asp.net mvc - localhost refused to connect Error in visual studio

Question

I have copied my solution file from another system and tried to run it on my machine: For this, I have gone to the project folder and deleted the previous solution file and copied the new one.

Now, it started giving me error. connection refused etc. So, I got one solution from here: How to solve ERR_CONNECTION_REFUSED when trying to connect to localhost running IISExpress - Error 502 (Cannot debug from Visual Studio)?

According to it, I changed the port number from 1049 to 1052. It loaded and one of the pages gets loaded. But when I entered the desired login credentials then it redirected to the older port again, like this:

http://localhost:1049/Home/SearchFlight

and the error is:

 This site can’t be reached

 localhost refused to connect.
 Search Google for localhost 1049 Home Search Flight
 ERR_CONNECTION_REFUSED

Now, I don't know what to do from here. I have changed the port number to 1052 but still its pointing to 1049. What should i do now?

I had a similar issue. Try this and it should work

1. Go to your project folder and open the .vs folder (keep your check hidden item-box checked as this folder may be hidden sometimes)

2. In the .vs folder open the config folder

3. See that applicationhost.config file there? Delete that thing. (Do not worry it will regenerate automatically once you recompile the project.)
