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>
  
  
  <MeziantouPolyfill_IncludedPolyfills>T:Type1|T:Type2|M:Member1</MeziantouPolyfill_IncludedPolyfills>
  <MeziantouPolyfill_ExcludedPolyfills>M:System.Diagnostics.</MeziantouPolyfill_ExcludedPolyfills>

  
  <EmitCompilerGeneratedFiles>True</EmitCompilerGeneratedFiles>
  <CompilerGeneratedFilesOutputPath>$(BaseIntermediateOutputPath)\GeneratedFiles</CompilerGeneratedFilesOutputPath>
</PropertyGroup>

How to add a new polyfill

Create a new file named <xml documentation id>.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 <xml documentation id> in the file
