autofac wcf客户端配置

// Step 2: Create a custom instance context provider
public class CustomInstanceContextProvider : DefaultInstanceContextProvider
{
    protected override InstanceContext GetExistingInstanceContext(Message message, IContextChannel channel)
    {
        // Custom logic to get or create the instance context
        // ...
    }
}

// Step 3: Create a custom channel factory provider
public class CustomChannelFactoryProvider : DefaultChannelFactoryProvider
{
    protected override ChannelFactory<TChannel> GetChannelFactory<TChannel>(Type clientType, Binding binding)
    {
        // Custom logic to create the channel factory
        // ...
    }
}

// Step 4: Configure Autofac for WCF client
var builder = new ContainerBuilder();

// Register WCF service implementation
builder.RegisterType<MyService>().As<IMyService>().InstancePerLifetimeScope();

// Step 5: Register WCF client
builder.RegisterWcfClient<IMyService>(client => client
    .ConfigureChannelFactory(cf => cf.ForEndpoint("MyServiceEndpoint"))
    .UseInstanceContextMode(InstanceContextMode.Single)
    .UseInstanceContextProvider<CustomInstanceContextProvider>()
    .UseChannelFactoryProvider<CustomChannelFactoryProvider>()
).InstancePerLifetimeScope();

// Build the container
var container = builder.Build();
