I'm using the WPF assemblies from the freely downloadable ESRI WPF/Silverlight 2.0 SDK.
As I type in a "using" statement in visual studio, I can use intellisense to expand out into:
using ESRI.ArcGIS.Client.Tasks.Utils.JSON;
However, I don't see any documentation for it, nor does anything show up in the object browser.
Does anyone know where I can find more out about this?
