.NET 5 Dependency Injection

Join us Thursday, April 8, 2021, 16:00 – 17:00 CEST (10:00 AM – 11:00 AM EDT or check other timezones) for our free live webinar, .NET 5 Dependency Injection, with Steve Collins.

Register now and get a reminder, or join on YouTube

Since the release of .NET Core (now.NET 5), more developers are making use of dependency injection by using the default Microsoft Dependency Injection container that comes out of the box with .NET Core. This default implementation is sometimes limited in what it can do when compared to the features found in other containers available for the platform. In addition, there are some pain points that you may encounter if you have not read all of the documentation.

This talk will take you beyond the basics of the Microsoft container and covers more complex topics such as:

  • Explaining the limitations of the default container
  • Integrating with other DI containers
  • Perceived conflicts between service lifetimes
  • Understanding the Root and Scoped service providers used with different lifetimes
  • Thread safety and avoiding memory leaks, particularly with Singletons
  • Understanding deliberate and unintended multiple registrations
  • Registering and resolving classes with multiple interfaces
  • Registering and resolving multiple class implementations of a single interface
  • Registering and resolving open generics
  • Keyed and named registrations are not supported … but I need it!
  • How traditional design patterns such as Factory, Builder and Decorator can be integrated
  • Using delegate functions over OOP interfaces and classes
  • Automated service registration

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.

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

Getting Started with ASP.NET Core Dependency Injection

I’ve lately been feeling my way around getting an actual, production-ready ASP.NET Core app developed, and one of the features I’ve really been digging (one of many) is native support for Dependency Injection (DI). DI is huge in modern web apps, so making it the default for ASP.NET

How Tag Helpers for JavaScript and CSS Files Work with ASP.NET Core 5 MVC ?

Latest: https://youtu.be/LyVZySzKoI8 (Unit Testing Blazor ASP.NET 5) In this lecture, I have explained the Tag Helpers for JavaScript and CSS files in an ASP.NET Core 5.0 application.
Previous Part: https://youtu.be/R2LqSzpWQ4c
The lecture covers:
Tag Helpers for JavaScript Files
Cache Busting feature from ‘asp-fragment’ Tag Helper
Including JavaScript files from Content Delivery Networks using Tag Helpers
Tag Helpers for CSS Files
Including CSS files on the View
Excluding CSS files on the View
Including CSS files from Content Delivery Networks using Tag Helpers
This tutorial follows up on the previous tutorial at
https://youtu.be/R2LqSzpWQ4c where I have started on a product repository with an in-memory collection with an ASP.NET Core 5 MVC application.
Tag Helpers are used to performing defined transformations on HTML elements.
Enable server-side code to participate in creating and rendering the HTML elements in Razor files.

Online Snacks Ordering System with ASP.NET 5 Razor Pages(Working with Data) - Part 5

Previous (Part 4): https://youtu.be/D6-y7dnM4hE
Next (Part 6):

This is part 5 of a Razor Pages series of tutorials for an online snacks/desserts ordering system.
In this part, working with data is shown in the Visual Studio Code project. You will focus on using the SnacksContext to retrieve data for display on the home page and the ordering page, which has yet to be added to the application. The ordering page is also added in this tutorial.

This step-by-step Razor Pages tutorial series demonstrates how to create a Razor Pages application from scratch, and how to add common functionality to it including communicating with a database, working with forms, and sending an email.
