Visual Studio 菜单项出现多次

Question

我已经为我正在开发的扩展程序创建了一个菜单项；然而，它在“工具”菜单中出现了 4 次而不是一次。以下是我所拥有的，但我一直无法弄清楚为什么菜单项出现不止一次。

我似乎无法弄清楚我可能做错了什么。有什么建议吗？

...what I might be doing wrong.

您实际上是在尝试将两个包 (TemplatePackPackage 和 MenuOptionsPackage) 捆绑到一个包中，这会弄乱您的 .pkgdef 文件，我认为这是你的问题。

如果您注释掉 MenuOptionsPackage class，那么您应该只会看到一个菜单项 - 正如预期的那样。

Any suggestions?

通过单个 Package class.
创建两个不同的扩展项目，每个项目包含相应的 Package。如果您需要通过另一个访问一个，您可以 provide and consume 服务。
