ASP.NET Core 2.2 introduces a range of new features. One of the more interesting (IMO) is Health Checks. You may use tools like Pingdom or elmah.io Uptime Monitoring to ping your website in a specified interval. Pinging a single HTML page may or may not reveal if your application is healthy or not. Health Checks to the rescue! Before trying out the code yourself, make sure to install the recent version of ASP.NET Core 2.2 and Visual Studio 2017.
