Getting Security Exception SQLCE 4, Code First CTP 5 & Shared Hosting

I've been trying to setup a webpage with MVC3 Razor, SQLCE 4 and Code First, the last two downloaded from Nuget, so it is EF Code First CTP5.

I've had a lot of trouble, but I manage to move forward by following this answer

However now I am getting this Security Exception

Description: The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file.

I thought it should work without full trust so I don't know what is wrong now.

I am using GoDaddy shared hosting with .Net 4 and IIS7

What could be the issue?

EDIT:

I haven't modified the web.config, except for setting custom errors = false to be able to see the exceptions, otherwise I have the webconfig that was generated by using Nuget to get and configure SQLCE and Code first

This is how it is:

It seems to be a bug with CTP5 that will be fixed in final release.

Hmmm as I said in the first comment on the question, it is an error with Code First CTP5, which uses full trust instead of medium trust. Source
