@agocke is rewriting naot targets

[dellamonica]

I tried building with the mcr.microsoft.com/dotnet/nightly/sdk:10.0-preview-alpine-aot docker image and got NuGet errors that look similar to this.

Unable to find package runtime.linux-musl-x64.Microsoft.DotNet.ILCompiler with version (= 10.0.0-rc.1.25425.114)

Is there a workaround?

[agocke]

FYI, rewrite is too risky for .NET 10 so this will go into .NET 11.

[agocke]

Current workaround is:

  <ItemGroup>
    <PackageReference Include="Microsoft.DotNet.ILCompiler" Version="10.0.0-rtm.25507.103" />
    <KnownRuntimePack Update="@(KnownRuntimePack)">
      <LatestRuntimeFrameworkVersion Condition="'%(KnownRuntimePack.Identity)' == 'Microsoft.NETCore.App'
      and '%(KnownRuntimePack.RuntimePackLabels)' == 'NativeAOT'
      and '%(KnownRuntimePack.TargetFramework)' == 'net10.0'">10.0.0-rtm.25507.103</LatestRuntimeFrameworkVersion>
    </KnownRuntimePack>
    <KnownILCompilerPack Update="@(KnownILCompilerPack)">
      <ILCompilerPackVersion Condition="'%(KnownILCompilerPack.TargetFramework)' == 'net10.0'">10.0.0-rtm.25507.103</ILCompilerPackVersion>
    </KnownILCompilerPack>
  </ItemGroup>

where the version number in the above is replaced with the desired version.
