When I run an XBAP application, I get Application Deployment Error. What do I do to overcome this error ?

XBAP applications are cached when you run for the first time. In order to give maximum performance, subsequent requests run the application from the cache until the version number of the application is changed. Therefore, if you make any changes to the code, re-compile and then run it and you don’t see any changes to the result or if you get the application deployment error, run the ‘mage-cc’ command from the Visual Studio Command Prompt and try running the application again.
