Thank you for the video. It is good explained and complete. It help me a lot on understanding how work with HttpClient.

14:02 - Why should it never change? What if I have a derived client with more specific requirements? If I want a base client which defines a base URL, but then I inherit it to define actions on a particular resource in that service, then I will want to adjust the BaseAddress to add the path part to the URI.
Or should we never inherit from typed HttpClients because of the socket exhaustion thing? I can't find a good example on how to write clean, resource specific consumers.

Man, I love all your videos. Do you have a full tutorial that covers all of API .net core?

Hi, I love your tutorial and video.

I have a question tho, HttpClientFactory does not have the option to add parameters for the request, while HttpClient has that option, correct? I am having a problem with my target API; it takes two parameters, and I need to figure out how to add two parameters to my request. Would you mind explaining how I make that call with HttpClientFactory, please?

My target API signature looks like "public string Authentication(string UN, string AP)"

Where is the best place to put your method that calls an existing REST endpoint? Is it a controller? A service layer? A separate layer? I know you still have to register it on the startup, but what's the best place architecturally?

Everything looks clean and exactly what I am looking.

Question: How can we pass the Token to the API Client from WEB-Application (MVC Project) on Login Success?

[ivanvincent]

Great videos.. What interests me most is your mental model and how it allows you to code with such ease and flow. What would say are the key learnings to develop with the fluency you demonstrate? Cheers.

How would one go about replacing the HttpClient's base address after the service has been registered? Say this was for a desktop application and the user wanted to update the address that the application interfaces with

In the case of blazor client side does the http only cookies get sent with each request after they are created by the server?

Thank you, this was the first material I found on HTTP communication between APIs. I follow your simplest example, with a named HTTP client. I run both APIs via IIS and on the consumer set as a base address of the HTTP client the IIS-generated URL of the source API. Then I call my consumer controller method where on the client I call GetFromJsonAsync and as a parameter specify the path from the respective source API method I am interested in. This returns Not Found. Any idea what I'm doing wrong?

[jhbonarius]

is there something like this (required?) for WebClient? I need the DownloadFile method.

First of all, this is a very good tutorial, a bit fast so had to watch several times though :). I have a question, maybe a stupid one, so apologise in advance and correct me if I am wrong. when adding a typed HTTP client to the service collection and injecting a HttpClient in the constructor, wouldn't it be doing the same things as creating a new instance of the httpclient or is it still using the pool to create clients?
Cheers

А почем асинхроный метод ты выполняешь как синхроный ? Просто бросилось в глаза, в самом начале видео в методе Bad GetStringAsync()

[oguz]

Thank you for this great video, I've spent days finding solutions to some of the issues you mentioned in the video. I wish you had recorded this a few months earlier :) and for the viewers, please follow everything he says in the video to avoid having headaches :)

altough, there is something I still can't find a solution for, which is to change the proxy details on every call. as you know there is no way to change the proxy details once you created the httpclient, and I can't create a new httpclient instance due to issues you mentioned in the video. so I'm not sure if there is a solution but I'd really appricate if you have any solution for this, nevertheless it's a great video

Amazing video and amazing channel as well! My suggestion is to create the same video for WCF factory.
Thanks a lot!

Can you teach us Web Api, Node, react ?
