Setup in c#.net 2005(Window application)

Question

I've done 2 window projects in c#.net 2005.And its going ok.But what i've problem now is anytime i made changes i have to modify my setup & deployment project as well.Is there any other way to generate exe file for end users which could be used after compiling/building the project(without using setup& deployment).
Also i would like to know about the server name & database name to be changed in app.config file while using at users.i.e sometime had to test with test database(similar database in different server for testing purpose).its very important to me & early response from any is appreciated.
thanks

If you modify anything inside the application you need to build it and create the setup again. If you need to modify the connection string for your test db then just open the app.config and give proper connection string for your db which includes server namedb name user name and password.
