Changing an application's name
I got the following error from Microsoft when trying to submit my app to the Marketplace,
The application's name on a device is a generic name "SIXnaApp3", and does not accurately represent the application.
Right now SIXnaApp3 is my project name. I cannot figure out how to change the application name to meet Microsoft's submission requirements.
In solution explorer, Expand the node properties and Open the WMAppManifest.xml file and change the Title of the app. Add things like description,author,company. The following screenshot might help you.
And this title will change the app name at app menu. If tile menu name is to be changed means, Right click on the project name and go to properties. Change the tile name there.
Solution Explorer > (Right Click)properties > Tile Title
