How can I inject Iconfiguration?
public override async Task OnApplicationInitializationAsync( ApplicationInitializationContext context) { await context.AddBackgroundWorkerAsync<PollingWorker>(); }If I add an IServiceProvider I get this error

What is your
PollingWorkerclass? You can inject services on the constructor or method context.
