 > 💡 This sample relies on a few assumptions. The default listening port for an ASP.NET Core web project is 5000, which is being passed to `dapr run` as `--app-port 5000`. The default HTTP port for the Dapr sidecar is 3500. We're telling the sidecar for `MyActorService` to use 3500 so that `MyActorClient` can rely on the default value.
