Subject: [PATCH 05/36] Updating tests to use TUnit and MTP (#3838)

* Updating to xUnit v3 1.x

* Adding MTP

https://devblogs.microsoft.com/dotnet/mtp-adoption-frameworks/

* Starting conversion to TUnit

* Tests all compile

* Adds cancellation tokens to async delays

Ensures that asynchronous delay calls use cancellation tokens to allow for tests to be cancelled correctly.

* WIP

* Refactors test suite and updates dependencies

Updates the test suite to use TUnit for improved test clarity and maintainability.
Removes unused xunit packages and addresses nullable warnings in RatingBar converters.
Also includes changes to CustomColorTheme, DataGridAssist, DialogHost, DrawerHost, FlipperAssist, Internal/TreeListViewItemsCollection, Label, MaterialDesignThemes.Wpf.Tests.csproj, MdixHelper, PackIcon, PopupBox, RatingBar, SnackbarMessageQueue, TextBlock, TextBox, Theme and Transitioner tests.

* Updates test framework and fixes assertions

Updates test framework from Fact to Test.

Updates tests to use Assert.That for improved readability and consistency.

* Reverting stupid

* Save point

* Assert.True

* Updates tests to be async

Updates tests to be async to prevent possible deadlocks and improve reliability.

* Removes TUnit dependencies from tests

Removes the TUnit library and associated code from test projects, modernizing testing using the default testing framework.

* Tests are now compiling

* Updates test framework for DecimalUpDown

Converts the DecimalUpDown test to use the `Arguments` attribute and updates assertions to improve reliability and clarity.

* Fixing member data sources

Updates TimePicker unit tests to use MethodDataSource with Func to prevent test data from being eagerly evaluated, resolving issues with the test framework.

* Refactors code for brevity and adds tests

Updates collection initialization to use more concise syntax.
Adds tests for the ButtonProgressAssist, CheckBoxAssist, ColorPicker, and DataGridAssist classes.
Adds a new test executor and removes redundant STAThreadExecutor attributes.
Adds NotInParallel attribute to CalendarFormatInfoTests and DialogHostTests.
Refactors the PreviewIndicatorTransformXConverter and PreviewIndicatorTransformYConverter.

* Updates screenshot artifact path

Updates the path for screenshot artifacts to target the .NET 9 framework.

* Fixes artifact upload path

Corrects the artifact upload path in the build workflow.

* Updates coordinate assertion method

Uses IsCloseTo method for asserting coordinate proximity in UI tests for ComboBoxes, DatePickers, PasswordBoxes, and TextBoxes.
This improves the accuracy and reliability of the tests by checking if the coordinates are within a specified tolerance range.

* Updates NuGet package versions

Updates several NuGet package versions, including Microsoft.NET.Test.Sdk, TUnit, and XAMLTest.

Fixes a potential issue in a test case by using CancellationToken.None instead of TestContext.Current!.CancellationToken

* Fixes UI test failures

Corrects failing UI tests by adjusting assertions and adding exception handling.

The fixes improve the stability and reliability of the UI test suite.

* Fixes combo box test assertion

Updates test assertion to expect a null text value when a combo box is uninitialized.
This corrects the expected behavior of the test.

* Updates artifact path for .NET 9

Updates the artifact upload path in the build workflow to correctly target the .NET 9 framework.
This resolves an issue where artifacts were not being correctly uploaded due to an incorrect target framework name.

* Adds success recorder in auto suggest box tests

* Skips flaky GetDialogSession test

* Skips failing saturation drag test

Skips a ColorPicker test that was failing before the move to Machine.Time.Past due to timing issues in the while loop.

* Ensures DialogHost is properly unloaded

Introduces a `ControlHost` class to ensure the `DialogHost` is properly unloaded when the test is complete.
This prevents orphaned `DialogHost` instances from interfering with subsequent tests.

Subject: [PATCH 09/36] Embeds icon into NuGet packages (#3900)

Updates NuGet packages to embed an icon, instead of referencing an icon URL.

This change improves the NuGet package display and provides a more consistent user experience.
It removes the need to download the icon separately and ensures the icon is always available, even if the URL becomes invalid.

+# Copilot Instructions for MaterialDesignInXamlToolkit
+
+## Repository Overview
+
+The MaterialDesignInXamlToolkit is a **theme library** for WPF applications that provides Material Design themes and styling. This is NOT a control library - the focus is on theming existing WPF controls and providing custom controls only when necessary to support Google's Material Design specifications.
+
+### Key Principles
+- Theme library, not control library
+- Styling existing WPF controls to match Material Design
+- Custom controls only for Google-specified components that don't exist in WPF
+- No application or business logic belongs in this library
+- Provide base tools and springboard for developers to create their own controls
+
+## Architecture and Structure
+
+### Core Projects
+- **`MaterialDesignThemes.Wpf`** - Main theming library with styles, templates, and controls
+- **`MaterialDesignColors.Wpf`** - Color palette and theme management
+- **`MaterialDesignThemes.MahApps`** - Integration with MahApps.Metro
+- **`MainDemo.Wpf`** - Primary demonstration application
+- **`MaterialDesign3.Demo.Wpf`** - Material Design 3 demonstration
+- **`MaterialDesignToolkit.ResourceGeneration`** - Build-time resource generation tools
+
+### Key Technologies
+- **WPF (Windows Presentation Foundation)** - UI framework
+- **XAML** - Markup for UI definitions and styles  
+- **Material Design** - Google's design system implementation
+- **.NET 9** - Target framework
+- **C# 12.0** - Programming language
+- **PowerShell** - Build automation scripts
+
+## Development Environment
+
+### Requirements
+- **Windows** - Required for WPF development and compilation
+- **.NET 9 SDK** - As specified in `global.json`
+- **Visual Studio** or **Visual Studio Code** with C# extension
+- **PowerShell** - For build scripts
+
+### Build and Test
+```powershell
+# Restore dependencies
+dotnet restore MaterialDesignToolkit.Full.sln
+
+# Build (requires Windows)
+dotnet build MaterialDesignToolkit.Full.sln --configuration Release --no-restore -p:Platform="Any CPU" -p:TreatWarningsAsErrors=True
+
+# Run tests
+dotnet test MaterialDesignToolkit.Full.sln --configuration Release --no-build
+
+# Build NuGet packages
+.\build\BuildNugets.ps1 -MDIXVersion "x.x.x" -MDIXColorsVersion "x.x.x" -MDIXMahAppsVersion "x.x.x"
+```
+
+## Code Style and Conventions
+
+### General Guidelines
+- Follow standard Visual Studio settings with ReSharper suggestions
+- Use .editorconfig settings (4-space indents for C#, 2-space for XAML/XML)
+- Allman brace style (`csharp_new_line_before_open_brace = all`)
+- No `this.` qualification unless necessary
+- Prefer explicit types over `var` for built-in types
+- Use PascalCase for public members, interfaces start with `I`
+
+### C# Conventions
+```csharp
+// Preferred dependency property pattern
+public static readonly DependencyProperty MyPropertyProperty =
+    DependencyProperty.Register("MyProperty", typeof(string), typeof(MyControl), 
+        new UIPropertyMetadata("DefaultValue", OnMyPropertyChanged));
+
+public string MyProperty
+{
+    get => (string)GetValue(MyPropertyProperty);
+    set => SetValue(MyPropertyProperty, value);
+}
+
+private static void OnMyPropertyChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
+{
+    var control = (MyControl)d;
+    // Handle property change
+}
+```
+
+### XAML Style Guidelines
+- Use XamlStyler settings from `Settings.XamlStyler`
+- 2-space indentation for XAML
+- Keep first attribute on same line as element
+- Order attributes according to defined groups
+- Use `{StaticResource}` over `{DynamicResource}` where possible
+- Follow resource naming: `MaterialDesign.Brush.Primary.Light`
+
+## WPF and Material Design Context
+
+### Theme Architecture
+- **Base Themes**: Light and Dark variants
+- **Color System**: Primary, Secondary, Surface, Background colors with variants
+- **Elevation**: Shadow and overlay systems for depth
+- **Typography**: Material Design text styles
+- **Motion**: Transitions and animations
+
+### Common Patterns
+```csharp
+// Theme modification pattern
+private static void ModifyTheme(Action<Theme> modificationAction)
+{
+    var paletteHelper = new PaletteHelper();
+    Theme theme = paletteHelper.GetTheme();
+    
+    modificationAction?.Invoke(theme);
+    
+    paletteHelper.SetTheme(theme);
+}
+
+// Color adjustment usage
+theme.ColorAdjustment = new ColorAdjustment
+{
+    DesiredContrastRatio = desiredRatio,
+    Contrast = contrastValue,
+    Colors = colorSelection
+};
+```
+
+### Resource Dictionary Patterns
+```xml
+<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
+                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
+                    xmlns:materialDesign="http://materialdesigninxaml.net/winfx/xaml/themes">
+  
+  <ResourceDictionary.MergedDictionaries>
+    <materialDesign:BundledTheme BaseTheme="Light" PrimaryColor="DeepPurple" SecondaryColor="Lime" />
+    <ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/Generic.xaml" />
+  </ResourceDictionary.MergedDictionaries>
+
+</ResourceDictionary>
+```
+
+## Testing Approach
+
+### Test Structure
+- **Unit Tests**: `MaterialDesignThemes.Wpf.Tests`, `MaterialDesignColors.Wpf.Tests`
+- **UI Tests**: `MaterialDesignThemes.UITests` - Visual/integration testing
+- **Demo Applications**: Manual testing and showcasing functionality
+
+### Test Patterns
+```csharp
+[Test]
+public async Task ThemeTest_Example()
+{
+    await App.InitializeWithMaterialDesign(
+        baseTheme: BaseTheme.Light,
+        primary: PrimaryColor.Blue,
+        secondary: SecondaryColor.Orange);
+        
+    // Test implementation
+}
+```
+
+## Build Pipeline and Automation
+
+### GitHub Actions Workflows
+- **PR Verification**: `pr_verification.yml` - Build and test on PRs
+- **Build Artifacts**: `build_artifacts.yml` - Main build pipeline
+- **Release**: `release.yml` - Create releases and publish NuGets
+
+### PowerShell Build Scripts
+- **`BuildNugets.ps1`** - Package creation
+- **`ApplyXamlStyler.ps1`** - Code formatting
+- **`MigrateBrushes.ps1`** - Resource migration utilities
+- **`UpdateNugets.ps1`** - Package management
+
+## Domain-Specific Knowledge
+
+### Material Design Implementation
+- Follow Google Material Design guidelines strictly
+- Implement elevation through shadows and overlays
+- Use consistent color theming system
+- Support both Material Design 2 and 3 specifications
+- Ensure accessibility compliance (contrast ratios, touch targets)
+
+### WPF Theming Best Practices
+- Use `TemplateBinding` for connecting to parent properties
+- Implement proper focus visuals and keyboard navigation
+- Support high contrast mode and accessibility features
+- Use appropriate triggers for state changes (hover, pressed, disabled)
+- Leverage WPF's dependency property system effectively
+
+### Resource Organization
+- Brush resources: `MaterialDesign.Brush.*`
+- Style resources: Clear, descriptive names matching WPF conventions
+- Template resources: Match control types and variants
+- Color resources: Follow Material Design naming (Primary, Secondary, Surface, etc.)
+
+## API Design Guidelines
+
+- **Maintain backward compatibility** - This is a widely-used library
+- **Minimal public API surface** - Only expose what's necessary
+- **Consistent naming** - Follow WPF and Material Design conventions
+- **Proper documentation** - XML docs for all public APIs
+- **Designer support** - Ensure controls work well in Visual Studio designer
+
+## Common Tasks and Patterns
+
+### Adding a New Style
+1. Define in appropriate XAML resource dictionary
+2. Follow existing naming conventions
+3. Test in demo applications
+4. Ensure accessibility compliance
+5. Add to migration scripts if replacing existing styles
+
+### Theme Modifications
+1. Use `PaletteHelper` for runtime theme changes
+2. Support both static and dynamic resource binding
+3. Test with both Light and Dark themes
+4. Verify color adjustments work properly
+
+### Custom Control Development
+1. Only when no WPF equivalent exists
+2. Follow Material Design specifications exactly
+3. Implement proper template parts and visual states
+4. Support theming and color adjustments
+5. Include comprehensive tests and demo usage
+
+Remember: This library's primary goal is to provide a complete, high-quality Material Design theming solution for WPF applications while maintaining excellent performance and broad compatibility.

Subject: [PATCH 18/36] Fixes NuGet package creation output path (#3911)

Changes the NuGet package creation to output to the current directory
instead of the default location.

This resolves issues with the build script not finding the created
packages in the expected location.

Removes unused Azure pipeline YAML file.

Subject: [PATCH 27/36] Prefer TemplateBinding over Binding with RelativeSource
 (#3930)

* Prefer TemplateBinding over Binding with RelativeSource

* Updates Expander control template

Changes `ContentSite` border to be unnamed and binds `ExpandDirection` directly from the `TemplateBinding`.

Subject: [PATCH 29/36] Fix horizontal ScrollBar placement for multi-line
 TextBox (#3934)

* Add simple issue repro to Home page

* WIP on fix.

Scroll position is now synced correctly, but the visibility property still needs to be respected properly.

* TextBox.HorizontalScrollBarVisibility is now respected

* Add null guards and possibly not-needed method SizeChanged() invoke

* Remove not needed invocation and null forgiving operators

* Place custom scrollbar correctly using converters

* Cleanup

* Take hover/focus state into account + ignore margins on hidden elements

* Only consider hover/focus when style is outlined

* Removing simple repro from Home page

* Update demo app with TextBox.TextWrapping option on Field page

* Fix initial state of custom ScrollBar

* Renames property for clarity.

Renames `isOutlinedStyle` to `hasOutlinedTextField` in `TextBoxHorizontalScrollBarMarginConverter` for better clarity and consistency.

* Improves UI test reliability

Adds retry logic to clear button click in date picker test; captures a screenshot of the split button popup during UI test.

* Moved converters into "internal" namespace

* Moved behavior into new "internals" namespace for behaviors

 (#3920)

* Porting material-color-utilities to dotnet #2475

Backporting to .NET 462

* Implementing unit tests for MaterialColorUtilities

* Making enum values PascalCase and using explicit types where not obvious

* Modernizes test code syntax

Uses collection expressions and generic `Enum.GetValues`, suppresses obsolete member warnings, and removes an unnecessary assertion.
