New Security Model: Moving to a Better Sandbox
New Security Model: Moving to a Better Sandbox
 For .Net Framework 4, we decided to remove the dependency on caspol and the policy levels and make things simpler. With this change, the default grant-set for assemblies is now FullTrust unless the host (such as InternetExplorer) decides to load them in a sanbox. We also made CodeAccessPermission.Deny obsolete.

One of the new features in CLR 4 is In-Process Side-by-side (Inproc SxS) – a feature that lets you use multiple versions of .NET in the same process.
