Several months ago, Microsoft decided to change up the HttpResponseMessage class. Before, you could simply pass a data type into the constructor, and then return the message with that data, but not anymore.
Now, you need to use the Content property to set the content of the message. The problem is that it is of type HttpContent, and I can't seem to find a way to convert a string, for example, to HttpContent.
Does anyone know how to deal with this issue? Thanks a lot.

IHttpActionResult contains a single method, ExecuteAsync, which asynchronously creates an HttpResponseMessage instance. If a controller action returns an IHttpActionResult, Web API calls the ExecuteAsync method to create an HttpResponseMessage. Then it converts the HttpResponseMessage into an HTTP response message.
A HttpResponseMessage allows us to work with the HTTP protocol (for example, with the headers property) and unifies our return type. In simple words an HttpResponseMessage is a way of returning a message/data from your action.
CreateResponse<T>(HttpRequestMessage, HttpStatusCode, T) Helper method that performs content negotiation and creates a HttpResponseMessage with an instance of System.
For a string specifically, the quickest way is to use the StringContent constructor
response.Content = new StringContent("Your response text"); There are a number of additional HttpContent class descendants for other common scenarios.
