  NameDescription
Public propertyTypeIdWhen implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute.)
Public propertyValueGets the current LoaderOptimization value for this instance.

  NameDescription
Explicit interface implemetationPrivate method_Attribute.GetIDsOfNamesMaps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute.GetTypeInfoRetrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute.GetTypeInfoCountRetrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute.InvokeProvides access to properties and methods exposed by an object. (Inherited from Attribute.)

The LoaderOptimizationAttribute can only be set on the main method for an executable application and is ignored on all other methods.

The LoaderOptimizationAttribute attribute is specified with a LoaderOptimization enumeration value, which tells the loader what type of application to optimize for: SingleDomain, MultiDomain, or MultiDomainHost.

This attribute is only a hint to the loader and does not affect program behavior.

NoteNote

If custom code access security policy is set for the AppDomain, by using the SetAppDomainPolicy property, and the AppDomain is created using the MultiDomain flag, the effect is the same as specifying the MultiDomainHost flag; that is, only assemblies in the GAC are shared. When this occurs, the loader does not throw an exception and the application does not experience the performance gains associated with the MultiDomain flag.
