Not applicable.



The friendly name of the domain. This friendly name can be displayed in user interfaces to identify the domain. For more information, see the description of FriendlyName.


Evidence mapped through the security policy to establish a top-of-stack permission set. Pass a null reference (Nothing in Visual Basic) to use the evidence of the current application domain.


An object that contains application domain initialization information.


A default permission set that is granted to all assemblies loaded into the new application domain that do not have specific grants.


An array of strong names representing assemblies to be considered fully trusted in the new application domain.

Return Value

The newly created application domain.

Exception typeCondition


friendlyName is a null reference (Nothing in Visual Basic).


The application domain is a null reference (Nothing in Visual Basic).

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 a null reference (Nothing in Visual Basic) 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.
