The type 'T' cannot be used as type parameter 'T' in the generic type or method 'ServiceProviderServiceExtensions.GetRequiredService<T>(IServiceProvider)'. Nullability of type argument 'T' doesn't match 'notnull' constraint.

The type 'GreenDonut.IDataLoaderDiagnosticEventListener?' cannot be used as type parameter 'TService' in the generic type or method 'ServiceCollectionServiceExtensions.AddSingleton<TService>(IServiceCollection, Func<IServiceProvider, TService>)'. Nullability of type argument 'GreenDonut.IDataLoaderDiagnosticEventListener?' doesn't match 'class' constraint.

Converting null literal or possible null value to non-nullable type.

Nullability of reference types in return type of 'lambda expression' doesn't match the target delegate 'Func<IServiceProvider, IDataLoaderDiagnosticEventListener?>' (possibly because of nullability attributes).

Possible null reference return.
