使用 Windows API 代码包时出现 COMException

Question

我从以下位置下载了适用于 Microsoft® .NE​​T Framework 的 Windows® API 代码包 http://code.msdn.microsoft.com/WindowsAPICodePack/Release/ProjectReleases.aspx?ReleaseId=3077

错误

在 VS 2008 上测试解决方案时，出现一行错误

 IKnownFolderManager knownFolderManager = (IKnownFolderManager)new KnownFolderManagerClass();
 knownFolderManager.GetFolderIds(out folders, out count);

详情如下，
