C# Browser Application Error

When I try to run I get "Unable to install this application because an application with the same identity is already installed. To install this application, either modify the manifest version for this application or uninstall the preexisting application" in log file. How can i fix this?

the source of your problem is running the application from multiple URLs outside of the VS debugging environment.  The "quick fix" for your problem is to open up an SDK command prompt and run "mage.exe -cc" every time you need to run what is basically the same identical application from a different URL.  This will solve the problem.
