Introduction to the open-source program of classic Windows Phone 7-positioning-based social networking application Foursquare

Currently, geographic location-based systems are getting increasingly popular in China. For example, even Vanke chengpin has begun to use advertisements on bus stops to sign in. As a pioneer in such applications, Foursquare has to mention it abroad. This is a location-based social network service. Its functions are very interesting, that is, when a user arrives at a store or place, you can use your mobile phone to register your location on the Foursquare website, and publish your location on popular social networking platforms such as Twitter and Facebook.

 

 

 

In addition. You can also view comments from other users on Foursquare, and add users who have logged on to this location as friends. If a friend is nearby, Foursquare will send a message to the user. The most important thing is Foursquare's reward mechanism. If a user registers for a certain number of times, the user will enjoy discounts and discounts for the seller.

 

Traditional location services (such as local search) have been struggling on the line of life and death, while Foursquare is obviously a more integrated location service with greater commercial value. The user's prize is the credit of the merchant. The Merchant can also send marketing information to the registered user. The traditional location service only helps users find sellers, while Foursquare enables users to interact with sellers, so that sellers can define and understand registered users and have their own user groups, this is more meaningful to sellers.

 

This Windows Phone 7 Foursquare application is developed based on C # And Silverlight, and Microsoft's Bing map service is used as the map engine in the background. Foursquare can be regarded as a typical example of the Windows Phone 7 series based on geographic location services and real-time data feedback.

 

Currently, this application is open-source,CodeAt present, although only Microsoft Visual Studio 2010 express for Windows Phone beta is supported, there are still many things worth learning. It strictly adopts the mvvm mode, so the entire code is very clear. If you have applications related to geography, go to http://4square.codeplex.com/to download the code.
