Question

I’m learning how to build C#/XAML metro apps in Windows 8 and I was wondering if there’s a way to call RESTful services using the framework? I was able to with a JS/HTML5 app, but I am wanting to do this from C#/XAML.

Any help is appreciated.

You should be able to use System.Net.HttpClient and HttpRequestMessage.

Here’s a writeup for Consuming Json Data in WinRT

Basically, it’s used like:

HttpClient client = new HttpClient();
string url = "http://yourservice.com/some/resource";
HttpResponseMessage response = await client.GetAsync(url);
return response.Content.ReadAsString();

If you need to modify the request or get called during the pipeline of execution (add things like headers) you can use HttpMessageHandler.
