 # TLDR? What is this for? ✨
 
-Put simply: are you working on .NET Framework, or UWP, or some other older .NET runtime and still would like to use all the cool new features that C# 13 has? Well this library lets you do just that! It will generate for you all the "magic types" that the C# compiler needs to "see" in order for it to allow using new language features even if you're not using the latest framework out there.

For instance, by adding `<LangVersion>13.0</LangVersion>` (or your desired C# version) to the first `<PropertyGroup>` of your .csproj file.
