Xamarin Auth Account Store

I had been using Xamarin.Auth to save the password locally. After upgrading Xamarin.Auth 1.6.0.2 I can see that AccountStore.Create() method is now obsolete. It suggests to change the signature to AccountStore.Create(Android.Content.Context,String). as the previous method had security concerns.
In my shared project , I changed the definition to AccountStore.Create(Constants.AccountStorePassword), but it gives build error.
Saying "No Overload Method for 'Create' takes one argument".
Can anyone please suggest me what changes do I have to make?
or Do I have to implement the methods natively?
