Hangfire – .NET Background Tasks

Introduction

In this article, We will discuss about the Hangfire, an open source framework, which is used to run background tasks in .NET. In general, we may need an application which run’s in the background based on the code nature, that is, it may take long time to execute and users does not want to bother about those task. We will have what are Background Task in the separate section, in this article.

Hangfire

As said before, Hangfire is an Open source framework, which simplifies the Processing and Managing Background Jobs in a reliable way. In an application, there may be have some occasion to run code in Background, that may be for a long run or may be based on the schedule. Hangfire will simplifies those background jobs, by Creating, Processing and Managing. Hangfire can be used in any type of .NET Applications.

Background Jobs

In the previous two sections, you are noticing about Background Jobs. Now you may think, what is a Background Job and when those are required. In .NET, some codes which needs to be run in the background because running it on the main thread is not appropriate, due to its nature or due to a specific requirement.

As for an example, in this article, we will create Greetings Scheduler application, which sends Greetings in Mail to the members. In simple, say for an organisation, they will have HR application and they will feed employee details. So from that data, they can schedule Birthday Wishes, Anniversary wishes Automatically. They do not need to check every month and send wishes in Mail.

Note:

This is Part one article and in this article we will have a detailed view on the Hangfire, how to install in our application and the background jobs that Hangfire can perform. The next article (last one), we will have a detailed view on Creating, Performing and Managing Background Jobs and we will apply the best practices.

Features of Hangfire

We should know why to use Hangfire over the windows job scheduler.

  • Hangfire is Simple to use. We do not need the Windows Scheduler for Background jobs.
  • Management and Visibility of the jobs. Hangfire’s provides a Dashboard, so that we can monitor, review, re-run and keep a track of all our jobs.
  • Reliability of Jobs. Hangfire ensures that our Background Job fires at least once. It does by storing our jobs in the database. If our jobs stops in a half way due to exception, Hangfire will automatically re-run the job and marks the job completed only when it is completed. How Hangfire marks as completed is, it ensures all the lines of code are executed, then only it marks as completed.
  • Can be Distributed or simple.

Hangfire’s Background Jobs

This is section, we will have what are the background job types provided by Hangfire. We will implement these types with our application in the next article. Now let’s have the job types,

  • Fire and Forget Jobs
  • Delayed Jobs
  • Recurring Jobs
  • Continuation Jobs
  • Batch Jobs
  • Batch Continuations

jQuery Ajax CRUD in ASP.NET Core MVC with Modal Popup

In this article, we’ll discuss how to use jQuery Ajax for ASP.NET Core MVC CRUD Operations using Bootstrap Modal. With jQuery Ajax, we can make HTTP request to controller action methods without reloading the entire page, like a single page application.

To demonstrate CRUD operations – insert, update, delete and retrieve, the project will be dealing with details of a normal bank transaction. GitHub repository for this demo project : https://bit.ly/33KTJAu.

Sub-topics discussed :

  • Form design for insert and update operation.
  • Display forms in modal popup dialog.
  • Form post using jQuery Ajax.
  • Implement MVC CRUD operations with jQuery Ajax.
  • Loading spinner in .NET Core MVC.
  • Prevent direct access to MVC action method.

Create ASP.NET Core MVC Project

In Visual Studio 2019, Go to File > New > Project (Ctrl + Shift + N).

From new project window, Select Asp.Net Core Web Application_._

Once you provide the project name and location. Select Web Application(Model-View-Controller) and uncheck HTTPS Configuration. Above steps will create a brand new ASP.NET Core MVC project.

Showing project template selection for .NET Core MVC.

Setup a Database

Let’s create a database for this application using Entity Framework Core. For that we’ve to install corresponding NuGet Packages. Right click on project from solution explorer, select Manage NuGet Packages_,_ From browse tab, install following 3 packages.

Showing list of NuGet Packages for Entity Framework Core

Now let’s define DB model class file – /Models/TransactionModel.cs.

public class TransactionModel
{
    [Key]
    public int TransactionId { get; set; }

    [Column(TypeName ="nvarchar(12)")]
    [DisplayName("Account Number")]
    [Required(ErrorMessage ="This Field is required.")]
    [MaxLength(12,ErrorMessage ="Maximum 12 characters only")]
    public string AccountNumber { get; set; }

    [Column(TypeName ="nvarchar(100)")]
    [DisplayName("Beneficiary Name")]
    [Required(ErrorMessage = "This Field is required.")]
    public string BeneficiaryName { get; set; }

    [Column(TypeName ="nvarchar(100)")]
    [DisplayName("Bank Name")]
    [Required(ErrorMessage = "This Field is required.")]
    public string BankName { get; set; }

    [Column(TypeName ="nvarchar(11)")]
    [DisplayName("SWIFT Code")]
    [Required(ErrorMessage = "This Field is required.")]
    [MaxLength(11)]
    public string SWIFTCode { get; set; }

    [DisplayName("Amount")]
    [Required(ErrorMessage = "This Field is required.")]
    public int Amount { get; set; }

    [DisplayFormat(DataFormatString = "{0:MM/dd/yyyy}")]
    public DateTime Date { get; set; }
}

C#Copy

Here we’ve defined model properties for the transaction with proper validation. Now let’s define  DbContextclass for EF Core.

#asp.net core article #asp.net core #add loading spinner in asp.net core #asp.net core crud without reloading #asp.net core jquery ajax form #asp.net core modal dialog #asp.net core mvc crud using jquery ajax #asp.net core mvc with jquery and ajax #asp.net core popup window #bootstrap modal popup in asp.net core mvc. bootstrap modal popup in asp.net core #delete and viewall in asp.net core #jquery ajax - insert #jquery ajax form post #modal popup dialog in asp.net core #no direct access action method #update #validation in modal popup
