The third line shows the current time with date (this information is useful when we want to log the HTTP request time) then the last two lines show the number of application level objects and check whether the debug mode is active or not.So, those are the basic properties that we have accessed from the HttpContext class, there are many more that you can access in the same way.3. Please keep in mind that, before going to this experiment you need to implement Windows Authentication in the application, then you will only get the proper value of those properties.Here is sample output of the above example. c# httpclient post no content.

Hi thanks for the comment :) In the first test you see I do the assert Assert.NotNull(retrievedPosts);, so it's there I would have it.Because my demo code GetPosts and CreatePost is simple it doesn't feel natural to add more assertions. Returns a Task that will yield an object of the specified type from the content instance. This is perfect for cloning http context with session state so subsequent threads can have access to session variables as well as the context properties.
