这种大版本升级基本没有考虑兼容性的做法，对此感到很难受。
包括VS2022应用扩展也是一直没有更新，对应生成的.net 4.x 的nuget包直接在新的uipath里面无法识别，真是糟糕。
Are you using windows projects or legacy projects and also what studio version you are using if you have built custom library in legacy then it won’t support in windows you need to rebuild in windows
in which compatibility is library built?
project also needs to be in same compatibility
cheers
