i have just upgraded a test copy of my site to asp.net 4.0 and have noticed a strange issue that only arises when i upload the site to my server.
the site has an asmx web service that returns json, yet when i run the site on my server it returns xml. it as been working fine in asp.net 3.5 for over a year.
the webMethod is decorated with the correct attributes...
[WebMethod][ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public List<LocationRecentChange> RecentChanges()
and on my local machine it returns json.
yet on the server (Windows 2008 64bit) it returns xml.
using firebug console you will see a 200 OK response and a bunch of XML, and on my local machine the data returned is the JSON i expect.
Here is the javascript that calls the service..
function loadRecentData() {
$.ajax({
type: "POST",
url: "service/spots.asmx/RecentChanges",
data: "{}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: loadRecentUpdates,
failure: function(msg) {
//alert(msg);
}
});
}
Any suggestions welcome, this has got me stumped!
Are you sure .NET 4 is installed on your server?
The ScriptHandlerFactory's "type" string in .NET 4 is:
System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
ASP.NET 4 now includes that in its default web.config at the machine level. So, you shouldn't need any mapping to the ScriptHandlerFactory in your project's web.config, 3.5 or 4.
