What are .Net Core Worker Services?

.Net Core 3 has introduced a new feature which is called as “Worker Services”. Worker services is a new project template that is considered to provide an initial point to write long-running background services in .NET Core. These background services execute the IHostedService interface; therefore, they are called “hosted services”. The peculiar fact about this is that dependency injection is available natively, which was not the case with a Windows Service created with Top Shelf. They can be delivered as a Windows service and also Linux daemons. A .Net core worker service generally performs a periodic background task, for instance sending out notification e-mails. Many modern cloud applications run at least some of them to make sure smooth sailing. These worker services solidify the position of the .NET ecosystem as a background development stack. .Net core background services help the client websites and .Net Core Web Development companies in reducing burden in a significant way.

Steps to create a new worker service application

Prerequisite for creating a new Worker Service in ASP .NET Core 3.0 includes

Some experience and knowledge with .Net Core is essentially required-

Steps to follow:

First of all, open the Visual Studio. Now let’s create an ASP.Net Core project with the following steps:

(i)  Launch Visual Studio

(ii)  Project template selection

(iii)  create new project

(iv)  worker service template selection

Some key benefits of .Net Core Worker Services

Dependency Injection

The .Net Worker Service template configures a default Dependency injection container which is ready for the developers to use. This is a great advantage compared to the generic Console template.

Configuration

For .Net Core Worker Services, the same configuration provider setup for ASP.NET Core are copied here. It eventually provides the developer with a stable and familiar environment for storing configuration-related information such as Logging. Likewise, logging providers have been configured to match the default setup for ASP.Net Core, providing developers with the following providers:

Worker Startup Class

The Worker.cs file is the place where the bulk of developer code exists. Three overridable procedures from the base class BackgroundService let developer tie into the lifecycle of their application:

Wrapping up 

The new worker service template in .NET Core 3 creates a hosting environment that is well-suited for console applications, containerized applications, cross-platform background services, and microservices. While these advantages can be configured independently of the template, the .Net Core Worker Service template provides us with a consistent start-up environment between ASP.NET Core and Console applications.
