I created a asp.net web site with a web service in it.

My web service returns a object "Person" which is serialized into
JSON, when I make a ajax call to this service this is my return
output.

{"d":{"__type":"Person","FirstName":"Foo","LastName":"Goo","Age":
99,"Address":{"Street":"One Microsoft
Way","City":"Redmond","State":"WA","Zip":98052}}}

My Question is where did that "d' and "__type" come from and is there
a way I can get rid of those two.

I want my end result to be this.

{"FirstName":"Foo","LastName":"Goo","Age":99,"Address":{"Street":"One
Microsoft Way","City":"Redmond","State":"WA","Zip":98052}}

help is really appreciated. I am attaching a copy of the source code.
Nothing has been changed in the web.config.

Thanks,
Shailendra

"d" and "Person" might be name spaces / class names / other metadata of
the serialized object. IIRC this was the case when a Java object is
transformed to JSON using the Apache ActiveMQ message broker.

So how do I get rid of those? I just want the JSON to be plain without
any extra root nodes.

Thanks,
