I'm installing a brand new site using DNN 5.2.0 on a fully patched Windows 2008 r2 server. So it's running IIS 7.5. I understand the AppPool identity stuff and that is all correctly configured.
I have setup up the site, the folders, given permissions to the app pool identity, created the database, all that and now its time to run the wizard to complete the install and this is the error message I get.
Parser Error Message: Could not load file or assembly 'System.Core, Version=3.5.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies. The system cannot find the file specified.

Which would seem to indicate that it cannot find the asp.net 3.5 files? but asp.net 3.5 sp1 is installed by default as part of the asp.net feature in the web role for windows server 2008 r2.
I am sure this must be something trivial that I have missed. I have a 5.1 DNN site running on this box just fine. Can anyone offer a suggestion for how to fix?
