I need setup for a WCF service as follows:
1. Setup should install WCF service in Windows Service environment at target machine
2. There should be an interface in Installer that will populate all SQL Server instances installed at client. Provision to enter User Name, Password and to test connection
3. After user tests connection, WCF service config should be modified based on selected parameters (Server, database, username and password).
4. After config change start service
Please describe tool and approach
