WebRequest webRequest = WebRequest.Create(url + "StockInformationHandler.ashx?{\"Type\":\"getstockprice\",\"arr\":\"" + string.Join(",", isins) + "\"}");
WebResponse webResponse = webRequest.GetResponse();
Stream responseStream = webResponse.GetResponseStream();
MemoryStream memoryStream = new MemoryStream();
responseStream.CopyTo(memoryStream);
JavaScriptSerializer ss = new JavaScriptSerializer();
return ss.Deserialize<list><symboldata>>

Solution 2

There is not need to convert anything specifically: Framework 4.0 is backward-compatible with 3.5. In your assemblies, you can change the target. If you open 3.5 solution with VS 2010, the solution and all project files will be converted automatically, with your permission.
