问题 I am trying to pass in some simple JSON to an ASP.NET 4.5 Webmethod from jQuery. And it is not working quite the way I want it. It works if I accept the inputs as separate parameters: [WebMethod] public static Address GetJSonAddress(string name, string street) But if I try to take it as an object it does not work, what gets passed in is simply null: [WebMethod] public static Address GetJSonAddress(Address newAddress) I have tried Webmethods, Pagemethods, WCF using DataContractJsonSerializer..

I want to make sure that these methods execute asynchronously.

Before I dive directly into this I need
