Question

我在调用使用MAF（System.AddIn）托管的插件时，在某些计算机上不时有AppDomainUnloadedExcpetion。这就是我的管道：

[AddInContract] 
public interface IGatewayV2 : IContract
{
     ITopUpResultContract TopUpPhoneAccount(ITopUpRequestContract request);
}

这是我的主机适配器：

[HostAdapterAttribute()]
public class GatewayContractToViewHostSideAdapter : Dogs.Pipeline.HostView.IGatewayV2
{
    private Dogs.Pipeline.Contracts.IGatewayV2 _contract;
    private ContractHandle _handle;

    public GatewayContractToViewHostSideAdapter(Dogs.Pipeline.Contracts.IGatewayV2 contract)
    {
        _contract = contract;
        _handle = new ContractHandle(contract);
    }

    public TopUpResult TopUpPhoneAccount(TopUpRequest request)
    {
        var topupRequestViewToContractHostSideAdapter = new TopUpRequestViewToContractHostSideAdapter(request);

        return
            new TopUpResultContractToViewHostSideAdapter(
                _contract.TopUpPhoneAccount(topupRequestViewToContractHostSideAdapter));

    }
}

总是在主机适配器端我有一个topupRequestViewToContractHostSideAdapter：

class TopUpRequestViewToContractHostSideAdapter : ContractBase, ITopUpRequestContract
{
    private TopUpRequest _topUpRequest;

    public TopUpRequestViewToContractHostSideAdapter(TopUpRequest topUpRequest)
    {
        this._topUpRequest = topUpRequest;
    }

    //properties here
)

和TopUpResultContractToViewHostSideAdapter处理对外部appdomain的引用：

  public class TopUpResultContractToViewHostSideAdapter : TopUpResult
  {
    private ITopUpResultContract _contract;
    private ContractHandle _handle;

    public TopUpResultContractToViewHostSideAdapter(ITopUpResultContract contract)
    {
        this._contract = contract;
        _handle = new ContractHandle(contract);
    }

    //properties here
  }

在插件方面，我有以下代码：

[AddInAdapter()]
public class GatewayViewToContractAddInSideAdapter : ContractBase, Dogs.Pipeline.Contracts.IGatewayV2
{
    private Dogs.Pipeline.AddinViewV2.IGatewayV2 _view;

    public GatewayViewToContractAddInSideAdapter(Dogs.Pipeline.AddinViewV2.IGatewayV2 view)
    {
        this._view = view;
    }

    public ITopUpResultContract TopUpPhoneAccount(ITopUpRequestContract request)
    {
        var result = _view.TopUpPhoneAccount(new TopUpRequestContractToViewAdapter(request));
        return new TopUpResultViewToContractAdapter(result);
    }
}

TopUpResultViewToContractAdapter是：

public class TopUpResultViewToContractAdapter : ContractBase, ITopUpResultContract
{ 
    private TopUpResult _topUpResult;

    public TopUpResultViewToContractAdapter(TopUpResult result)
    {
        this._topUpResult = result;
    }

    //properties here
}

并且TopUpRequestContractToViewAdapter是：

public class TopUpRequestContractToViewAdapter : TopUpRequest
{
    private ITopUpRequestContract _contract;
    private ContractHandle _handle;

    public TopUpRequestContractToViewAdapter(ITopUpRequestContract contract)
    {
        _contract = contract;
        _handle = new ContractHandle(contract);
    }

    //properties here
}

所有内容似乎都符合我目前所阅读的内容，尤其是我在此链接中可以阅读的内容：http://msdn.microsoft.com/en-us/library/bb384186(v=vs.100).aspx 所以我想知道我是做错了什么，或者管道在某些机器上不起作用的可能性（因为我在所有机器上都没有问题我和＃39 ; m用于测试）。

感谢任何提示。

使用MAF的AppDomainUnloadedException（Microsoft Addin Framework）
