Unable to Launch IIS Express Web Server - VS 2015 Community
<p>I am developing a web project and I am not being able to test it using the IIS Express from the Visual Studio 2015.</p>

<p>I have googled this error and I found many references to it on the internet, but I believe that my case is different, because there is no other error message displayed besides "Unable to Launch IIS Express Web Server".</p>

<p>I've looked at the Windows Event Viewer and I got these errors below:</p>

<pre><code>The worker process failed to initialize correctly and therefore could not be started.  The data is the error.

The Module DLL C:\Program Files (x86)\IIS Express\aspnetcore.dll failed to load.  The data is the error.
</code></pre>

<p>I also tried to launch the IIS Express directly using: <code>c:\Program Files (x86)\IIS Express&gt;iisexpress.exe /trace:error</code> and I was successfull, so I think that the problem must be somewhere within Visual Studio and that my port (8080) is free.</p>

<p>Does anyone knows what else I can do?</p>
