It's a utility library. Creating utility libraries is hard, as no one will actually use them, because:

• No one wants a dependency on some rubbish utility library.
• It's exposing a lot of rubbish for external users, especially if you are using a utility library from another public library.

Therefore, this is IMHO a completely new approach:

• There is no library. In the traditional sense. No NuGet package. Just source code.
• In order to use this code, you reference single .cs file. As easy as that!
• Every single class in this codebase is private. Meaning it will be compiled into your codebase, but you can use it all, because it's private to your codebase.

This approach is very popular in other languages (C/C++, Golang, Rust) so why not trying it with .NET?

Good question! Installing it is pretty easy, just run in the folder you want it to be downloaded.

curl --location https://github.com/aloneguid/netbox/releases/download/x/NetBox.cs --output NetBox.cs

where x is the release number, like 4.0.2 (get the version you need from releases). This is also how you update it as well. Simple! Just put it in your build script or elsewhere, or just commit the .cs file locally, you know what to do!

To contribute, either add a method in a relevant class (tests are required!) or add a new file with corresponding tests. Run the tests as usual. Then raise a PR as usual.

Build pipeline will run the tests, create a single .cs file and push a new release.
