I love Restsharp for its automatic serialization/deserialization of JSON objects, and thanks for this article too. Please can you do one article of injecting Restsharp as a dependency inject on .NET 6? I find it challenging to set global configs, i.e. base_url to be set under the appsettings.json, please guide

Thank you for the input Donnie. We’ve covered Refit as well.

Flurl is a great library as well. We have an article covering Flurl too.

Thank you for the info. We are aware of how HttpClientFactory works and why it should be used, but for this article, we mainly wanted to compare HttpClient and RestSharp. But as you can see in the article, we had to mention HttpClientFactory and link to our article about it.

The true magic of HttpClient is the underlying HttpClientHandler… this is what is expensive to create, and the lifetime/allocation of this is managed by the HttpClientFactory. HttpClient is, itself, only a wrapper around the handler.

Looking at the source for RestSharp, it creates a new handler for each instance of the RestClient. There is no object pooling or reuse of the handler.

I would strongly not recommend RestSharp as it will not scale.

Consider benchmarking using the HttpClientFactory, you should see a marked difference

Why not compared with (de)serialization and httpClient since that is part of restsharp?

I’ve been using Refit for the last 2+ years. https://github.com/reactiveui/refit

Can’t imagine not having it. And it leverages HttpClientFactory.

In reply to James.

Hello James. I agree with you but this is not the topic of this article. As you can find in this article we’ve linked a Page with several HttpClient articles: https://code-maze.com/httpclient-with-asp-net-core-tutorial/ One of those is about HttpClientFactory and why and how you can use it. Whatsoever, we even linked that one in this article (Re-opening the connection is a costly process that can cause socket exhaustion. We can prevent this issue with HttpClientFactory to create and manage HttpClient instances.) That said, this article is mainly about comparison.

I encourage you to use IHttpClientFactory instead of HttpClient to prevent socket exhaustion.
