Question

I’ve been trying to configure interception for Unity (I want to log to log4net before and after object method calls).

I’ve used this example:

http://www.codeproject.com/KB/architecture/UnityAOPNHibernate.aspx

and its similar to this answer:

Microsoft Unity – code to xml

but I get “Unrecognized element ‘extensionConfig’.” – on the line where it does GetSection(“unity”) below.

        IUnityContainer unityContainer = new UnityContainer();
        var configurationSection = 
          (UnityConfigurationSection)ConfigurationManager.GetSection("unity")

Please help

<sectionExtension type="Microsoft.Practices.Unity.InterceptionExtension.Configuration.InterceptionConfigurationExtension, Microsoft.Practices.Unity.Interception.Configuration"/>
