ASMX web service is not returning JSON data in IIS7

This code was perfectly working and returning json data when was being called from Jquery in IIS 5-6.However when it was deployed to IIS7, it was constantly returning xml response.


 

[WebService(Namespace = "http://tempuri.org/")] 

[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]

[System.Web.Script.Services.ScriptService]

 public class SomeService : System.Web.Services.WebService

 { public SomeService()

 { //Uncomment the following line if using 

designed components //InitializeComponent(); }

 [WebMethod] [System.Web.Script.Services.ScriptMethod

(ResponseFormat = ResponseFormat.Json)] 

public List<sometype> getlist2() 

{ List<sometype> localtaglist =

 new List<sometype>(); ... foreach (...) 

{ sometype localtag = new sometype(); ... localtaglist.Add(localtag); } 

return localtaglist

 }


Add following lines of code to the web method and it will successfully 

return data in json format.

Context.Response.ContentType = "application/json"; 

JavaScriptSerializer jsonSerializer = new JavaScriptSerializer();

 Context.Response.ContentType = "application/json"; 

Context.Response.Write( jsonSerializer.Serialize(localtaglist));

this error.

 

to solve this issue  , set allowDoubleEscaping to true in web.config file.
