I have an ATL in-process server that implements a callback interface like so:

.idl

interface IClientEvents : IUnknown{
    [] HRESULT TestEvent(void);
};

interface IATLSimpleObject : IDispatch{

    [id(1)] HRESULT Advise([in] IClientEvents* clientEvents);
    [id(2)] HRESULT Unadvise(void);
};

.h

private:
    IClientEvents* m_ClientEvents;
public:
    STDMETHOD(Advise)(IClientEvents* clientEvents);
    STDMETHOD(Unadvise)(void);

.cpp

STDMETHODIMP CATLSimpleObject::Advise(IClientEvents* clientEvents)
{
    m_ClientEvents = clientEvents;
    m_ClientEvents->AddRef();

    return S_OK;
}

STDMETHODIMP CATLSimpleObject::Unadvise(void)
{
    m_ClientEvents->Release();
    m_ClientEvents = NULL;

    return S_OK;
}

C# client

public partial class Form1 : Form, ATLProject1Lib.IClientEvents
{
    private ATLProject1Lib.ATLSimpleObject ATLSimple = new ATLProject1Lib.ATLSimpleObject();

    private void Form1_Shown(object sender, EventArgs e)
    {
        ATLSimple.Advise(this);
    }

    private void Form1_FormClosing(object sender, FormClosingEventArgs e)
    {
        ATLSimple.Unadvise();
    }

It works fine, but I need to do exactly the same in an out-of-process server, however, on execution I get an 'Interface not Registered' (80040105) error when calling 'ATLSimple.Advise(this)'.

I've spent hours searching for similar problems, but can't find anything. Any help would be greatly appreciated.

为了使其在进程外工作，您需要在进程之间编组接口。您很可能希望依赖自动化编组，它使用从 IDL 生成的类型库来查找编组的内容和方式。问题在于，这仅适用于 IDL中标记为 的接口[oleautomation]，或两者兼有。有关更多详细信息，请参阅此答案。[dual]

你最好的办法是标记你想要编组的接口，[oleautomation]并添加一个评论，比如“如果你删除它，编组魔法就会消失”。
