TopicDescription

Connection usage data

Consider the following recommendations when using Windows Runtime Network Information APIs in your connected app.

Custom data formats

Users share a variety of information when they're online. Successful apps take the time to analyze the types of information that users are most likely to share with others, and package that information so that the receiving apps can process it correctly. In many cases, the information users want to share falls into one of the six standard formats that Windows supports. However, there are some instances in which having a more targeted data type can create a better user experience. For these situations, your app can support custom data formats.

File types and URIs

By understanding the relationship between Windows Store apps and the file types and protocols they support, you can provide a more consistent and elegant experience for your users.

Login

Many Windows Store apps provide a personalized or premiere experience to users when they're logged in. Some apps require the user to log in to a registered account to get value from the app. Other apps provide a rich baseline experience for all users but enable enhanced features when the user is logged in.
