Hot reload will not work if you make any changes that modifies the method signatures and so on. As for the issue that you are facing with changes not being updated after restart, it's likely that the browser is caching static assets in your app serving old files. To fix this issue you can either do a hard reload on your browser or go to browser settings to clear the browser cache. Also, it is a good practice to clean and rebuild the solution after you have made changes instead of just a restart.
