✅ Best practice usage of HttpClient in .Net Framework 4.5

Hello everyone 👋 hope you’ll. Are having a good day/evening. What is the recommended approach of using http client in a dot net framework 4.5.2 project ? Please note that I’m not able to use dependency injection in this project

"What is the recommended approach to do X? By the way, I can't use the recommended approach." I guess you could create some singleton kind of a class with a static HttpClient If you don't use it much, chances are a single instance of it will be fine. If you use more, you'll need some code that will manage instantiating and destroying more of them

like this right ?

private static readonly HttpClient client = new HttpClient();

public void MakeRestCall(string url){
  var response = await client.GetAsync(uri);
}

private static readonly HttpClient client = new HttpClient();

public void MakeRestCall(string url){
  var response = await client.GetAsync(uri);
}

Currently have 3 classes which uses httpclient, and since each of these make a http request to 3 different baseurl's, does this mean that I will need 3 more static instances of httpclient ?

when using static instance of an httpclient, does that mean defaultrequestheaders cant be set again ? say if the auth token changes ?
