What is a Data Source?
A Data Source is simply the content that you want to display in each section of your app – YouTube videos from your favorite channel, your store’s inventory, images from your Flickr account, etc. Data Sources are displayed in your app through Sections. Every Section you create is connected to a Data Source.
What can I do with a Collection?
A Collection is a Data Source that allows you to upload data that does not depend on a website such as – store inventory, contact info,a daily menu, favorite musicians, etc. Before entering any data in a Collection, you can define the total possible columns of data. Add a column for every bit of information you want to display for each item and select what type of data it is. There are many types of information you can add: Address, Album Name, Artist Name, Image, Int, E-Mail, Phone Number, Song Name, and String. Changing the data type for each piece of information is important because it allows you to include a variety of additional actions in your app. Your data can be static or dynamic.
What does "Bind to data" mean?
When you start editing a page in your app, you’ll see a bind to data icon () next to each Content item. Binding means you connect part of a Data Source to a certain area of a page. You can see the options that are available for each Content section by clicking on the binding icon and hovering over Data.
What does "Add an Action" mean?
When you start editing a detail page that depends on a Collection with certain data types, you’ll see a small add an action lightning bolt icon () for each Content item. An action is something that will occur on your phone when you click on that piece of information in your app – call a number, send an email, etc. There are a variety of possible actions, but keep in mind that only the actions that correspond to the types of data in your Collection will appear.
When you create an app, you can easily change the default language that will be displayed in the Windows Store in the first "App Information" step. In order to add additional languages to your Windows Phone application, you need to download the source code for the application and edit it using Visual Studio.
The initial resource file you use to capture UI strings that are being localized is called AppResources.resx and is located in the app’s Resources folder of your project.
On the project’s Properties page in the Supported Culture box, select the language(s) you would like your app to support. Visual Studio will create a new resource file for each supported language that is an exact copy of the default language resource file (AppResources.resx). It will automatically rename it using the culture’s locale code, such as AppResources.en-US.resx.
Replace the default language values in each supported language resource file with translated values, and you are done!
