Debugging Windows Service Without Deploying It

At the beginning, there was no easy way to build a Windows service using Visual Studio and .NET Framework. Now that Microsoft has integrated this functionality as a template and a class library, it's much more easy to do that. This is good, but to test your newly created service you have to deploy it. That means you must add an installer and build a whole MSI file and run it in your environment. Once deployed, you can start it with Windows Service controller and attach a debugger to it.
