I have a web site that vs 2008 seems to think is not an ASP.NET 2.0 web site, at least the asp:xxx controls are not recognized. This worked a few weeks aog, but now does not work. I ran a complete repair of VS 2008 and the problem persists. Other web sites are fine. Is there some flag that got messed up in the properties? When I look at the properties, it says the target framework is 2.0.
