Question

I am trying to acess a wcf service from a jQuery client

Specifically this example http://www.codeproject.com/KB/aspnet/WCF_JQUERY_ASMX.aspx#4

All works well

Answer 1

Typically, you won't be able to; modern browsers restrict this to prevent cross-site scripting attacks. One way around it may be to use "padded" JSON, JSONP, which inserts the results in a script element on your page. There's a Microsoft WCF sample here which seems to do that.
