Jesse MacFadyen resolved CB-938.
--------------------------------
Resolution: Won't Fix
This is a limitation of the Silverlight JSON serialization, adding a 300 kb
library dependencies is not a reasonable solution.
Working around the specific issue mentioned involves url encoding the
FileTransfer params object, it can simply be passed as a string.

> [WP7] Passing more complex objects over the bridge... Currently won't work.
> Basically the DataContractJsonSerializer .NET object that we employ to parse
> JSON on the native side can't parse nested objects in JSON. The DataContract
> stuff is supposed to make it easy to cast the various JSON values to .NET
> types. In the case of a nested object with dynamic keys, that you can't model
> ahead of time, we tried using a Dictionary type on the native side. This
> won't work [1].
> This came up when deserializing FileTransfer upload options because they have
> a nested "params" object that house dynamic &key=value URL parameters to send
> with the HTTP request. Not sure if it happens in other spots.
> Anywho, one potential solution is to explicitly convert nested objects such
> as these to a dumber structure. In the SO thread [1] they suggest having an
> array of {key:"known1",value:"foo"} pairs replace the objects.
> The native side could parse that.
> Another option is to use the JSON.net library [2]. MIT license. 300-ish kb
> .dll.
> The stock System.Json namespace that is available in .NET and has better
> capabilities is not available on Windows Phone.
> Any other solutions/ideas/comments/thoughts?
