Running OpenBehavior before IRequestPreProcessor

[japhettburt-bam]

I am using 12.2.0. I am trying to get an OpenBehavior to run before the IRequestPreProcessor runs for a particular IRequest. I am not sure what I am missing since I am trying to register them in explicit order.

services.AddMediatR(cfg =>
{
    cfg.RegisterServicesFromAssemblies(assemblies);
    cfg.AddOpenBehavior(typeof(SensitiveDataBehavior<,>));
    assemblies
        .SelectMany(a => a.GetTypes())
        .Where(p =>
            p.GetInterfaces().Any(i => i.Name == typeof(IRequestPreProcessor<>).Name)
        )
        .ToList()
        .ForEach(t => cfg.AddRequestPreProcessor(t));
    cfg.AddOpenBehavior(typeof(TransactionBehavior<,>));
});

The TransactionBehavior runs after the IRequestPreProcessor just how I want but the SensistiveDataBehavior is not running before the IRequestPreProcessor. Is there a way to make this happen?

I was re-reading the handler/action priority order part of the wiki and if I am reading this correctly this might be my issue?

• IRequestPreProcessor is in the same namespace i.e. commands.class.UpdateClass which is next to the handler
• SensitiveDataBehavior is in the namespace infrastructure which is alongside commands.

Edit: I just tried moving the SensitiveDataBehavior into the same folder as everything and updated the namespace and didn't seem to have an impact so I am still confused.
