How can I read the file contents using http synchronously

Question

In an event that is called synchronously, so I can't use await (so no IHttpClientFactory), what is the correct way to read the contents of a file.

I am using the following, and it works. But the compiler is telling me I should not use WebClient.

And to repeat, I have no choice in the matter - this cannot be an async method.

public byte[]? GetContent(IBlobService blobService, string blobUrl)
{
    using (var client = new WebClient())
    {
        return client.DownloadData(blobUrl);
    }
}

Answer 1

why can't you use IHttpClientFactory? You can make the HttpClient async call sync with .GetAwaiter().GetResult().

var buffer = httpClient.GetByteArrayAsync(blobUrl).GetAwaiter().GetResult();
