MulticastAttributeUsageAttribute Class

There is no full equivalent of this attribute in Metalama, and there will not be. To mark an aspect as inherited, use the InheritableAttribute custom attribute. To specify the eligibility of an aspect, implement the BuildEligibility(IEligibilityBuilder<T>) method.

Constructors

Name	Description
MulticastAttributeUsageAttribute()
MulticastAttributeUsageAttribute(MulticastTargets)	In Metalama, the valid targets are determined by the declaration types for which the IAspect<T> interface is implemented. Additionally, you can implement the BuildEligibility(IEligibilityBuilder<T>) method.

Properties

Name	Description
AllowExternalAssemblies	Targeting external declarations is not supported in Metalama.
AllowMultiple	Metalama always allows multiple attributes, but only one is actually processed. The other instances are exposed in `builder`.AspectInstance.SecondaryInstances. It is up to the BuildAspect(IAspectBuilder<T>) implementation to handle the situation with many aspects.
Inheritance	To mark an aspect as inherited, use InheritableAttribute or implement IConditionallyInheritableAspect. Multicast inheritance is not supported in Metalama, but you can build a similar feature by making the aspect implement the IAspect<T> for INamedType and implement multicasting in the BuildAspect(IAspectBuilder<T>) method.
PersistMetaData	By default, custom attributes (metadata) are preserved in the code. To remove them, use the advice RemoveAttributes(IDeclaration, INamedType).
TargetExternalMemberAttributes	Applying an aspect to an external declaration is not supported in Metalama.
TargetExternalTypeAttributes	Applying an aspect to an external declaration is not supported in Metalama.
TargetMemberAttributes	In Metalama, implement the BuildEligibility(IEligibilityBuilder<T>) method.
TargetParameterAttributes	In Metalama, implement the BuildEligibility(IEligibilityBuilder<T>) method.
TargetTypeAttributes	In Metalama, implement the BuildEligibility(IEligibilityBuilder<T>) method.
ValidOn	In Metalama, the valid targets are determined by the declaration types for which the IAspect<T> interface is implemented. Additionally, you can implement the BuildEligibility(IEligibilityBuilder<T>) method.
