VS2019升级到16.6问题特多,问题也比较奇葩!在部署调试到模拟器出现:Xamarin.Android does not support running the previous version.  Please ensure your solution builds before running or debugging it.

前天使用最新版的Xamarin Forms 4.4提交应用后,今天Apple审核返回信息如下:
Guideline 2.5.1 – Performance – Software Requirements

Your app uses or references the following non-public APIs:
– LinkPresentation.framework
– QuickLookThumbnailing.framework
The use of non-public APIs is not permitted on the App Store because it can lead to a poor user experience should these APIs change.
Continuing to use or conceal non-public APIs in future submissions of this app may result in the termination of your Apple Developer account, as well as removal of all associated apps from the App Store.
Next Steps
If you are using third-party libraries, please update to the most recent version of those libraries. If you do not have access to the libraries’ source, you may be able to search the compiled binary using the “strings” or “otool” command line tools. The “strings” tool can output a list of the methods that the library calls and “otool -ov” will output the Objective-C class structures and their defined methods. These tools can help you narrow down where the problematic code resides. You could also use the “nm” tool to verify if any third-party libraries are calling these APIs.
