I have a strange problem and am wondering if anyone has any ideas on how to fix my problem. I have several projects written in ASP.NET 1.1 using Visual Studio 2003. I recently upgraded one of them to ASP.NET 2.0 using the built in wizard in Visual Studio 2005, then converting it into a web application.
My issue is that for some reason, the project still seems to be using all the .NET 1.1 dlls, especially when using Intellisense.
For example, I was going the code and trying to clear out obsolete methods, one of which is ConfigurationSettings.AppSettings("XXXXXXXX") and changing it to System.Configuration.ConfigurationManager.AppSettings("XXXXXXXXX"), however intellisense does not seem to see the ConfigurationManager as a member of Configuration (as it should in the 2.0 framework).
So, thinking the IDE still thinks the project is running .NET 1.1, I went and deleted all references in the project, then reset them and made sure all the references pointed to 2.0 dlls. That doesn't seem to work either.
I also checked the actual project file and opened it in Notepad to make sure there were no lingering 1.1 references, but didn't see anything strange.
Anyone have any ideas?
