Change request's behavior

[freddy0448]

Is there a way to change the 'every request behavior' of a Refit Service?

What I want is to do some cleanup on my app's main thread. I want the request to be made in a different thread, something like:

var result = await Task.Run(async () => await HttpGet())

I'm not doing it on every request because will be headache and pretty hard to maintain. Any suggestions?

Refit returns a Task, so the actual HTTP call already runs off the calling thread - awaiting it does not block your main thread while the request is in flight. You generally do not need Task.Run for that.

A few options depending on what you actually want:

• If you just want to free the UI/main thread while the call happens: await the Refit method directly. The continuation resumes on the captured context. If you do not need the captured context for post-processing, add ConfigureAwait(false) at the call site.

• If you want all continuations to stay off the UI thread for an entire call chain, wrap the top-level call once: await Task.Run(() => api.HttpGet()). You do not need this per request.

• If you want to run logic on every request (logging, cleanup, threading), add a DelegatingHandler to the HttpClient pipeline rather than changing call sites. That runs for every request centrally:

services
    .AddRefitClient<IMyApi>()
    .ConfigureHttpClient(c => c.BaseAddress = new Uri("https://api.example.com"))
    .AddHttpMessageHandler(() => new MyHandler());

A DelegatingHandler is the maintainable place for cross-cutting per-request behavior.
