ActorSample

Actor Sample

The Actor sample shows how to create a virtual actor (DemoActor) and invoke its methods on the client application. The sample is a copy of the Dapr .NET SDK Actor Sample, but modified to include Dapr Sidekick integration for launching a Dapr sidecar.

See the original source for more information on the purpose of the sample.

How Dapr Sidekick was added

The main change to the template code to add Dapr support can be found in the ConfigureServices method in Startup.cs in the ActorSample.DemoActor project:

public void ConfigureServices(IServiceCollection services)
{
    ...
    // Add Dapr Sidekick
    services.AddDaprSidekick(Configuration);
}

Running the example

This sample requires a full initialized Dapr installation with both the dapr_placement and dapr_redis containers up and running. If this is not the case please follow the instructions to Init Dapr Locally.

Build the solution and set the ActorSample.DemoActor project as the startup, then run it in Visual Studio. The Dapr Sidecar will launch and the hosted actor will use it to registered with the placement service.

By default Dapr will search for the Placement service on port 6050 on Windows, or 50005 on other platforms. This is the port exposed by the dapr_placement container.

Navigate to the ActorClient build output directory at <RepoRoot>/bin/<Debug|Release>/samples/ActorSample.ActorClient/netcoreapp3.1 and run ActorSample.ActorClient.exe. This will connect to the same Dapr sidecar on port 3500 and submit calls to the hosted Actor.
