Performance degradation under .NET 10 SDK

[W-Sebastian]

I minimized the issue to the following minimum reproducible csproj:

dotnet-10-performance-degration.csproj:

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFramework>net8.0-windows</TargetFramework>
    <ReportAnalyzer>true</ReportAnalyzer>
  </PropertyGroup>
  
  <ItemGroup>
    <PackageReference Include="Pure.DI" Version="2.2.14">
      <PrivateAssets>all</PrivateAssets>
      <IncludeAssets>none</IncludeAssets>
    </PackageReference>

    <PackageReference Include="TestableIO.System.IO.Abstractions.Analyzers" Version="2022.0.0">
      <PrivateAssets>all</PrivateAssets>
      <IncludeAssets>none</IncludeAssets>
    </PackageReference>

    <PackageReference Include="TestableIO.System.IO.Abstractions.Wrappers" Version="22.0.16" >
      <PrivateAssets>all</PrivateAssets>
      <IncludeAssets>compile</IncludeAssets>
    </PackageReference>
  </ItemGroup>
</Project>

Run this under .NET 10.0.100 with the command:

dotnet build dotnet-10-performance-degration.csproj -bl.

Note that there is no source file here, just the csproj is sufficient.
Upon inspecting the generate binary log file we can see the following:

For whatever reason the analyzer takes about 4 seconds to run which amounts to around 30ish second per project where this combination of analyzers exists.

Removing any of the three packages makes the issue go away. I tried few other analyzer combinations and couldn't reproduce it except in this specific format. The reason I create this issue here first as opposed to Pure.DI or .NET is that the report shows this analyzer spending most of the time.

For reference, running the same use case under version 9.0.200:

Similar results under .NET 8 too.
