IIS Express gets stuck and css styles sometimes not being applied when debugging an ASP.NET MVC application from Visual Studio 2013

I am debugging an ASP.NET MVC app from Visual Studio 2013. When I start the debug process from Visual Studio, IIS Express where app is hosted gets stuck (my app is not started). It often happens to me. In this situation, I manually stop IIS Express from the tray icon. Even stopping IIS Express from the tray icon I often need to stop manually the debugging from Visual Studio through the stop button. Once debugging is stopped, If I try to debug again it does not work, well, sometimes works and sometimes not, it is random. I have verified that if I clear all browser history and cookies, it works in most cases except for some time. Also I have observed that Visual Studio 2013 takes a long time to boot IIS Express where my ASP.NET MVC app is hosted. Finally, I have observed that my ASP.NET MVC app hosted in IIS Express sometimes is not being displayed correctly when debugging from Visual Studio, I mean, it is displayed without css styles being applied, it seems like css styles are missed. In this case, if I stop debugging and start it again it works.

So How can I improve or solve these kind of weird issues?

“In this situation, I manually stop local IIS from the tray icon”. That's not local IIS, but IIS Express. - Lex Li
@LexLi Ok, I have updated my post. And do you know any kind of solution for this weird issues? - Ralph
The integration between IIS Express and VS is poorly documented, so it is non-trivial to tell what's up. - Lex Li
Changing the port number through right-click project name then properties, sometimes helps. However, you might try hosting on Local IIS. - A. Nadjar

This is a quite strange issue and l suggest you could try these suggestions

Suggestion

1) delete all caches under C:\Users\Administrator\AppData\Local\Microsoft\VisualStudio\12.0\ComponentModelCache, C:\Users\Administrator\AppData\Local\Temp and C:\Users\Administrator\AppData\Local\Microsoft\WebsiteCache.

2) close VS Instance, delete .vs hidden folder,bin,obj folder under the physcial path of the solution and then reopen your project

3) If you have IntelliTrace, please disable Enable IntelliTrace under Tools-->Options-->IntelliTrace-->General.

4) try another port like 56000 by right-clicking on the project-->Properties-->Web--> project url.

5) disable any third party extensions by Tools-->Extensions and Updates or just use devenv /safemode in developer command prompt for vs2013.

6) try to reinstall IIS on the control panel and if your IIS is not 10.0, I suggest you could download and use it.

In addition, VS2013 is too old and Microsoft does not continue to maintain it. So l suggest you could download and use the latest VS2019. It has more optimization and stronger performance than the previous VS and fixes some remaining issues from previous releases.
