Customizing ASP.NET Core Part 9: ActionFilter

This post is a little late this time. My initial plan was to throw out two posts of this series per week, but this didn’t work out since there are sometimes some more family and work tasks to do than expected.
Anyway, we keep on customizing on the controller level in this, the ninth, post of this blog series. I’ll have a look into ActionFilters and how to create your own ActionFilter to keep your Actions small and readable.
