Android emulator not showing in Visual Studio
<p>I made an Android Virtual Device. It runs on the SDK emulator using Intel HAXM. 
I was able to see it in Visual studio (debug devices drop down list) and debug my applications on it. This is great for when I don't have a physical device to hand.
Then <strong><em>something</em></strong> happened!?! It refuses to show up now?</p>

<p>Over the last week I have tried (In no particular order):</p>

<ul>
<li>Recreating my virtual device.</li>
<li>Reinstalling visual studio.</li>
<li>Reinstalling Android SDK.</li>
<li>Installing both of the above as an administrator.</li>
<li>Checking the SDK path in the windows registry.</li>
<li>Tried adb kill-server / start-server.</li>
<li>Checked that Adb can see the device - it can.</li>
<li>Tried uninstalling/reinstalling HAXM manually.</li>
<li>Made sure my project targets API of the emulator.</li>
<li>Made sure that the build active configuration matches the emulator.</li>
<li>Ended any other ADB processes using task manager (leaving just the one for visual studio).</li>
<li>Checked windows event log for any warnings/errors. Nothing.</li>
</ul>

<p>I have read these. Also no joy...</p>
