When I debug my android project this exception is thrown: "System.TypeLoadException: Could not resolve type with token 0100000f".
The last value for call stack is ">
0x21 in x.Droid.MainActivity.OnCreate at C:\Users\asus\Documents\Visual Studio 2015\Projects\x\x\x.Droid\MainActivity.cs:22,13 C#
".
Is there any code should I add to MainActivity.cs?

@smshafa Hi. Why do you think that this exception from Popup plugin?
Because when I've added the plugin, this exception has been thrown. I wanted to be sure about the problem and I copy the project and then remove the plugin and it works correctly. I set main page to a Master-detail page.
@smshafa My plugin can't throw this exception. Please, will try to create new project and will add into it my plugin. Exception will not be.
Running the project in Release Mode have no issues.
@smshafa because problem is not in Popup plugin
Running the android project in debug mode is also possible. This page helped me:
System.TypeLoadException: Could not resolve type with token
Thanks @rotorgames.
@smshafa Popup plugin supports all linked modes. Popup plugin use PreserveAttribute everywhere, It couldn't throw this error.
I did many tests for fixing linker problem.
@smshafa This is a general error with Xamarin, pops up seemingly randomly. You may or may not need to recreate your project to solve it, remove and reinstall nuget packages, etc. I had it once and I don't know what made it go away.聽Annoying, but not @rotorgames's fault
This issue was fixed in v1.1.0-pre1. Please test it and tell me about your tests. Thank you.
