You need to use type.GetTypeInfo(), which then has various GetCustomAttribute methods (via extension methods), or there is .CustomAttributes which gives you the raw information (rather than materialized Attribute instances).

If .GetTypeInfo() doesn't appear, then add a using System.Reflection; directive.

        <Version>4.3.0</Version>
    </PackageReference>
</ItemGroup>
