    <p>I have an API for a system written using the ASP.NET Web Api and am trying to extend it to allow images to be uploaded. I have done some googling and found how the recommended way to accept files using MultpartMemoryStreamProvider and some async methods but my await on the ReadAsMultipartAsync never returns.</p> <p>Here is the code:</p> <pre><code>[HttpPost] public async Task&lt;HttpResponseMessage&gt; LowResImage(int id) { if (!Request.Content.IsMimeMultipartContent()) { throw new HttpResponseException(HttpStatusCode.UnsupportedMediaType); } var provider = new MultipartMemoryStreamProvider(); try { await Request.Content.ReadAsMultipartAsync(provider); foreach (var item in provider.Contents) { if (item.Headers.ContentDisposition.FileName != null) { } } return Request.CreateResponse(HttpStatusCode.OK); } catch (System.Exception e) { return Request.CreateErrorResponse(HttpStatusCode.InternalServerError, e); } } </code></pre> <p>I can step through all the way to:</p> <pre><code>await Request.Content.ReadAsMultipartAsync(provider); </code></pre> <p>at which point it will never complete.</p> <p>What is the reason why my await never returns?</p> <h1>Update</h1> <p>I am attempting to POST to this action using curl, the command is as follows:</p> <pre><code>C:\cURL&gt;curl -i -F filedata=@C:\LowResExample.jpg http://localhost:8000/Api/Photos/89/LowResImage </code></pre> <p>I have also tried using the following html to POST to the action as well and the same thing happens:</p> <pre><code>&lt;form method="POST" action="http://localhost:8000/Api/Photos/89/LowResImage" enctype="multipart/form-data"&gt; &lt;input type="file" name="fileupload"/&gt; &lt;input type="submit" name="submit"/&gt; &lt;/form&gt; </code></pre>

    3. COPut a breakpoint in the code after the `await` as well. Sometimes it doesnt break/step to the next line when you're using async/await (from my experience)

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.

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