Is there any way to connect Service Fabric Stateless service (in local) to my local WPF app? I would like to process some data on stateless service and send update to WPF app for example using NServiceBus
Yes, you can use a message queue for this.
Your stateless service would create a message and put it on the queue:
static async Task SendMessageAsync()
{
// create a Service Bus client
await using (ServiceBusClient client = new ServiceBusClient(connectionString))
{
// create a sender for the queue
ServiceBusSender sender = client.CreateSender(queueName);
// create a message that we can send
ServiceBusMessage message = new ServiceBusMessage("Hello world!");
// send the message
await sender.SendMessageAsync(message);
Console.WriteLine($"Sent a single message to the queue: {queueName}");
}
}
The WPF application would receive that message and process it:
// handle received messages
static async Task MessageHandler(ProcessMessageEventArgs args)
{
string body = args.Message.Body.ToString();
// update the ViewModel here
// complete the message. messages is deleted from the queue.
await args.CompleteMessageAsync(args.Message);
}
Instead of sending a simple string, I recommend sending a serialized object, e.g. using JSON.
