Use System.Net.Http HttpClient in ASP.NET Core Web Application (.NET Core)

Hello,

I created a new ASP.NET Core Web Application (.NET Core) in Visual Studio 2015.

Does anybody know how to add the example code from here: https://msdn.microsoft.com/en-us/library/system.net.http.httpclient%28v=vs.110%29.aspx?f=255&MSPPError=-2147217396#Inheritance to a ASP.NET Core Web Application (.NET Core) solution?

Thanks,
Tony
