The thought behind this addition was to allow us to re-use the tools that we use in ASP.NET, such as dependency injection and logging abstractions of Microsoft.Extensions. Later on, in ASP.NET Core 3.0 and 3.1, they moved ASP.NET to run on .NET Generic Host instead of the previously used WebHost, merging the two approaches together to make them truly the same. Now we can build our console applications, systemd’s, windows services or web apps on the same underlying hosting paradigm, with the same shared...

And every time the application was restarted, the memory would return to normal, and slowly creep upwards again. As you can clearly see, the application uses gradually more and more memory over time. Every time the line drops, was a restart...
