Yale,
Thanks for your response. I’m using the map control DesktopEdition.dll ver. 3.0.362.0 and MapSuiteCore.dll ver. 3.1.182.0. The ZedGraph.dll version is 5.1.4.31904 and ZedGraphStyleExtension.dll ver. 3.0.362.0.
I tried the HowDoI sample solution for ZedGraph and it works fine in that solution but the same does not work in my test WPF solution. Here’s the code from my test solution:
Window1.xaml code:
<Window x:Class=“MapSuiteTest.Window1”
xmlns=“schemas.microsoft.com/winfx/2006/xaml/presentation”
xmlns:x=“schemas.microsoft.com/winfx/2006/xaml”
xmlns:my=“clr-namespace:ThinkGeo.MapSuite.DesktopEdition;assembly=DesktopEdition” Loaded=“Window1_Load”
Title=“Window1” Height=“749” Width=“1010”>
<Grid>
<my:WpfMap x:Name=“wpfMap1” Margin=“24,22,0,0” HorizontalAlignment=“Left” VerticalAlignment=“Top” Width=“950” Height=“650”></my:WpfMap>
</Grid>
</Window>

Window1.xaml.cs code:
NOTE:- All instances of wpfMap1 give the error ‘The name wpfMap1 does not exist in the current context’

NOTE: If I remove the references to the ZedGraph.dll & ZedGraphStyleExtension.dll in my project and comment out all the ZedGraph related code above, the map control runs fine.
Appreciate your help!
