Update dependencies for .NET 8 and analyzers group by GabrielMarquezMatte · Pull Request #38 · GabrielMarquezMatte/FixedWidthParser

GabrielMarquezMatte · 2026-07-15T20:14:21Z

This pull request introduces .NET 8.0 multi-targeting, updates analyzer and dependency versions, and adds preliminary support for ref struct models in .NET 9.0 and above. The changes are divided into three main themes: platform support, analyzer/dependency updates, and code changes for ref struct support.

Platform and Targeting Enhancements:

Updated project files (.csproj) to multi-target both .NET 8.0 and .NET 10.0 for the main library and test projects, improving compatibility and test coverage. [1] [2]
Added System.IO.Pipelines dependency for the .NET 8.0 target to ensure feature parity.
Changed generator project to target netstandard2.1 (was netstandard2.0), and updated Microsoft.CodeAnalysis.CSharp to 5.6.0. [1] [2]

Analyzer and Dependency Updates:

Updated several analyzer package versions in Directory.Build.props to latest stable releases, including SonarAnalyzer.CSharp, Meziantou.Analyzer, Microsoft.CodeAnalysis.BannedApiAnalyzers, Roslyn.Diagnostics.Analyzers, Microsoft.CodeAnalysis.Analyzers, and SharpSource. [1] [2]
Updated test dependencies: Microsoft.CodeAnalysis.CSharp to 5.6.0 and Microsoft.Testing.Extensions.CodeCoverage to 18.9.0.

Ref struct Model Support (for .NET 9.0+):

Added conditional where TModel : allows ref struct constraints and preprocessor directives throughout the codebase to allow ref struct models when targeting .NET 9.0 or greater. This affects delegates, interfaces, parser classes, and factory methods. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [13] [14] [15] [16] [17] [18] [19]
Added a new test (guarded by #if NET9_0_OR_GREATER) to verify parsing of ref struct models. [1] [2]

These changes modernize the codebase, improve analyzer coverage, and prepare the library for advanced .NET features, especially around ref struct support in .NET 9.0 and above.
