Hi Maulkye,
Just off the top of my head, does your JSON looks like this:
{
thingy: "value"
}
or like this:
{
"thingy": "value"
}
The former is not valid JSON syntax. It is valid JavaScript object
literal syntax, but not JSON, which is a _subset_ of object literal
syntax. The only primitive values (e.g., things you leave out of
quotes) in JSON are false, true, and null.
So if you're not putting quotes around the things on the left, you
might try that to see if it's the problem. Maybe the MS parser is
being picky.
HTH,
