I am converting my .Net 4.5 class library to .Net Standard Library 1.2 (as we want to support Cross platform.
Few of my classes and interfaces use attributes ContractClassFor and ContractClass. These classes belongs to System.Diagnostics.Contracts. But I can not find thess classes in XAMARIN.
What are the equivalent classes for those I can use? Or if no classes present, how can I replace the code with ?
Thanks so much
