A lot of workarounds exist to debug the
OnStart method of a service. A straight way with
Debugger.Launch() is described in How to Debug a Windows Service. But what if this wouldn't work, e.g. on Windows Vista x64? This sample shows a simple method to attach the debugger to the service process and debug the
How It Works
The service process should wait till you have attached the debugger. The service process should not timeout. Just look at the code, it's quite easy.
Using the Code
All you have to do, is to copy this code snippet in your
Onstart method of your service class (derived from
protected override void OnStart(string args)
Start the service as usual. The service will wait until you attach the debugger to the service process. You can set breakpoints in your start code and debug it.
