推荐答案

首先，如果您要发布图片链接，请确保可以轻松阅读文本.
或者，也可以根据喜好复制并粘贴文本...

您已降低了要定位的Framework的版本.这意味着您添加的所有控件或引用也必须使用较低的版本-否则在将应用发布到生产环境时它们将失败.错误告诉您，至少其中一个需要更高的版本-但是文本非常不清楚，我无法弄清哪个版本.

First, if you are going to post a link to a picture - MAKE SURE THAT THE TEXT CAN BE READ EASILY.
Or, by preference, copy and paste the text instead...

You have lowered the version of the Framework you are targeting. That means that any controls or references that you have added must also use the lower version - or they will fail when the app is released to production. The error is telling you that at least one of them needs a higher version - but the text is so unclear I can''t work out which.

Clean Ur旧参考并添加新参考并重新编译您的项目就可以了

Clean Ur Old reference and add new reference and reCompile ur project it will be ok
