Co-hosted silo not loading grains

[mariuszklos]

Hello,

I have aspnet core project with Orleans 7.1. I keep on getting error "ArgumentException: Could not find an implementation for interface"

this is my app init code:

var builder = WebApplication.CreateBuilder(args);        
      var host = Host.CreateDefaultBuilder(args)
          .UseOrleans((context, siloBuilder) =>
          {
              siloBuilder.UseLocalhostClustering()
              .AddMemoryGrainStorage("some-name-here")
              .ConfigureLogging(logging =>
              {
                  logging.AddConsole().SetMinimumLevel(LogLevel.Debug);
              }) ;                
          })
          .UseServiceProviderFactory(new AutofacServiceProviderFactory())
          .ConfigureWebHostDefaults(webHostBuilder =>
          {
              webHostBuilder
                  .UseContentRoot(Directory.GetCurrentDirectory())
                  .UseIISIntegration()
                  .UseStartup<Startup>();
          })
          .Build();

      host.Run();

and this is how I am trying to get a grain and getting the exception:
var chatGrain = GrainFactory.GetGrain<IChatGrain>(chatId);
where
GrainFactory is IClusterClient
Grains are in a separate project and added as a reference to the web project.

Which packages are you referencing in your application?

• All clients should reference Microsoft.Orleans.Client
• All silos (servers) should reference Microsoft.Orleans.Server
• All other packages should reference Microsoft.Orleans.Sdk
