"The stream was already consumed."

Bug Report

Overview

When Debugging is enabled, the HTTP stream is read once again, and because of that, it throws an exception: The stream was already consumed.

To Reproduce

Steps to reproduce the behavior:
I used the same console app, which I have already given in the previous report.

Expected behavior

to dump whatever was supposed to.

Resolution proposal

Add the following lines at the BaseEndpointExtension ln:37

            if (baseEndpoint.EnableDebug)  // just before ReadAsStreamAsync(.. this will enable multiple reads of the stream.
            {
                await response.Content.LoadIntoBufferAsync().ConfigureAwait(false);
            }
            await using var stream = await response.Content.ReadAsStreamAsync(cancellationToken).ConfigureAwait(false);

so actual bug or enhancement to debug?

#> so actual bug or enhancement to debug?

Not sure what you mean :) Yep, I think it's a bug. Proposed resolution, I tested on my end; it works.
One more thing. I'm calling MCP that returns status notification like this:

But "progressToken" is null, and was never requested. Do you know maybe where to look for this? Ref to the discussion: [here](https://github.com//discussions/509)

Unsure, but open a new ticket/discussion for that one as well please.
