Essential .NET Libraries Every Developer Should Know
Dealing with JSON in .NET? Newtonsoft.Json (aka Json.NET) has got you covered.

Why, after 6 years, I'm over GraphQL
In my opinion, the single biggest issue with Newtonsoft.Json is https://github.com/JamesNK/Newtonsoft.Json/issues/862.
Sure, you can disable it, but the fact that it is opt-out to begin with - i.e. that by default the parser will try to creatively interpret any string it sees in JSON input and convert in a locale-specific manner that also quietly loses data - is, frankly, insane through and through. I've personally run into this issue many times in existing code - it usually happens when people first start using the library and just never run into any inputs that would trigger this behavior while testing. Then once that code is shipped, someone somewhere just happens to have the data that triggers it.
And if you look at the comments to that issue, there are numerous mentions from other GitHub repos due to bugs it caused for them, including some Microsoft projects.
The cherry on that cake was author's response indicating that he doesn't even understand why this design is problematic in the first place: "I like what it does, I have no plans to change it, and I would do it again if given the chance." I wouldn't trust any parser written with this kind of attitude.

Should you use Newtonsoft.Json or System.Text.Json in 2023?
This bug and many others related to time: https://github.com/JamesNK/Newtonsoft.Json/issues/862 And they will never get fixes, because the project is kind of dead. Edit: and actually, the creator claim to have made it like this on purpose, so I don't trust it anymore.

React developer to NET
Nuget is where you'll get 3rd party libraries (such as Newtonsoft.Json for JSON processing)
- what library do i need to include for this json deserializer? (or how do i find what libs i need to include in general?)
