Constructors
NameDescription
System_CAPS_pubmethod LoaderOptimizationAttribute

Initializes a new instance of the LoaderOptimizationAttribute class to the specified value.

System_CAPS_pubmethod LoaderOptimizationAttribute

Initializes a new instance of the LoaderOptimizationAttribute class to the specified value.

Properties
NameDescription
System_CAPS_pubproperty

When implemented in a derived class, gets a unique identifier for this Attribute.(Inherited from Attribute.)

System_CAPS_pubproperty

Gets the current LoaderOptimization value for this instance.

Methods
NameDescription
System_CAPS_pubmethod Equals

This API supports the product infrastructure and is not intended to be used directly from your code. Returns a value that indicates whether this instance is equal to a specified object.(Inherited from Attribute.)

System_CAPS_pubmethod GetHashCode

Returns the hash code for this instance.(Inherited from Attribute.)

System_CAPS_pubmethod GetType

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_pubmethod IsDefaultAttribute

When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.(Inherited from Attribute.)

System_CAPS_pubmethod Match

When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.(Inherited from Attribute.)

System_CAPS_pubmethod ToString

Returns a string that represents the current object.(Inherited from Object.)

Explicit Interface Implementations
NameDescription
System_CAPS_pubinterface System_CAPS_privmethod _AttributeGetIDsOfNames

Maps a set of names to a corresponding set of dispatch identifiers.(Inherited from Attribute.)

System_CAPS_pubinterface System_CAPS_privmethod _AttributeGetTypeInfo

Retrieves the type information for an object, which can be used to get the type information for an interface.(Inherited from Attribute.)

System_CAPS_pubinterface System_CAPS_privmethod _AttributeGetTypeInfoCount

Retrieves the number of type information interfaces that an object provides (either 0 or 1).(Inherited from Attribute.)

System_CAPS_pubinterface System_CAPS_privmethod _AttributeInvoke

Provides access to properties and methods exposed by an object.(Inherited from Attribute.)

Remarks

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.

System_CAPS_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.
