A .Net library to handle conversions from and to JSON (JavaScript Object Notation) strings.

It's quick and lean, without external dependencies. Just a few classes so easily embeddable in your own code or a very small assembly to ship with your code. The code is highly portable, which in general makes it easy to adapt for new platforms.

Code can be compiled using .NET CLI or by launching the bootstrappers in the root of the repository.



Linux / OS X



The bootstrappers will (locally in repo)

  • Fetch and install .NET Core CLI / SDK version needed to compile LitJSON.
  • Fetch and install Cake runner
  • Execute build script with supplied target (--target=[Target]) or by default
    1. Clean previous artifacts
    2. Restore build dependencies from NuGet
    3. Build
    4. Run unit tests
    5. Create NuGet package


This library comes with a set of unit tests using the NUnit framework.

Using LitJSON from an application

Package manager
