推荐答案

您可能无法导出课程。请参阅 http://msdn.microsoft.com/en-us/library/81h27t8c .aspx

You're probably not exporting your class. See here http://msdn.microsoft.com/en-us/library/81h27t8c.aspx

此外，检查这种问题的一个不错的工具是depends.exe，包括在Visual Studio中，它允许您检查导出和导入的符号。

Also, a nice tool to check for this kind of issues is depends.exe, included with Visual Studio, which allows you to check for exported and imported symbols.
