c# - Can't use JavaScriptSerializer in Windows Universal Application -

i have prototyped getting json data web service in visual studio 2017 c# console application, deserializing json data 3 strings. moved code windows 10 universal application.

the deserialization code won't compile in uwp program because type javascriptserializer not available. i'm unable add system.web.extensions system (references/assemblies/framework), getting message vs 2017, "no framework assemblies found on machine," when windows 10 solution open.

here json string:

{      "snippet":"\"special counsel ...\"",    "snippetdate":"9/9/2017 12:00:00 am",    "snippetsource":"the washington post" } 

here code snippets compile , run on console project not windows 10 project.

using system.web.script.serialization; . . .      public class newssnippet     {         public string snippet { get; set; }         public string snippetdate { get; set; }         public string snippetsource { get; set; }     }  . . .  var serializer = new javascriptserializer(); var deserializedresult = serializer.deserialize<newssnippet>(jsonstring); 

what alternatives there deserialize json string in universal windows application?

you should able add newtonsoft's json.net via nuget

var deserializedresult = jsonconvert.deserializeobject<newssnippet>(jsonstring); var source = deserializedresult.snippetsource;
