Get the status of the publish/install WPF apps in known machines.

I have a WPF app with MVVM pattern and having entity framework is built. If the app is installed in different known machines then need to know the status(means each machine is running the WPF app or not) for every 5 minutes.

Hi,@ SANTHOSH B. Welcome to Microsoft Q&A. You could try to implement a centralized server-client architecture where each installed WPF app periodically sends a heartbeat signal to the server. The server keeps track of the status of each client and can provide this information upon request.

Heartbeat Mechanism in WPF App:

Modify your WPF app to periodically send a heartbeat message to a central server. This can be done using a background thread or a timer. The heartbeat message should include information such as the machine's ID, app version, or any other relevant details.

// Example of sending a heartbeat using HttpClient private async Task SendHeartbeat() { using (var client = new HttpClient()) { var machineId = GetMachineId(); // Implement a method to get a unique identifier for the machine var version = GetAppVersion(); // Implement a method to get the app version var data = new { MachineId = machineId, AppVersion = version }; var response = await client.PostAsJsonAsync("https://your-server.com/api/heartbeat", data); // Handle the response if needed } }

Central Server:

Implement a central server that exposes an API to receive heartbeat messages. The server should keep track of the last time it received a heartbeat from each machine. You can use a simple database or in-memory data structure for this purpose.

[HttpPost("api/heartbeat")] public IActionResult ReceiveHeartbeat([FromBody] HeartbeatData data) { // Update last heartbeat timestamp for the machine identified by data.MachineId // Store or update this information in a database or an in-memory data structure return Ok(); }

Monitoring and Notification:

Implement a monitoring component on the central server to periodically check the last heartbeat timestamp for each machine. If a machine has not sent a heartbeat within a specified interval, consider it as not running.

You can also implement notifications (e.g., email alerts, logs) to inform you when a machine has not sent a heartbeat for a certain period.

Security Considerations:

Ensure that the communication between the WPF app and the central server is secure. You may want to consider using HTTPS for the API and possibly adding some form of authentication.
