Question

I’m trying to implement an OnMethodBoundary aspect on an abstract method in an abstract class so that all types that inherit from this class will automatically have the aspect applied. There are no compilation errors or warnings, but the OnEntry method doesn’t fire. Note: If I apply the aspect to a non-abstract method, everything works fine

here’s the aspect example:

---

    [Serializable]
    [MulticastAttributeUsage(MulticastTargets.Method, Inheritance = MulticastInheritance.Multicast)]
    public sealed class DoSomethingAttribute : OnMethodBoundaryAspect
    {
        public override void OnEntry(MethodExecutionArgs args)
        {
            //Do work
        }
    }

// here’s the abstract class

public abstract class Job
    {
        //...
        [DoSomething]
        public abstract void Run();
    }

Updated answer: it doesn’t matter where anything is, as long as both projects have Postsharp referenced then you’re good to go.

It works just fine. Which version of PostSharp are you using?

class Program
{
    static void Main(string[] args)
    {
        Job1 j = new Job1();
        j.Run();
        Console.ReadKey();
    }
}

[Serializable]
[MulticastAttributeUsage(MulticastTargets.Method, Inheritance = MulticastInheritance.Multicast)]
public sealed class DoSomethingAttribute : OnMethodBoundaryAspect
{
    public override void OnEntry(MethodExecutionArgs args)
    {
        Console.WriteLine("OnEntry");
    }
}

public abstract class Job
{
    //...
    [DoSomething]
    public abstract void Run();
}

public class Job1 : Job
{

    public override void Run()
    {
        Console.WriteLine("Run method");
    }
}

Results:

OnEntry 
Run method
