Updated the TargetFrameworks in both CommunityToolkit.Mvvm.Roslyn5000.UnitTests and CommunityToolkit.Mvvm.SourceGenerators.Roslyn5000.UnitTests projects to include net10.0 for future .NET compatibility testing.
Changed the LangVersion property from 'preview' to '14.0' in the CommunityToolkit.Mvvm.Roslyn5000.UnitTests.csproj file to explicitly target C# 14.0 for test builds.
Eliminated the temporary workaround for Roslyn 5.0.0 in the props file and updated the test project's Microsoft.CodeAnalysis.CSharp.Workspaces package reference from 5.0.0-2.final to 5.0.0. This aligns the configuration with the stable Roslyn release.
Introduces new unit tests for ObservableProperty with value types on partial properties using C# 14 and Roslyn 5.0.0 or greater. Also updates formatting in diagnostics tests for consistency and readability.
Added CommunityToolkit.Mvvm.SourceGenerators.Roslyn5000.UnitTests project to the solution and corrected the project reference in CommunityToolkit.Mvvm.csproj to point to the correct Roslyn5000 source generator. This enables testing for Roslyn 5.0.0 support.
Introduces CommunityToolkit.Mvvm.Roslyn5000.UnitTests.csproj targeting net472, net8.0, and net9.0. Updates the solution file to include the new test project for Roslyn 5.0.0 compatibility testing.
Renamed RequiresCSharpLanguageVersionPreviewAnalyzer to RequiresCSharpLanguageVersion14OrPreviewAnalyzer and updated logic to check for C# 14.0 or preview language versions. Adjusted generator and unit tests to reference the new analyzer and updated version checks for compatibility with Roslyn 5.0.0 or greater.
Revised the XML summary comment to clarify that the extension methods are for working with diagnostics from incremental generator pipelines, rather than specifically for GeneratorExecutionContext.
Refactored the Roslyn 5000 project to import shared props and projitems files. Added support for the ROSLYN_5_0_0_OR_GREATER constant, updated NoWarn conditions for RS2003, and introduced a temporary workaround for Roslyn 5.0.0 versioning in the props file.
Updated the ObservableProperty generator and diagnostics to allow usage with C# 14.0 or 'preview' language versions, not just 'preview'. Added a new helper method for language version comparison and updated diagnostic descriptors and analyzer logic to reflect the new minimum version requirement.
Bump .NET SDK version to 10.0.100 in global.json and update NuGet operations to use 10.0.x in CI workflow. Simplify MVVM Toolkit error message to recommend using the latest .NET SDK version.
Moved the ParallelizeAttribute configuration from individual test project files to the shared Community.Toolkit.Common.targets file. This centralizes the configuration and ensures all test projects run tests in parallel by default.
Added the Microsoft.VisualStudio.TestTools.UnitTesting.ParallelizeAttribute to all MSTest-based unit test project files to enable parallel test execution. This change should improve test run performance by allowing tests to run concurrently.
Updated assertions in Test_RelayCommandAttribute_WithPartialCommandMethodDefinitions to assign results to the discard variable, improving code clarity and suppressing possible warnings about unused return values.
Updated unit tests in Test_ObservableValidator.cs to use Assert.HasCount instead of Assert.AreEqual for collection count assertions. This improves clarity and consistency in test assertions.
Updated all usages of Assert.HasCount to explicitly cast stream.Position to int. This ensures type consistency and prevents potential issues when stream.Position is a long.
Replaces usages of Assert.AreEqual, Assert.IsTrue, and similar assertions with new helper methods such as Assert.HasCount, Assert.IsEmpty, Assert.IsNull, and Assert.IsGreaterThanOrEqualTo across multiple test files. This improves test readability and consistency with updated assertion APIs.
Updated all unit tests to consistently use the expected value as the first argument in Assert.AreEqual calls. This improves readability and aligns with best practices for test assertions.
Upgraded MSTest.TestAdapter and MSTest.TestFramework from version 3.11.0 to 4.0.1 across all unit test project files to ensure compatibility with the latest features and bug fixes.
Eliminated repeated [DataRow(64, 4, 0)] attributes from three test methods in Test_MemoryExtensions.cs to avoid redundant test cases and improve test clarity.
Replaces usage of Assert.ThrowsException with Assert.ThrowsExactly across multiple unit test files to ensure that tests only pass when the exact exception type is thrown, improving test precision and reliability.
Upgrades MSTest.TestAdapter and MSTest.TestFramework from 3.6.4 to 3.11.0 across all unit test project files to ensure compatibility with latest features and bug fixes.
Replaces all conditional compilation checks for NET7_0_OR_GREATER with NET8_0_OR_GREATER and removes .NET 7.0 from the target frameworks in the project file. This ensures the codebase is aligned with .NET 8.0 features and APIs, simplifying maintenance and leveraging the latest platform improvements.
