Chart control in VWD 2010 express

Hi,

I have some troubles to get the Chart control to show in the toolbox in my VWD 2010 Express for a specific site.

The site is originally a .net 2.0 but should be 3.5 now (according to property page), the IIS is running .net 3.5 as well. When I load a new site into VWD, the cart control do show – so I guess the control is known to VWD ? Looking at the web config file, the very first line is:

 <configurationxmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0">

I have tried to change that to 3.5, but it did not make any difference

Any suggestions out there ?

Best regards
