What are the differences between using ConfigureAwait(false) and Task.Run?

Question

I understand that it\'s recommended to use ConfigureAwait(false) for awaits in library code so that subsequent code does not run in the caller\'s e

Answer 1

As a side note, in both cases LoadPage() could still block your UI thread, because await client.GetAsync(address) needs time to create a task to pass to ConfigureAwait(false). And your time consuming operation might have already started before task is returned.

One possible solution is to use SynchronizationContextRemover from here:

public async Task LoadPage(Uri address)
{
    await new SynchronizationContextRemover();

    using (var client = new HttpClient())
    using (var httpResponse = await client.GetAsync(address))
    using (var responseContent = httpResponse.Content)
    using (var contentStream = await responseContent.ReadAsStreamAsync())
        return LoadHtmlDocument(contentStream); //CPU-bound
}
