Could not load assembly java.interop in xamarin

I am tired of getting this error frequently. After installing "Xamarin.Forms.Maps" from nuget, getting this error message : "could not load assembly java.interop".

After searching for quite a while, I found a solution. There should be "java.interop.dll" in "C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\MonoAndroid\v1.0" - this directory. If the dll was there, I could have referenced it manually. But unfortunately, there is not any dll named like this in my machine. In this case, please give me any solution for this.

Thanks in advance.
