Hi there,
The issue DYNPROXY-ISSUE-80 was just created by Jose Cano Ruiz (ppcanodehuelva).
Key: DYNPROXY-ISSUE-80
Summary: DP2 cannot proxy ServiceModel.IChannel class. (Exception from
HRESULT: 0x8007000B)
Type: Bug
Importance: High
Description:
Therefore wcf client proxies cannot access its IContextChannel
interface, and the WcfFacility implementation creates proxies whose
IContextChannel interface cannot be accessed (important limitation of the
facility).
Unit test below:
------------------------------------------------------------------------------
namespace castle.tests.nunit.bug

using System;
using System.Collections.Generic;
using System.ServiceModel;
using System.ServiceModel.Channels;
using Castle.Core;
using Castle.Core.Interceptor;
using Castle.Windsor;
using Castle.DynamicProxy;
using NUnit.Framework;

System.ServiceModel.IContextChannel, therefore retrieved clients through
WcfFacility cannot access its IContextChannel")]
/// <summary>
