I am developing a web project and I am not being able to test it using the IIS Express from the Visual Studio 2015.
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".
I've looked at the Windows Event Viewer and I got these errors below:
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.
c:\Program Files (x86)\IIS Express>iisexpress.exe /trace:error
If you are working with .NET core/ASP.NET core application then please make sure you have installed these-
.NET Core SDK
VS 2015 Tooling Preview 2
If it is appeared to be solution-specific then-
Look for applicationhost.config file at
Try removing this file and run solution again.
See if this helps.
