Creates a new application domain with the given name, using evidence, application base path, relative search path, and a parameter that specifies whether a shadow copy of an assembly is to be loaded into the application domain. Specifies a callback method that is invoked when the application domain is initialized, and an array of string arguments to pass the callback method.

Namespace: System

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 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.


The base directory that the assembly resolver uses to probe for assemblies. For more information, see BaseDirectory.


The path relative to the base directory where the assembly resolver should probe for private assemblies. For more information, see RelativeSearchPath.


true to load a shadow copy of an assembly into the application domain. For more information, see ShadowCopyFiles and Shadow Copying Assemblies.


An AppDomainInitializer delegate that represents a callback method to invoke when the new AppDomain object is initialized.


An array of string arguments to be passed to the callback represented by adInit, when the new AppDomain object is initialized.

Return Value

The newly created application domain.

Exception typeCondition


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

The method represented by adInit is executed in the context of the newly created application domain.

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

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.
