What replaced HttpOperationHandler in WCF Web API to ASP.NET Web API

Question

In upgrading an old project that was built using WCF Web API to now use ASP.NET Web API, I have run into a few classes that implement HttpOperationHandler<HttpRequestMessage, T>. I'm unable to find an equivalent class in the new assemblies. Does something similar exist or will I need a different approach?

Answer 1

The concept of Operation handlers has been replaced with Filters and model binders.

Here are some links that you might find useful:
