The project needs to be deployed before it can be started
<p>Whenever I am starting to test an Windows Phone app (even a blank app) on emulator, I am getting error "<strong>The project needs to be deployed before it can be started</strong>". The emulator will be started &amp; run successfully, still no luck in deploying app on emulator. <strong>Getting error DEP6100 &amp; DEP6200.</strong></p>

<p>These are the stuffs I tried till now:</p>

<ol>
<li>Checked "deploy" option in 'Configuration Manager'.</li>
<li>Tried deploying Windows 10 Mobile, Windows Phone 8.1 &amp; Windows Phone 8 blank apps on different types of emulators. </li>
</ol>

<p>Although I am able to run apps on my device.</p>

<p><em>I am running Visual Studio Enterprise 2015 on Windows 10 Enterprise.</em></p>
