Access denied in RegisterActor #34

Closed pvivera closed 5 years ago

pvivera commented 6 years ago

I've created a simple app, just the template generated by Visual Studio for .net core, to test this package integration. But I'm experimenting a problem with the following code: 

private static void Main()
        {
            try
            {
                var builder = new ContainerBuilder();

                builder.RegisterServiceFabricSupport();
                builder.RegisterActor<TestingActorSystem>();

                using (builder.Build())
                {
                    Thread.Sleep(Timeout.Infinite);
                }
            }
            catch (Exception e)
            {
                ActorEventSource.Current.ActorHostInitializationFailed(e.ToString());
                throw;
            }
        }

The line builder.RegisterActor(); is throwing:

System.TypeLoadException: Access is denied: 'TestingActorSystem.TestingActorSystem'.

Any help?

Actor has to be public.

pvivera commented 6 years ago

@wasabii Thanks, it worked. I was trying to keep all actors internal as it mentions in this post. https://alexmg.com/posts/introducing-the-autofac-integration-for-service-fabric

@pvivera Does adding the following help for you?

[assembly: InternalsVisibleTo(InternalsVisible.ToDynamicProxyGenAssembly2)]

Closing due to lack of feedback. If this isn't resolved, we can re-open; or if there's more help needed I might recommend asking on StackOverflow.

Same issue; but with Stateless service
