@evgenyfedorov2 We probably should drop reading requests in Linux due to change in formula for weights from #7239.
Here's proposal.

internal sealed class KubernetesResourceQuotaProvider : ResourceQuotaProvider
{
 public override ResourceQuota GetResourceQuota()
 {
     ResourceQuota quota = new()
     {
         BaselineCpuInCores = ConvertMillicoreToCpuUnit(_kubernetesMetadata.RequestsCpu),
         MaxCpuInCores = ConvertMillicoreToCpuUnit(_kubernetesMetadata.LimitsCpu),
         BaselineMemoryInBytes = _kubernetesMetadata.RequestsMemory,
         MaxMemoryInBytes = _kubernetesMetadata.LimitsMemory,
     };

     // On Linux, CPU requests are determined with weights, where eg. 1 CPUs' weight is equal to 1.02539062
     // If we decide to read from K8s metadata it will have different results.
     if (OperatingSystem.IsLinux())
     {
         if (_useLinuxCalculationV2)
         {
             quota.BaselineCpuInCores = _parser.GetCgroupRequestCpuV2();
         }
         else
         {
             quota.BaselineCpuInCores = _parser.GetCgroupRequestCpu();
         }
     }

     if (quota.BaselineCpuInCores <= 0.0)
     {
         quota.BaselineCpuInCores = quota.MaxCpuInCores;
     }

     if (quota.BaselineMemoryInBytes == 0)
     {
         quota.BaselineMemoryInBytes = quota.MaxMemoryInBytes;
     }

     return quota;
 }
}

Pull request overview

This PR transitions the Microsoft.Extensions.Diagnostics.ResourceMonitoring.Kubernetes library from experimental/dev stage to stable by removing experimental attributes and increasing quality thresholds. However, there is a critical issue with an invalid Stage value that must be corrected.

Changes:

• Removes experimental attribute injection and dev stage diagnostic ID (EXTEXP0016)
• Changes Stage from "dev" to "stable" (invalid - should be "normal")
• Increases MinMutationScore requirement from 90 to 95

do we really need this file? I don't remember having to generate it here https://github.com/dotnet/extensions/pull/7161/changes, for instance

[amadeuszl]

I'm getting failures in the build because of lack of the experimental flag for new API. I though it will disable it but it didn't, the <EnablePackageValidation>false</EnablePackageValidation> is not fixing that either.

can you try a json file similar to this https://github.com/evgenyfedorov2/dotnet-extensions/blob/91cce8dd711dcad476be62009b146c60415d722c/src/Libraries/Microsoft.Extensions.AmbientMetadata.Build/Microsoft.Extensions.AmbientMetadata.Build.json - you can generate it with https://github.com/evgenyfedorov2/dotnet-extensions/tree/main/eng/Tools/ApiChief
