Meziantou.Polyfill

Source Generator that adds polyfill methods and types. This helps working with multi-targeted projects.

Read more about the project: Polyfills in .NET to ease multi-targeting

Installation

dotnet add package Meziantou.Polyfill

Then, you should see the generated types in the solution explorer

Generated files in the Visual Studio's Solution Explorer

Customization

By default, all needed polyfills are generated. You can configure which polyfills should be generated by editing the .csproj file and adding the following properties:

<PropertyGroup>
  <!-- semicolon-separated or pipe-separated list of name prefix -->
  <!-- Tip: The name of the generated polyfills are available in the generated "Debug.g.cs" file -->
  <MeziantouPolyfill_IncludedPolyfills>T:Type1|T:Type2|M:Member1</MeziantouPolyfill_IncludedPolyfills>
  <MeziantouPolyfill_ExcludedPolyfills>M:System.Diagnostics.</MeziantouPolyfill_ExcludedPolyfills>

  <!-- Optional: Output the generated files to the obj\GeneratedFiles folder  -->
  <EmitCompilerGeneratedFiles>True</EmitCompilerGeneratedFiles>
  <CompilerGeneratedFilesOutputPath>$(BaseIntermediateOutputPath)\GeneratedFiles</CompilerGeneratedFilesOutputPath>
</PropertyGroup>

How to add a new polyfill

Create a new file named .cs in the project Meziantou.Polyfill.Editor
Run Meziantou.Polyfill.Generator

Notes:

All files must be self contained. Use a file class if needed.
If you need to generate a file only when another polyfill is generated, add // when in the file
If xml documentation id is too long, you can use // XML-DOC: in the file
If you are not sure about the xml documentation id, you can run the generator dotnet run --project Meziantou.Polyfill.Generator -- --generate-all-symbols and open the file Meziantou.Polyfill.Editor\_AllSymbols.txt
