在VS 2012调用CoCreateInstance的过程中符号的加载速度慢(Slow loadin

在我的MFC项目我叫CoCreateInstance一些观点：

if ( SUCCEEDED( CoCreateInstance ( CLSID_DragDropHelper, NULL,
                                   CLSCTX_INPROC_SERVER,
                                   IID_IDropTargetHelper,
                                  (void**) &m_piDropHelper ) ))
{
   ...
}

和稍后一旦我用做DragDropHelper我打电话Release ：

m_piDropHelper->Release();

到目前为止好，一切工作正常。

但在调试这个最先调用CoCreateInstance是痛苦的缓慢，因为VS加载吨的符号（此负荷在VS输出窗口中看到，见下文）。相同的后续调用CoCreateInstance快。但是，当我重新去调试者，这在第一次调用CoCreateInstance缓慢一次。

我不需要这些符号我的目的。

有没有一种方法，以防止Visual Studio中加载所有这些符号。
