 JsonApiDotnetCore provides a framework for building [json:api](http://jsonapi.org/) compliant web servers. Unlike other .Net implementations, this library provides all the required middleware to build a complete server. All you need to focus on is defining the resources. However, the library is also fully extensible so you can customize the implementation to meet your specific needs.
