ASP.NET Web Application Target Framework 3.5, but Development Server Version Information says 2.0?

I set the Target Framework for a Web Application to .Net Framework 3.5, but when I get a YSOD, the "Version information" at the bottom of the page says "Microsoft .NET Framework Version:2.0.50727.5448; ASP.NET Version:2.0.50727.5420"

I've replicated this on a File > New Web Application as well, so I can conclude that I'm not doing anything out of line in my code.

Does anyone know why this is, or how to fix it?

Solution

  • This is the expected behavior. .NET 3.5 is just .NET 2.0 SP2 with some new assemblies.
