XAMARIN ANDROID app got System.ServiceModel.FaultException

I have an app running well, but after I upgrade visual studio 2019 OSX, I got the exception when running the app.

Target _ResolveSatellitePaths: 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".

I knew it's a dll conflict issue. but I can't find a way to fix it. thanks for any information.

Have a try with updating DeepCloner to the latest verson 0.10.2to check whether solve this .

In this release we're removed System.Reflection namespace from cloning, because some classes in System.Reflection.Emit cause unexpected crashes in runtime. Also, there are no significant reasons to clone these classes.

Also, checking for empty constructors is improved to reduce number of exceptions (internally catched, but can slow down copying).
