I have developed the following. Seems to work. I am still having issues
under heavy load, but I think it¹s something else.
If it looks okay, I will submit a patch. I was thinking I might also add a
config option ³isWcf².
public class WcfThreadScopeInfo : AbstractThreadScopeInfo
{
public override Stack CurrentStack
{
[MethodImpl(MethodImplOptions.Synchronized)]
get
{
var current = OperationContext.Current;
if (current == null)
{
var message = "WcfThreadScopeInfo: Could not access
OperationContext.Current";
throw new ScopeMachineryException(message);
}
var extension = current.Extensions.Find<StackExtension>();
if (extension == null)
{
extension = new StackExtension();
OperationContext.Current.Extensions.Add(extension);
}
if (extension.Stack == null)
{
extension.Stack = new Stack();
}
return extension.Stack;
}
}
private class StackExtension : IExtension<OperationContext>
{
public Stack Stack { get; set; }
public void Attach(OperationContext owner) { }
public void Detach(OperationContext owner) { }
}
}

The app uses Rhino.Commons and its Repository<T>, underlying which is
NHibernate. I use ActiveRecord attributes for mapping only. The
application is a Rhino.Commons' UnitOfWorkApplication.
My service classes are decorated with [Transactional] and the methods with
[Transaction].
I know you are not a Rhino Commons expert and so this might not be enough
detail, and maybe it's some Rhino Commons issue?
