Problem with determining abi of native libraries after updating xamarin

I madea question a while ago and i still have the same problem and i didnt found any answers. I already tried deleting the references and downloading updated .dlls but the same error persists.

C:\Program Files\MSBuild\Xamarin\Android\Xamarin.Android.Common.targets(3,3): Error: Cannot determine abi of native library RestSharp.dll. (MenuDigital)

I really have no idea and it was everything working since i had to change the build action from EmbeddedNativeLibrary to AndroidNativeLibrary...

I need this to work so does anyone have any ideia?
