Version Used: I don't know how to check it.

I noticed that there is a difference between .NET 7 and .NET 8 in terms of what IDE0200 reports and I think it is a bug, since .NET 8 performs worse.

Steps to Reproduce:

<TreatWarningsAsErrors>true</TreatWarningsAsErrors>

editorconfig:

csharp_style_prefer_method_group_conversion = true:warning
dotnet_diagnostic.IDE0200.severity = warning

global.json – if I change version to 7.0.100, it breaks the build. But for 8.0.100 it doesn't.

{
  "sdk": {
    "version": "8.0.100",
    "rollForward": "feature"
  }
}

code:

public class Repro
{
    private readonly MethodProvider _methodProvider;

    public Repro(MethodProvider methodProvider)
    {
        _methodProvider = methodProvider;
    }

    public void Main()
    {
        int[] numbers = { 1, 2, 3, 4, 5 };
        string[] asStrings = numbers.Select(x => _methodProvider.ToStr(x)).ToArray();
        Console.WriteLine(asStrings.Length);
    }
}

public class MethodProvider
{
    public string ToStr(int x)
    {
        return x.ToString();
    }
}

Notes:

1. I couldn't reproduce it with a simpler example where the called method would be in the same class.
2. The list of installed SDKs on my PC: 6.0.417, 7.0.404, 8.0.100.

Diagnostic Id: IDE0200

Expected Behavior: analyzer reports

Actual Behavior: analyzer doesn't report
