Unable to connect to the configured development Web Server.

Asp.net using C#

I was running my website successfully, but one day when I tried to open it in Web Browser got this weird message which seems like a alert message:

Unable to connect to the configured development Web server.Failed to register URL "http://{ip_addr}:{port}/" for site "{project_name}" application "/". Error description: Access is denied. (0x80070005)

Tried many solutions nothing worked. 

 

Later on the following solution worked fine and I was able to run my website again.

Step 1: Open the .sln file with notepad or any text editor.

Step 2: Change your existing port number number with new port number which              is between range 44300-44399, so 44300 port then. This is the range              which is allowed without Administrative privileges.

 

Hope this solution will work for your project as it worked for mine.
