The analyzer assembly references version '4.6.0.0' of the compiler, which is newer than the currently running version '4.5.0.0'

I’m working on a non-public project. I can provide a repro and/or binlog via Teams.

Having moved to the latest .NET SDK from:

{
  "sdk": {
    "version": "8.0.100-alpha.1.23061.8"
  },
  "tools": {
    "dotnet": "8.0.100-alpha.1.23061.8"
  }
}

…to

{
  "sdk": {
    "version": "8.0.100-preview.2.23115.11"
  },
  "tools": {
    "dotnet": "8.0.100-preview.2.23115.11"
  }
}

I’m no longer able to build:

Build FAILED.

Sometimes the NuGet package ships faster than the .NET SDK.

I’d consider that super niche scenario though that we do not support. It might mean some IDE features are broken.

I hit this trying to build an older branch of the .NET SDK because the global.json from arcade was pinning to an older assembly version. Anyone else who hits this with a dev sdk should try to update their eng folder to match main if using a newer preview SDK.
