If you are a .NET developer, you must have heard/used a nuget package called Newtonsoft.Json (or JSON.NET). The package is maintained by a legendary developer named James Newton-King.
Adding a permissive license to your open source projects makes it easy for others to benefit from reusing your code. I typically recommend the MIT license for most projects because it’s simple, well understood, and allows the code to be used for essentially any purpose.
