The newly created application domain.


friendlyName is null.


The application domain is null.

If securityInfo is not supplied, the evidence from the current application domain is used.

The information provided for grantSet and fullTrustAssemblies is used to create an ApplicationTrust object for the new application domain.

If the current application domain has an empty Evidence, SecurityException is thrown when creating a new application domain and passing null for securityInfo. An empty Evidence always results in an empty grant set. For example, a default application domain can have an empty Evidence if it is created from unmanaged code.
