BinaryWrite exception “OutputStream is not available when a custom TextWriter is used” in MVC 2 ASP.NET 4

Question

I have a view rendering a stream using the response BinaryWrite method. This all worked fine under ASP.NET 4 using the Beta 2 but throws this exception in the RC release:

Answer 1

I did Levi's answer. It's actually super easy. My code writes an image to the response, which is previously gotten from the file system after various checks.

public class BookImageResult : ActionResult
{
    private readonly GraphicReport graphicReport;

    public BookImageResult(GraphicReport graphicReport)
    {
        this.graphicReport = graphicReport;
    }

    public override void ExecuteResult(ControllerContext context)
    {
        var response = context.RequestContext.HttpContext.Response;
        response.Clear();
        response.ContentType = graphicReport.ContentType;
        response.BinaryWrite(graphicReport.Image);
        response.End();
    }
}

The line at the end of the controller just looks like this:

return new BookImageResult(graphicReport);

Someone mark Levi's response as the answer!
