Map doesn't exist in the namespace

[BenSher1]

I'm testing a wpf/engine application and referencing the map namespace, but i get the error the name"Map" does not exist in the namespace "http://shcemas.esri.com/arcgis/client/2009

Could you please provide which version of the .Net Framework and the ESRI API you are using in your WPF application?

[BenSher1]

3.5 .net and 2.1 for silverlight api

This issue usually happens when you use the DLLs built for .Net Framework 4.0 in a .Net Framework 3.5 WPF application. Make sure you are using ESRI.ArcGIS.Client.dll file that is built for .Net Framework 3.5.

Thanks, that was it, just changed to point my project to .net 4 and we're good.
