Preloading some data at application startup as fast as possible
I am caching some very static information (changes once per day) in my ASP.NET Core application. This is normally done when needed ("lazy").

One such cache item is a 50K list of items that are taking less than 500ms when the application is deployed and about one second in the development environment.

However, one colleague has a slower Internet connection and this takes several seconds to complete. 

One solution to keep the caching and make things faster for my colleague is to start the fetch ("eager load") in parallel with the API startup. 

How can I do this in ASP.NET Core?
