arcgis 10 blank map

ThaoNguyen

I just installed arcgis view 10 to my machine.  Created a map in MS Visual Studio 10, when I viewed it, it was blank, I could see 1 tooltip but the map was not there .  I connected to a map service in arcgis server 10.  I was able to connect to a map service in server 9 and the map was displayed fine.  The map service in server 10 was available since I could view the details from browser (http://<server name>/arcgis/rest/services/......)
Please help!
Thanks!

BTW, we are using .net framework 4. My machine is Windows 7 Enterprise.  I think it would be OK.
This is a desktop app using acrgis wpf APIs for map.

Found the problem!
I added a map navigation, I had a problem with the map navigation that the zoom bar was not displayed as I expected.  I was told to specify maximum and minimum resolution values.  I specified max as 2 and min as 0.000001 and the zoom bar was displayed as expected.  For esri 9, my map was displayed as expected as well.
When I move to esri 10, if I leave the same resolutions values, the map zoom in too close that I only see the graphic color that I set, no streets etc.  When I remove resolution attributes, my map is zoomed out as expected, but my zoombar is too short.

Now, my problem is I don't know what resolution I should set so that it works on both arcgis 9 and 10 😞 and I can see my zoom bar as expected (same height as the round navigator).
