- .Net Standard 2.0 is not a breaking change from 1.6 but the doubling of the no. of APIs covered by the standard warranted the major version bump
- .Net Standard is implemented by .Net 4.6 and Xamarin and by .Net Core 2.0 etc.
- .NET Standard 2.0 standardizes the shared APIs across .NET Framework, .NET Core and Xamarin making it easy to share code across all of .NET. .NET Core gain over 5,000 APIs from .NET Framework as part of this work making it a broader platform.
