I have upgraded from ESRI 1.2 API to 2.0 api, including installing silverlight tools 4 and visual web developer 2010. Everything looks OK so far but I tried upgrading the ESRI API references and I don't get the namespace "http://schemas.esri.com/arcgis/client/2009". The references to the 2.0 api don't show up under the .net tab in the add reference dialog, I have to browse for them, only the references for the 1.2 api show up. When looking at the properties for the ESRI.ArcGIS.Client reference in my project, the version shows as 2.0.0.314, but I don't seem to have any of the new functionality, including the above namespace. Is there something else I'm missing, I've double checked everything and cant seem to find anything I've done wrong. If anyone can point me in the right direction, I would really appreciate it.
