Sharing data between aspects in different assemblies during compile time

Question

I have a custom TypeLevelAspect called PersistentId which is used on types in several assemblies. I need to store information from these aspects during compile time and use it during runtime - but before the assemblies are loaded . Therefore, I was thinking about storing the information in another aspect - in a different assembly which would definitely be loaded.

Is it possible to somehow transfer data during CompileTimeInitialize of one aspect to a single instance of another aspect so that it can be stored and retrieved in RuntimeInitialize of the second aspect?

EDIT: Sharing data between aspects does seem to work (see the answer below) but only within a single assembly. Is there a mechanism to share it also between different assemblies?

Answer 1

The usual approach to share data between aspects using PostSharp Framework is (assuming you want to share a class MyData :

• Make sure the MyData class is serializable.
• Expose a static public field/property of type MyData somewhere.
• In all aspects that need MyData , expose an instance field of this type, and initialize it to the static instance.

At compile-time, PostSharp will serialize MyData in the aspect graph. Because this is a graph, a single instance of MyData will be shared among all aspect instances.
