In the past, a bunch of us from the ASP.NET Web API community worked together on a WebApiContrib project (or really, projects, cause there were many of them!).
The idea was to provide an easy to use platform, a one stop place for community contributions for ASP.NET Web API – both larger add ons, such as HTML/Razor support for Web API, as well as smaller things like i.e. reusable filters or even helper methods. This worked extremely well – WebApiContrib packages were downloaded over 500k times on Nuget, and a nice community has emerged around the project on Github.
Recently, we decided to restart the project, this time focusing on ASP.NET Core. Since the “brand” has caught on in the community and is fairly recognizable, we just called it WebApiContrib.Core.
