Sudden Bad Request - Invalid Verb on during debugging Visual Studio
<p>During development I suddenly started to receive following error message</p>

<pre><code>Bad Request - Invalid Verb

HTTP Error 400. The request verb is invalid.
</code></pre>

<p>The website under development was run on ISSExpress via Visual Studio. It stopped working out of the blue, without any changes in the configuration.</p>

<p>I'm using: ASP MVC, C#</p>

<p>What can be the cause?</p>
