In this white paper we will cover how to use the SDK to display weather conditions for cities across the United States. The real-time weather data will be retrieved using the WeatherBug API and shown on the map. We will animate the weather conditions (a glowing sun for Sunny conditions, a raining cloud for Rain, etc...) and cover some core concepts along the way, specifically use of a Controller mechanism in your Silverlight projects, parsing XML into your own data model that can be returned from a Web Service, and of course getting up to speed with the Bing Maps SDK for Silverlight.http://www.mknopf.com/articles/creating-a-weather-map-using-the-bing-silverlight-map-sdk-and-weatherbug.htmlWed, 23 Dec 2009 19:55:08 GMT2009-12-23T19:55:08Creating a Weather Map using the Bing Silverlight Map SDK and WeatherBugBuilding Silverlight application takes time, effort, patients, and tools (yes, you have to have some tools). In this post we will cover: where to get the necessities and some useful additional tools, as well as straight talk about the awesomeness, disadvantages, and difficulties of building Silverlight applications.
