Net4x.BaseExtensions

Net4x.BaseExtensions is a small compatibility and helper library that complements Net4x.BaseTypes. It provides extension methods, light-weight memory/span helpers, and small utilities that make it easier to write code that runs across many .NET target frameworks (from older .NET Framework versions up to modern .NET).

The library focuses on portability and low-dependency abstractions so it can be included in projects that must support a wide range of TFMs.

Key features

  • Extension methods for common types to reduce boilerplate
  • Lightweight ReadOnlySpan/Memory shims and helpers for older TFMs
  • Simplified event handling helpers and EventHandler compatibility code
  • Encoding detection and string-related helpers
  • Utilities intended for use inside shared libraries and multi-targeted projects

Supported target frameworks

This project is multi-targeted to improve compatibility. Typical TFMs included are:

  • .NET Standard 2.0 and 2.1
  • .NET Framework 2.0, 3.0, 3.5, 4.0, 4.5, 4.6.2, 4.7.2
  • .NET 6, .NET 8, .NET 10

Project layout

  • src/Net4x.BaseExtensions - Core extension methods and compatibility code (multi-targeted)
    • EventHandler.cs - helpers to unify event patterns
    • ReadOnlySpan.cs, Memory.cs - compatibility types and helpers
    • other helpers and extension files
  • tests/Net4x.BaseTypes.Tests - unit tests that exercise Net4x.BaseExtensions and Net4x.BaseTypes

Building

Build the project or solution using the .NET SDK installed on your machine. Example commands:

  • Build everything:

    dotnet build

  • Build only this project:

    dotnet build src/Net4x.BaseExtensions/Net4x.BaseExtensions.csproj

Running tests

Unit tests that exercise this library are included in the tests folder. Run them with:

dotnet test

Usage

Add a project reference to Net4x.BaseExtensions or add the compiled assembly to your project. Because the library is multi-targeted, you can reference the appropriate build for your target framework.

Contributing

Contributions are welcome. When opening pull requests:

  • Keep changes focused and small
  • Add or update unit tests for new behavior or bug fixes
  • Maintain compatibility with supported TFMs unless intentionally changing targets
