2. One library to rule them all
12/29/2017 2:33 PM
.NET Standard library
One library to rule them all
Learn one API across ALL .NET platforms
Reuse your code across ALL .NET platforms
Easily consume third-party/OSS libraries across ALL .NET platforms
.NET Standard 1.x
Evolution of Portable Class Libraries (PCLs) with a much simpler model
Two constraints:
API surface relatively small, because .NET Core was small
Can’t reference the vast number of libraries already available for .NET Framework

+20K
More APIs than
.NET Standard 1.x
Has much bigger API surface
Extended to cover intersection between .NET Framework and Xamarin
Also makes .NET Core 2.0 bigger as it implements .NET Standard 2.0
~70%
of NuGet packages
are API compatible
Can reference .NET Framework libraries
Compatibility shim allows referencing existing .NET Framework binaries
No recompile required – also covers existing NuGet packages
Limited to libraries that only use APIs that are available for .NET Standard
