How can I set a timeout for an Async function that doesn't accept a cancellation token?

Question

I have my web requests handled by this code;

Response = await Client.SendAsync(Message, HttpCompletionOption.ResponseHeadersRead, CToken);

Since returns a task, you can Wait for the Task which essentially is equivalent to specifying a timeout:

// grab the task object
var reader = response.Content.ReadAsStringAsync();

// so you're telling the reader to finish in X milliseconds
var timedOut = reader.Wait(X);  

if (timedOut)
{
    // handle timeouts
}
else
{
    return reader.Result;
}
