Windows services might be a hell to debug if you implement them the classic way. An alternative is to host them in a console application (as shown here : http://stackoverflow.com/questions/7764088/net-console-application-as-windows-service). In the "main" routine, you check if an interactive user session is present. If so you are in console mode and you start/stop the WCF service in the main application. This implies you can debug easily. If not you are in service mode and the service will behave as needed. The debugger alwas launches in interactive user mode, so enabling debugging.

It will allow you to debug without a headache.

did you check the what is the run mode before deploying the service? sometime it behaves differently if you deploy 'debug' mode..ty with 'release' mode.

Hi,

Please try to check the reply from @Steven in: http://social.msdn.microsoft.com/Forums/en-US/92fe50b0-495d-42e7-ab86-6314fdc49cd8/windows-service-doesnt-hit-onstart-method with the following:

For normal windows service live debugging, we can use Visual Studio to attach the windows service process.

However, if you want to debug the "OnStart" event handler, then the default approach won't work. Since the OnStart will be called at the very earlier time when we start a windows service in the service management console. The following reference mentioned how we can simulate the OnStart execution and perform live debugging through this means:

See the windows event viewer, if any internal error occurs it logs to event viewer

this article will help you to host WCF service in Windows Service and diagnose issues
