Override base class aspect in derived class

I have a generic repository class with various methods marked with a PostSharp aspect (SecuredOperation)...

public class Repository<TEntity> : IRepository<TEntity>, ISecurable
    where TEntity : class, IEntity

    public virtual void Add(TEntity entity)


In some of my derived repository classes I want to change the required access on the Add() method (e.g. DomainAccess.None).

My initial attempt was to override the method and reapply the aspect...

public class SomeRepository : Repository<SomeEntity>

    public override void Add(SomeEntity entity)


The aspect is correctly applied to this overridden method, however once I call the base class implementation the base class aspect kicks in.

Obviously duplicating the base class logic in the derived classes is not a solution.

How can I get around this problem of overriding a base class aspect in a derived class?

    This behavior is by design and is ok for most situations.
    In your case, I suggest you use a ThreadStatic constructs to store the information whether a access verifications should be ignored. The precise type of your ThreadStatic field depends on the level of complexity of your security requirements.
