Usage of AspectPriority

Question

I'm using PostSharp 2.1.5.1 and had a warning today:

Aspect dependencies (defined on "MyNamespace.MyAspect.MyVerificationAttribute") will be disabled from the Starter Edition in future versions. Use the AspectPriority property instead.

Seems to me that following line is causing that warning:

[AspectRoleDependency(AspectDependencyAction.Order, AspectDependencyPosition.After, StandardRoles.Tracing)]

Could someone point me to a correct example of how to use AspectPriority? Are the following examples up to date?

• http://www.sharpcrafters.com/blog/post/introducing-postsharp-2-0-3-aspect-dependencies.aspx (section "Old Good Aspect Priority")

• http://www.sharpcrafters.com/blog/post/Day-3-Applying-Aspects-with-Multicasting-Part-2.aspx (section "Aspect Priority")

Thanks.

The correct usage is AttributePriority. Lower values are higher priority, or aspects that get applied first.

[Trace(AttributePriority = 2)]
[HandleError(AttributePriority = 1)]
public void MyMethod()
{

}

Aspect Priority hasn't been valid for a while. AspectDependencyAction determines the "priority" between two aspects. Meaning, if Aspect1 depends on Aspect2 then and the AspectDependencyAction.Order = After then Aspect1 gets applied after Aspect2 has been applied. but that isn't what you are looking for (I think). Just use AttributePriority instead.
