Is there any way to disable Method and Property injection and Interception features? I want to measure if it influence speed of object graph creation.

Unity Interception is implemented as a UnityContainerExtension and it is not added by default (all of the logic is in a separate assembly).

I'm not sure if you can 100% remove method and property injection (I wasn't able to do it but perhaps someone else has?).  I was able to swap out the default implementation with another so that the overhead would be minimal:

    class Program
    {
        static void Main(string[] args)
        {
            UnityContainer container = new UnityContainer();
            container.AddNewExtension<RemoveContainerExtension>();

            var x = container.Resolve<MyClass>();
        }
    }

    public class RemoveContainerExtension : UnityContainerExtension
    {
        protected override void Initialize()
        {
            Context.Policies.SetDefault<IPropertySelectorPolicy>(new MyPropertySelector());
            Context.Policies.SetDefault<IMethodSelectorPolicy>(new MyMethodSelector());
        }

        public class MyMethodSelector : IMethodSelectorPolicy
        {
            public IEnumerable<SelectedMethod> SelectMethods(IBuilderContext context, IPolicyList resolverPolicyDestination)
            {
                return Enumerable.Empty<SelectedMethod>();
            }
        }

        public class MyPropertySelector : IPropertySelectorPolicy
        {
            public IEnumerable<SelectedProperty> SelectProperties(IBuilderContext context, IPolicyList resolverPolicyDestination)
            {
                return Enumerable.Empty<SelectedProperty>();
            }
        }
    }

Another approach would be to download and modify the source code to do exactly what you want.

Thanks. I will try on our project and see what results regarding application start up time are.

Hi,

related to the previous question.  In my project we are using the unity interception but in one of the scenario i don't want to execute the interception call.  That means based on the config switch i want to disable the specific interception call.

HandlerAttribute has the createhandler method with return type of iCallHandler.  is there any way that i can return a dummy call hander when my switch says off the callhandler.

I would recommend starting a new discussion with your specific scenario.  You can use matching rules in configuration to enable/disable interception.
