Creating a patch to upgrade .NET application

• Overwrite the old files with the new ones

Answer 1

If you already use a a VS Setup Project you can deploy the new version of this project and it will upgrade existing installations. Have a look at the setup and upgrade ids. The stop and start of the service can be done by custom actions that can be defined in the project and will be executed i.e. when your setup is committed or rollbacked etc.
