Xamarin无法通过以下方式将应用程序部署到仿真器:“意外的安装输出:cmd:找不到服务:程序包"

I'm building the sample intro xamarin forms app With Visual studio 2019 and the emulator boots up but the app doesn't deploy with the error Unexpected install output: cmd: Can't find service: package":1>No way to resolve conflict between "mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" and "mscorlib, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e".
