Update the web.config file to move an ASP.NET 2.0 Site to ASP.NET 3.5
The forthcoming renovation of my personal Web site requires LINQ support and therefore I need ASP.NET 3.5. My hoster, ServerIntellect (highly recommended) announced that it had upgraded the web servers so I thought everything was in place. To confirm that ASP.NET 3.5 was working, I posted a quick test page that, you guessed it, refused to compile even though it ran fine on my development machine.
Here's the error: "Compiler Error Message: BC30205: End of statement expected."
To make a long story short, it turns out that there's a lot of new stuff you must have in the web.config file to support ASP.NET 3.5.
I ended up renaming the existing web.config, adding a new 3.5 version to the project, and copying it up. Sure enough, the strange errors went away.
