The latest Unity Application Block information can be found at the Unity Application Block site.

Unity uses dynamically generated methods to perform injection, and the .NET Framework security model imposes some security limitations that you should be aware of if you want to use Unity in applications that will run in less than full trust environments. The limitation when using the Unity Application Block in a partial trust environment is that you cannot register and use mappings using the RegisterType methods where the target class is internal (C#), Friend (Visual Basic .NET), private (C#), or Private (Visual Basic .NET).

For more information about security issues when using dynamically generated MSIL code, see Security Issues in Reflection Emit for .NET 3.5 and Security Issues in Reflection Emit for .NET 2.0.
