Hello, I have a couple of applications written in C#. These applications are installed on several machines. Whenever i make a change to an application i have to re-install the application on each machine. I was thinking of making an Update Manager. The Update Manager will check for updates and download and install new versions of the software automaticly.

How would i do this? Is it possible to update software by replacing some of the Application Manifests files / DLLs?

What I really want to know is this:
How do you use the update feature built into Visual Studio? When you publish your application it asks you if you would like to specify and update location. What would you place in that location? The folder of the new version of the application? If and update is then found would it be downloaded and installed automaticly without user interaction?
