Microsoft Orleans - Run Multiple Silos from a .NET Core Console App
If you are new to Microsoft Orleans and you are in a stage where you want to run multiple Silo from a single .NET Core console app, here is a way to achieve that.

My Silo Host project Program.cs Main method looks like below,
private static async Task Main(string[] args){ int siloPort, gatewayPort; try { siloPort = int.Parse(args[0]); gatewayPort = int.Parse(args[1]); } catch (Exception) { siloPort = 11111; gatewayPort = 30000; }
var invariant = "System.Data.SqlClient"; // for Microsoft SQL Server var connectionString = "Data Source=.;Initial Catalog=OrleansCluster;Integrated Security=True;Pooling=False;Max Pool Size=200;MultipleActiveResultSets=True";
var siloBuilder = new SiloHostBuilder() // Clustering information .Configure<ClusterOptions>(options => { options.ClusterId = "dev"; options.ServiceId = "ServiceApp"; }) .UseAdoNetClustering(options => { options.Invariant = invariant; options.ConnectionString = connectionString; }) .ConfigureEndpoints(siloPort: siloPort, gatewayPort: gatewayPort)
.ConfigureLogging(logging => logging.AddConsole());
using (var host = siloBuilder.Build()) { await host.StartAsync(); Console.ReadLine(); }}To run multiple Silo, we need to specify different set of ports for each. Here we are achieving the same via parsing the args.
Now you can run a Silo by executing following command on the Silo project root directory
dotnet run <siloPort> <gatewayPort>eg,
dotnet run 11111 30000dotnet run 11112 30001dotnet run 11113 30002
