Changing the name of a namespace

Question

Another newbie question. I wrote a word processing application which began as just an online school class exercise which just kept on growing until I now have something I'd like to publish and share with family and friends. The namespace for my project began as "Lesson9Prog1" and that's the name it still has. I ran a publishing test and then installed it via the setup.exe program. Now I have an application installed called "Lesson9Prog1". For obvious reasons, this is not the name I want my installed application to have. I'd like to know how I can publish my application with a name such as "Bob's Word Processor" or something similar. Can I just go into the program and change the name of the namespace without screwing everything up or will MS Visual C# Express edition make all the necessary adjustments to the project if I do that? How can I publish my app with a name that's different than the namespace? THANKS!!
