Visual Studio 2017 为我的多平台 xamarin 应用程序报告此错误

Question

Someone Help I have been on this issue for 4 days, my app was working perfectly fine when it started reporting this error "This debug engine does not support exception conditions. The condition(s) will be ignored". It does not find some of the dll.so packages, I tried deleting the bin and debug folder, and rebuild the App, I have also reinstalled and installed visual studio, formatted my PC and did a clean installation all to no avail. The same comes up, when I try running the same app from different user in the project Repo in gitlab. I tried different emulators and now using my phone but still mp solution.

 This debug engine does not support exception conditions. The condition(s) will be ignored. 03-04 23:59:08.480 E/Zygote (32704): v2 03-04 23:59:08.480 I/SELinux (32704): Function: selinux_compare_spd_ram, index[1], SPD-policy is existed.

Answer 1

In my case the problem went away after closing Visual Studio, deleting the obj and build folders, and then building again. Using the clean and rebuild options in Visual Studio didn't work, so it seems Xamarin in Visual Studio doesn't do a proper clean/rebuild.

This was a major waste of time since it started with breakpoints just not being hit when I expected them to without knowing why. The message This debug engine does not support exception conditions. The condition(s) will be ignored. This debug engine does not support exception conditions. The condition(s) will be ignored. is very easy to miss because there is a lot of noise in the log during startup.
