Are you building this project against a Client Profile version of the .net framework if so System.Web is not included in the profile.

To check this simply select the project, right click and select properties, on the application tab there is the target framework, try switching this to framework 4 opposed to framework 4 client profile.

Hope that helps

Since yuo are creating a WinForms application, System.Web isn't included by default.

Right-click your project, choose "Add Reference". In the dialog that appears, scroll down to System.Web; select it and hit "OK".

To add to what carl_tawn said:

Right-click your project, choose "Add Reference".

Make sure that you are on the ".NET" tab in the "Add Reference" dialog.
