I can normally debug my web service with no problem, but now I persistently get error "Unable to launch the IIS Express Web Server. Port 3268 is in use". I have looked at previous questions about this, but I am stuck:
it doesn't matter what port I use
rebooting, closing web browser, deleting web history etc all fail
tools like TCPView show that the port is NOT in use
I can start/stop IISExpress from a command prompt OK
normally, address localhost:3268 shows an error message in a browser - but after loading the project in Visual Studio (and BEFORE starting to debug the project, or doing anything at all to it), localhost:3268 shows a web page in the browser

The Solution Restart the computer. Add the port you are using to the port exclusion range: netsh int ipv4 add excludedportrange protocol=tcp startport=50403 numberofports=1 store=persistent. Reenable Hyper-V. Restart the computer.
By default, you can use IIS Express to run your website using a non-reserved port such as 8080. However, using a reserved port such as 80 or 443 requires work.
If you are running the Development Application Server, changing the port used by the server is the easiest solution. Change the Server Port in the Application Server Control Panel and start the server. Specify a port that is not 80, such as 8080. Changing the port number may not desired in a Production environment.
Closing IIS Express By default Visual Studio places the IISExpress icon in your system tray at the lower right hand side of your screen, by the clock. You can right click it and choose exit. If you don't see the icon, try clicking the small arrow to view the full list of icons in the system tray.
I was having these issues with specific projects.
For me,
netstat -ano at the command line. The solution was to run
netsh http add iplisten ipaddress=::
from the command line.

1, firs click properties.
After that click "Create Virtual Directory" button. Then debug and run.
I hope this will solve your problem

You can change the port of the website from the website properties under the web ribbon, specifying a different port other than 3268.
Also a link from the Stackoverflow discusses the same scenario
Why and how to fix? IIS Express "The specified port is in use"

The link that Krishna provided inspired me to open IIS and discover that there was a local web site in IIS with the same port (it was the same web service). I deleted that, and now I can debug my application again.
I cannot explain why I couldn't see the port in use, why it started offering the web page when the project was loaded in Visual Studio, and why I couldn't see that IIS was running in the task manager. I am guessing that Visual Studio was actually running it somehow.
Thanks to all respondents for their help!
