-> `dotnet_style_namespace_match_folder` requires the analyzer to have access to project properties to function correctly. For projects that target .NET Core 3.1 or an earlier version, you must manually add the following items to your project file. (They're added automatically for .NET 5 and later.)

-> <ItemGroup>
