Universal Windows project - HttpClient exception

I'm trying to implement REST client in Universal Windows project (in Windows 10 universal app) using HttpClient, but the following line:

var response = _client.GetAsync(address).Result;

throws an AggregateException with the following message:

Access denied. A network capability is required to access this network resource

More surprisingly, the request isn't event sent to server. How can I solve this problem?

Solution 1:

Double click on the Package.appxmanifest file in your project.
Click on the "Capabilities" tab. Add the Private Networks capability to your project.
