Windows 8 Store App development

For creating a package, you build the app with no errors and go to the menu Project ->Store ->Create App Package. Then you are prompted with a window shown below:

Here for creating a package for testing in a tablet, choose the No option and proceed and so you dont need a Windows Store Account.

But for creating a package to upload in store, choose the Yes option and login with your Store account.
After the package is created successfully, it will be created in a folder called AppPackages in ur app. double click it and you will find a file with .appxupload extension, you have to upload that file in the Store.
