这是基于以下提问者的自我解答，而不是问题.

如果您删除项目/模块，则输出DLL/XAP文件会在周围徘徊.如果单击显示所有文件"按钮，您将在以下目录的 clientbin ， bin 和 obj 文件夹中看到一些剩余的输出文件.相关项目.

If you delete a project/module the output DLLs/XAP files do hang around. If you click the "show all files" button you will see some these left-over output files in your clientbin, bin and obj folders of related projects.

您可以从项目中单独删除它们，或者在有疑问时，搜索所有BIN和OBJ(例如，使用桌面资源管理器)并删除所有这些文件夹.必要时将重新创建BIN/CLIENTBIN/OBJ文件夹(这是Visual Studio中干净"选项应该完成的工作！)

You can delete them individually from the project, or, when in doubt, search for all BIN and OBJ (e.g. using desktop explorer) and delete all those folders. The BIN/CLIENTBIN/OBJ folders will be recreated when needed (this the job that the "clean" option in Visual Studio should have done!)

希望这会有所帮助.
