the JSON that is being emitted is being stored in a DB as an object state,
then fails to deserialize properly from that value. We've simplified it,
bypassing the database, encoding, etc and it still fails, however we are
serializing the exact same types in other areas of the application using the
same shared method and they all work just fine.

Here is the JSON that it is blowing up on:

"[{\"CLRTypeName\":\"DateTime\",\"Defaultvalue\":\"11\\\/22\\\/2008\",\"ParameterName\":\"StartDate\",\"ParameterType\":\"3\",\"ParameterValue\":\"\",\"Prompt\":\"Start
Date\",\"ValueList\":[]},{\"CLRTypeName\":\"DateTime\",\"Defaultvalue\":\"12\\\/22\\\/2008\",\"ParameterName\":\"EndDate\",\"ParameterType\":\"3\",\"ParameterValue\":\"\",\"Prompt\":\"End

ALL -\",\"3|SPARTANBURG REGIONAL HEALTHCARE SYSTEM -

And then we tried a simple XmlObjectSerializer for the same type and
recieved the same error (here's the object Xml string that was generated and
failed):

Finally, here is the error and stack trace we're getting back form the
deserializer:

Any help would be greatly appreciated.

OK, nevermind. Got this figured out. Turns out our DAL was re-serializing the
serialized JSON string going in, however was only attemptnig to deserialize
it once coming out, which caused the incorrect character (escape) to fail
because the first deserialization should have been to System.String.
