Unity 1.2 and PIAB: Creating a Unity Extension that auto configures the container with PIAB policies
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?
