After my CPU's updating, I re-opened a couple of SL projects developed several months ago. Each pf the projects shows a long error lists. E.g. the "ESRI.ArcGIS.Client does not exist in the namespace 'System.Windows' (are you missing an assembly reference?)". In my References folder, the ESRI.ArcGIS.Client (v4.0.30319) is there, sourced at my projetc's \bin\debug\ folder. I know these errors are Version-related. How can these be fixed? Thanks.
From http://support.microsoft.com/kb/2516078, it mentions: The sum of the following two path length is exactly added up to 259 characters (= MAX_PATH �?? 1) 1) The path of a referencing project�??s directory. 2) The relative path to a referenced project from the current directory (= a referencing project�??s directory). Does anyone know how to detect and then fix it? Thanks.
