ASP.NET 5 web app not running in debug mode in IIS Express

Question

Completely following this Tutorial including the prerequisites described there, I created the web app ContosoBooks using VS2015 Professional on Windows 7. The app compiles successfully but when I run the app in debug mode using F5 in Visual Studio, it waits for a long time and finally gives me this error: The project properties are set to default as follows:

The windows event log shows the following message: The directory specified for caching compressed content C:\Users\myname\AppData\Local\Temp\iisexpress\IIS Temporary Compressed Files\Clr4IntegratedAppPool is invalid. Static compression is being disabled

The project.json file is as follows:

Why are you hitting localhost:50711 when your project settings indicate that the website is hosted at localhost:49723? — Camilo Terevinto

@cFrozenDeath I've reloaded the image1 that shows localhost:49723. The old image was from when first time I had created this project. After I got this error, I deleted the project and recreated it, hence the port number was changed from 50711 to 49723. The error is still exactly the same. — nam

Is this on your development machine? You could try to enable the full IIS from Windows' Add or Remove Features — Camilo Terevinto

@cFrozenDeath It's our local machine and I verified using this MSDN article that the trust level is set to Full. — nam

I didn't mean the trust level, I meant IIS version. What I'm saying you should do is install the full (not express) version of IIS, and change the project to use that. — Camilo Terevinto

Commenting out app.UseBrowserLink() in the startup.cs allowed me to use Bitdefender Endpoint Security and ASP.Net 5.

I found this work around on the asp.net github page.

Thank you for providing a workaround. I specially appreciate you pointing out to the github link related to this issue. I've BitDefender installed and this workaround resolved the issue.

I have the exact same issue, and I've found a reason for it: Bitdefender AV. Completely uninstalling Bitdefender (download an uninstaller from their site) resolved the problem for me. Why Bitdefender interferes with running an ASP.NET 5 application, I cannot understand. I've registered a support ticket with Bitdefender, but haven't received any reply yet.

The problem with Bitdefender and Visual Studio 2015 can be resolved by simply uninstalling and installing of Bitdefender. Probably the issue was removed from the new distributions of the software.
