AOT remove assemblies not used.

[AlbertoMonteiro]

Hi!!

First I would like to thank you guys for providing such amazing framework!!

I am trying to help the owner of regex101 site adding C# regex support.
Thats the issue firasdib/Regex101#156.

I created that repo to provide an way to run regex C# engine from js.
https://github.com/AlbertoMonteiro/RegexWasmUno

I am using FullAOT version, but when I was checking network calls, I saw many assemblies being fetched that I don't use, like System.Net.Mail.

Is there an way to remove those unwanted/unused assemblies?

Also there is any tip to improve performance even further?

Thanks for the report! This is actually caused by #423, where the package is forcibly added to all projects referencing Uno.Wasm.Bootstrap.

You may try a work around by adding this to your project:

  <Target Name="RemoveBootstrapCompatibilityRef" AfterTargets="WasmBootstrapAdjustFrameworkReference">
    <ItemGroup>
      <PackageReference Remove="Microsoft.Windows.Compatibility" />
    </ItemGroup>
  </Target>

@jeromelaban I've added many assemblies, including the one that you mentioned but it didn't worked, the publish output still generate those files.
I've tried adding only that code that you mentioned, but the result was the same.
