I’m in the process of upgrading a .NET Framework 4.7.2 project up to .NET 8, and am running into a compatibility issue with one of the existing methods. The method is shown below.

    public override async Task OnActionExecutedAsync(HttpActionExecutedContext actContext, CancellationToken token)
    {
        // If we can't accept gzip
        if ((actContext.Response == null || actContext.Response.Content == null) ||
            (actContext.Request.Headers.AcceptEncoding == null ||
            !actContext.Request.Headers.AcceptEncoding.Any(h => h.Value == "gzip")))
        {
            // Wait till the action is complete
            await base.OnActionExecutedAsync(actContext, token);

            // Exit
            return;
        }

        // Await the content stream
        var contentStream = await actContext.Response.Content.ReadAsStreamAsync();

        // Asynchronously push zipped stream to client
        actContext.Response.Content = new PushStreamContent(async (stream, content, context) =>
        {
            using (contentStream)
            using (var zipStream = new GZipStream(stream, CompressionLevel.Fastest))
            {
                await contentStream.CopyToAsync(zipStream);
            }
        });

        // Configure the headers
        actContext.Response.Content.Headers.Remove("Content-Type");
        actContext.Response.Content.Headers.Add("Content-Encoding", "gzip");
        actContext.Response.Content.Headers.Add("Content-Type", "application/json");
    }
}

The problem I’m running into is that HttpActionExecutedContext is not supported anymore. Is there an exact equivalent to it in .NET 8? I’ve tried using ActionExecutedContext but it doesn’t seem to have all the same properties for the Response class. For example .Content doesn’t seem to exist anymore as a property of Response.

Any suggestions or documentation on an equivalent class to HttpActionExecutedContext would be greatly appreciated. Thanks.
