    <p>We've reverted to using request.InputStream in Web API due to this problem (<a href="http://aspnetwebstack.codeplex.com/SourceControl/changeset/9c76bb9090490541a453fcead75485ea50b88022" rel="noreferrer">commit 9c76bb9090490541a453fcead75485ea50b88022</a>).</p> <p>JimmiTh's answer correctly notes a discrepancy between the initial release notes and the implementation. As implied in the <a href="http://msdn.microsoft.com/en-us/library/system.web.readentitybodymode.aspx" rel="noreferrer">later documentation mentioned above</a> (though it is not particularly clear), request.GetBufferlessInputStream(), request.GetBufferedInputStream() and request.InputStream (along with Form, Files, etc.) are three mutually exclusive methods of request body access.</p> <p>It appears that, contrary to the <a href="http://www.asp.net/web-pages/overview/whats-new/whats-new-in-aspnet-45-and-visual-web-developer-11-developer-preview" rel="noreferrer">initial release notes</a>, request.GetBufferedInputStream() is not currently usable unless no other callers for the same request use any of InputStream, Form, Files, etc. I'm also following up to see if something better can be done compatibility between these two methods.</p> <p>David</p> <p>An update after talking with the product team: Calling request.GetBufferedInputStream() or request.GetBufferlessInputStream() means "I'm handling the stream explicitly myself; take me into advanced mode where automatic stream processing is disabled." However, in the case of buffered only, the members that normally rely on automatic stream processing (Form, Files, InputStream, etc.) are re-enabled after the buffered stream has been fully read.</p> <p>So, as the exception message hints, touching any of those properties before finishing reading the stream will fail:</p> <pre><code>public ActionResult Index() { Request.GetBufferedInputStream(); var ignore = Request.InputStream; return View(); } </code></pre> <p>But doing so after finishing reading the stream will succeed:</p> <pre><code>public ActionResult Index() { var stream = Request.GetBufferedInputStream(); new StreamReader(stream).ReadToEnd(); var ignore = Request.InputStream; return View(); } </code></pre> <p>The documentation isn't particularly clear here; I'll ask the product team if they can improve it.</p> <p>We're planning on switching back to GetBufferedInputStream in Web API; we'll just make sure it plays better with MVC in terms of when this call happens relative to consuming the stream and MVC executing.</p>

    1. COThanks for the update, David - glad I wasn't *completely* off - haven't looked much at the Http implementation, and the documentation in this case is confusing, to say the least. :-)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
