Following my last post around Unity and PIAB, and as already mentioned, PIAB policies have to be explicitly applied to a Unity Container.

But what about if you want to apply always the PIAB policies to your container? Easy, apply an extension that does that for you:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Microsoft.Practices.EnterpriseLibrary.Common.Configuration;
using Microsoft.Practices.EnterpriseLibrary.PolicyInjection.Configuration;

namespace MyExtensions
{
    public class PolicyInjectionInterceptionExtension: Microsoft.Practices.Unity.InterceptionExtension.Interception
    {
        protected override void Initialize()
        {
            base.Initialize();

            // Get the PIAB config out of entlib config
            var configSource = ConfigurationSourceFactory.Create();
            var section = (PolicyInjectionSettings)configSource.GetSection(PolicyInjectionSettings.SectionName);
            // Apply PIAB settings, if any, to the container
            if (section != null)
            {
                section.ConfigureContainer(this.Container, configSource);
            }

        }

    }
}

So, instead of adding the standard Microsoft.Practices.Unity.InterceptionExtension.Interception extension, you can add MyExtensions.PolicyInjectionInterceptionExtension which auto configures the container for you.

Pretty easy, right?
