Hello,
I was trying Visual Studio 2015 CTP and got ASP.NET 4.6 upgrade during the
VS installation. I use Windsor WCF integration, which seems to get broken
due to this upgrade. I'm
injecting Castle.Facilities.WcfIntegration.IWcfClientFactory to my services
and use this simple extension method to retrieve the WCF client:
public static T GetClient<T>(this IWcfClientFactory factory) where
T : class
{
var componentName = typeof (T).FullName;
return factory.GetClient<T>(componentName);
}
The GetClient method throws this exception after the upgrade:
Castle.MicroKernel.ComponentActivator.ComponentActivatorException:
WcfClientActivator: could not proxy component XXX ---> System.
NullReferenceException: Object reference not set to an instance of an object
.

There's obviously some breaking change in ASP.NET 4.6 WCF. I already tried
to debug the Windsor source code, bud wasn't able to understand the code
enough to be able to figure out where the problem is. Did anyone faced the
same problem? Any hints what to try to workaround the problem?
