Repository that defines a lot of small back-port packages of attributes and other system types that became available somewhen along the time-line of .NET and which are well-used by compiler and programmers alike but do not work in older frameworks.
These packages allow to use these features also in older frameworks (make sure to add <LangVersion>Latest</LangVersion> to your project).
It is recommended not to reference these packages directly but use package Hafner.Compatibility.MetaPackage instead.
