- Utilized Microsoft.CodeAnalysis.CSharp.SourceGenerators.Testing to improve the quality of the Generator tests.

## Fixed

- The generated code files for classes now apply a conditional preprocessor directive to #nullable calls to prevent compilation failure in .NET Standard 2.0 projects.
- The generated extensions no longer call ArgumentNullException.ThrowIfNull to prevent compilation failure in .NET Standard 2.0 projects.
- The generated extensions no longer use pattern matching to prevent compilation failure in .NET Standard 2.0 projects.
- The generated constructor for records now applies a preprocessor directive to the SetRequiredMembers attribute to prevent compilation failure in .NET 6 projects (#5).
