What is it? 🚀

PolySharp provides Source-only polyfills for C# language features, to easily use all runtime-agnostic features downlevel. The package is distributed as a source generator, so that it will automatically detect which polyfills are needed depending on the target framework and project in use: just add a reference to PolySharp, set your C# language version to latest, and have fun!

Documentation 📖

PolySharp includes the following polyfills:

  • Nullability attributes (for nullable reference types):
    • [AllowNull]
    • [DisallowNull]
    • [DoesNotReturn]
    • [DoesNotReturnIf]
    • [MaybeNull]
    • [MaybeNullWhen]
    • [MemberNotNull]
    • [MemberNotNullWhen]
    • [NotNull]
    • [NotNullIfNotNull]
    • [NotNullWhen]
  • Index and Range (see indices and ranges)
  • [UnscopedRef] (see low-level struct improvements)
  • Required members (see required modifier)
    • [RequiredMember]
    • [SetsRequiredMembers]
  • [CompilerFeatureRequired] (needed to support several features)
  • [IsExternalInit] (needed for init-only properties)
  • [SkipLocalsInit] (see docs)
  • Interpolated string handlers (see docs)
    • [InterpolatedStringHandler]
    • [InterpolatedStringHandlerArgument]
  • [CallerArgumentExpression] (see docs)

To leverage them, make sure to bump your C# language version. You can do this by setting the <LangVersion> MSBuild property in your project. For instance, by adding <LangVersion>11.0</LangVersion> (or your desired C# version) to the first <PropertyGroup> of your .csproj file. For more info on this, see here, but remember that you don't need to manually copy polyfills anymore: simply adding a reference to PolySharp will do this for you automatically.

Options ⚙️

PolySharp's generation can be configured through some MSBuild properties to set in consuming projects.

The following properties are available:

  • "PolySharpUsePublicAccessibilityForGeneratedTypes": changes the accessibility of generated types from internal to public.
