For a "dotnet new web" project, if you try to make a change and hit save, you will not see the change even if you force refresh the browser

### Describe the bug
Hot Reload doesn't work when you create a new endpoint using minimal API, it doesn't even rebuild and refresh the browser, and when you force refresh the browser the changes are still not reflected.


### To Reproduce
- In WSL - Ubuntu 20.04 LTS
- Create a new web app using "dotnet new web"
- Use "code ." to open it in VS Code
- In the Terminal type "dotnet watch"
- Open the link in the browser
- Open Project.cs
- Create a new endpoint OR update the existing "Hello World" text
- Hit CTRL+S
- You will see the message "No hot reload changes to apply. Application restarting because changes were detected to the app's initialization code."
- At this point you would assume the changes have been reflected in the browser.
- If you goto the browser, it has not refreshed, and if you force refresh the browser, you will still not see the changes.
