We will go over the purpose of minimal APIs in.NET Core 6, as well as how to implement them step by step.


  • .NET Core 6 SDK
  • Visual Studio 2022
  • SQL Server


  • Minimal APIs are used to create HTTP APIs with minimum dependencies and configuration.
  • Mostly, it is used in microservices that have fewer files and functionality within a single file.
  • But there are a few things that are not supported in minimal APIs, like action filters and built-in validation; also, a few more are still in progress and will get in the future by .NET Team.

Step-by-Step Implementation Using .NET Core 6

Step 1

Create a new .NET Core Web API.

  • Basic understanding of .NET Core 6 API and C#.
  • Visual Studio 2022
  • SQL Server


  • Create .NET Core API using version 6
  • Configure Hangfire in .NET
  • Look into the different types of jobs that are present in Hangfire.


  • Hangfire is open-source and used to schedule the job at a particular event and time.
  • It is also used to create, process, and manage your background jobs.
  • We use this in background processing without user intervention.
  • Hangfire is reliable and persistent. It will take care of all things once the job is scheduled.
  • Hangfire dashboard is also available for us to manage all things easily.

Why Hangfire is Required in Background Processing

  • Sometimes we need to do lengthy operations like database updates and database maintenance so it’s managed periodically. 
  • Batch import from XML, JSON, and YAML files.
  • Recurring reports on a periodic basis.
  • Mass notification on subscription and sign up basis.

So, these are things that we are able to do periodically over a certain period of time as per our requirements.

There are different types of jobs that are present in Hangfire. We will look at them one by one.

I am an « automation fundamentalist ». What I mean by that, is that I will go through large amounts of pain to avoid having to manually type code if I am able to have my computer do it automatically for me. The reasons are fairly self evident, because all bugs originates from a human being having written code at some point in time. Hence, if I can completely avoid manually writing code, the argument is that I can create 100% perfect software systems, that won’t even in theory be allowed to contain bugs of any kind. This idea extends to writing Unit Tests too.

Therefor, I created the ability to automatically generate Unit Tests in Magic. To understand how, watch the following video, where I demonstrate how I invoke an HTTP REST endpoint, for then to persist the invocation, allowing me to « replay » it later. The idea of course, is that being able to replay an HTTP invocation, can help me sanity check my system further down the road, as I modify it for whatever reasons I have to modify it.
