Hello argoo,

Thank you for your inquiry.
The 'Profile=Client' is what is causing this. System.Web is not part of Client profile .
Target full framework in VS and you should be fine.

Try to do following step,
Changing the Target .NET Framework for C#
1.On the Project menu, click ProjectName Properties.
2.Click the Application tab.
3.In the Target Framework list, select .NET Framework 4.0 , I guess that item of .NET Framework 4.0 Client Profile has been

Please let me know if you have any questions and concerns.

Hi, There.
I'm developing using .net 4 client profile, not full framework.
Is there version that support .net 4 client profile or lower?
I tried the version in net2.0 and net3.5 but they seem identical to net4.0
Please help. If it doesn't support client profile, I may have to look for different solution.

Dear chris,

Generally, we need to provide web application functionality, so our product does not support client profile framework.
But we could provide a version to support client profile framework specially to you. In that case, you should purchase a license at first, and then we will generate a special version for you within 12h. I am sure you appreciate that.
