText = App.FindElement("ResultLabel").GetText();
Assert.That(resultText, Is.EqualTo("Success: ID=1"));

The button changes text to "Error: ..." on exception (in Issue33420MainPage), but that button is on the first page and the test navigates away from it. The App.WaitForElement("ResultLabel") will timeout if navigation fails (which will fail the test), so the overall test logic is sound. The assertion on the exact label text is a good positive verification.


✅ Looks Good

  • Fix is correct for all platforms (Shell navigation code is shared — no platform-specific handling needed)
  • [Category(UITestCategories.Shell)] is the right category for this test
  • Test correctly uses AutomationId on all interactive elements
  • HostApp page correctly inherits Shell (not ContentPage) for the root, matching the issue scenario
  • Routing.RegisterRoute is properly called in the Shell constructor

## Description

Fixes #33420

This PR fixes a that occurs when using with nullable types during Shell
navigation.

## Root Cause

In `ShellContent.ApplyQueryAttributes`, the code used
`Convert.ChangeType(value, prop.PropertyType)` which fails when the
property type is nullable (e.g., `long?`, `int?`) because
`Convert.ChangeType` does not handle `Nullable<T>` types directly.

When a user navigates with a nullable parameter like:
```csharp
Dictionary<string, object> param = new() {
    { nameof(DetailsPage.ID), (long?)1 }
};
await Shell.Current.GoToAsync(nameof(DetailsPage), param);
```

And the destination page has:
```csharp
[QueryProperty(nameof(ID), nameof(ID))]
public partial class DetailsPage : ContentPage
{
    public long? ID { get; set; }
}
```

The app would crash with `InvalidCastException`.

## Solution

Use `Nullable.GetUnderlyingType()` to extract the underlying type before
conversion:

1. Check if the property type is nullable using
`Nullable.GetUnderlyingType()`
2. If nullable, extract the underlying type (e.g., `long` from `long?`)
3. Convert the value to the underlying type
4. Assign (automatic wrapping in nullable occurs)
5. Handle null values explicitly

## Changes

**Fix:**
- `src/Controls/src/Core/Shell/ShellContent.cs` - Added nullable type
handling in `ApplyQueryAttributes`

**Tests:**
- Added UI test `Issue33420` that reproduces the issue and verifies the
fix
- Test navigates with a nullable `long?` parameter and verifies
navigation succeeds

## Testing

✅ Tests fail without the fix (reproduces the crash)
✅ Tests pass with the fix (navigation works)
✅ Verified on iOS simulator

## Platforms Affected

All platforms (iOS, Android, Windows, MacCatalyst) - Shell navigation
code is shared.
