I discovered the problem when I got a suggestion to use the System.Web.HttpUtility class for a certain task.
Looking at the documentation, I should have about 50 classes in System.Web, but I have only these:
AspNetHostingPermission
AspNetHostingPermissionAttribute
AspNetHostingPermissionLevel
I make this assumption since they are the only ones showing up in intellisense, and I get build errors when trying to use any other classes than these three.
I'm using .NET 3.5 SP1, and in the reference dialog it says i have version 2.0 of the System.Web component.
I'm lost. What could be wrong?
