A source code only package which allows you to use .NET Core 3.0's new nullable attributes in older target frameworks like .NET Standard 2.0 or the "old" .NET Framework.

This package does not contain any compiled binaries, but instead adds a single C# file with the attribute classes to your project. Because this C# file gets compiled together with the rest of your code, the built binaries will not have a dependency on this package, meaning that you can perfectly use this package for both libraries and applications.

Please see for additional information on how to use this package.
