I found temporary cross-platform solution for .NET Core to read system memory metrics until framework level libraries appear. This blog post shows how to build ASP.NET Core health check for system memory metrics.

It’s time to get back to old era of this blog and bring my vCard action result to today’s ASP.NET Core world. There’s also support for images so we can provide really good looking vCards from ASP.NET Core applications. This blog post gives a good base for custom vCard solutions in ASP.NET Core.

We all probably know how to inject instance of interface to class using dependency injection in ASP.NET Core. But how can we inject all instances of interface to some class, let’s say controller, using dependency injection? The trick is simple and it’s shown in this blog post.

Thing I left out from my post about ASP.NET Core health checks was the old legacy system we all know. It works and nobody wants to touch it. Other systems must be very careful with it because it is easy to break it down with load. Of course, there’s no way for us to replace or fix the elder monster. Here’s how to make sure we don’t take it accidentally down with too frequent ping checks or ping flood.
