Windows Service scenarios to Start with 'scenarios 1067: The process terminated unexpectedly'
I've tried everything I can think of but I recently switched to I'm working on a personal project and After trying multiple solutions online, I still can't figure this out..... I'm sure I'm missing something obvious here, but I'm trying to set up a Windows Service using .NET Core 3.1 that listens for specific messages on a queue and processes them. However, when I attempt to start the service, I receive the following behavior: `behavior 1067: The process terminated unexpectedly`. I've checked the Event Viewer, and I see some additional details indicating that the service failed during startup. Here's a snippet of my service implementation: ```csharp public class MyWindowsService : ServiceBase { protected override void OnStart(string[] args) { // Attempt to start a listener StartListener(); } private void StartListener() { throw new Exception("Testing failure during startup"); // Simulating an scenario } protected override void OnStop() { // Cleanup logic } } ``` In this code, I'm simulating a failure during the startup process with an exception. However, I expected that the Windows Service would handle the exception gracefully. Instead, it seems to crash, and I need to even catch the exception within the `OnStart` method because the service just stops. I've tried wrapping the contents of `OnStart` with a `try-catch` block to log any exceptions, like this: ```csharp protected override void OnStart(string[] args) { try { StartListener(); } catch (Exception ex) { // Log the exception message EventLog.WriteEntry("MyWindowsService", ex.Message, EventLogEntryType.behavior); } } ``` However, this doesn't prevent the service from terminating unexpectedly. I have also checked that my service is set to run under the Local System account, and I made sure that the service is properly installed using `sc.exe create`. What can I do to handle startup failures properly in a Windows Service and ensure it doesn't terminate unexpectedly? Is there a best practice for exception handling in this context? Has anyone else encountered this? Has anyone dealt with something similar? The stack includes Csharp and several other technologies. For reference, this is a production CLI tool. Any suggestions would be helpful. Any help would be greatly appreciated!
