 ### Code Highlights
 Microsoft Computer Vision API provides a number of methods that allows you to analyze an image. Check out [IVisionServiceClient.cs](https://github.com/Microsoft/Cognitive-Vision-Windows/blob/master/ClientLibrary/IVisionServiceClient.cs) for a complete reference of the methods available. In this sample we are using `AnalyzeImageAsync(string url, ...)` and `AnalyzeImageAsync(Stream imageStream, ...)` to analyze an image from a URL and stream respectively. The `AnalyzeImageAsync` method returns [AnalysisResult.cs](https://github.com/Microsoft/Cognitive-Vision-Windows/blob/master/ClientLibrary/Contract/AnalysisResult.cs) class which contains rich information about the image:

 In this sample we are using the API to get the image description and send it back to the user. Check out the use of the `MicrosoftCognitiveCaptionService.GetCaptionAsync()` method in the [MicrosoftCognitiveCaptionService.cs](Services/MicrosoftCognitiveCaptionService.cs) class.
