Response Caching with MediatR in ASP.NET Core

In this article, we are going to implement Response Caching with MediatR in ASP.NET Core using its awesome Pipeline Behaviours. I have written a couple of articles about MediatR and why it’s one of the MUST USE libraries for .NET devs. This library simplifies your Application to an extent yet gives you complete control.What’s Response Caching With MediatR?

In a previous article, we discussed the Pipeline Behavior of MediatR and how Logging and Validation of Requests can be implemented. In this post, let’s go one step further and implement Caching in the MediatR pipeline. This means that every response that is sent out of your application (API) will be cached by your application with a very simple implementation.

Caching is quite a lifesaver at times for any application. It helps you reduce the round-trip time from the client to server to the database, and probably saves you $$$$ by minimizing the database calls. When it comes to caching in ASP.NET Core, you are presented with a whole lot of options. Few of them are as follows –

• Redis Distributed Caching
• In-Memory Caching

However the decision on where the caching happens is quite vital. There are several other questions that can arise when you deal with caching.

• How long should the cache stay?
• Which part of the application flow should be responsible for caching?
• How to bypass cache if needed?
• Do you need to write cache code all throughout the application? or is there a simpler way?
• How to invalidate cache if needed?

MediatR Pipeline Behavior is the answer for all these questions. Given that you are already using CQRS with MediatR, why not use it to its complete potential.

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.

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.

MVC User Registration & Login with ASP.NET Core Identity

User registration and authentication are mandatory in any application when you have little concern about privacy. Hence all most all application development starts with an authentication module. In this article, we will discuss the quickest way to use **ASP.NET Core Identity for User Login and Registration **in a new or existing MVC application.

Sub-topics discussed :

• How to add ASP.NET Core Identity to MVC application.
• Customize ASP.NET Core Identity.
• Identity.UI Design Customization.
• Next step.

Background

ASP.NET Core Identity is an API, which provides both user interface(UI) and functions for user authentication, registration, authorization, etc. Modules/ APIs like this will really be helpful and fasten the development process. It comes with ASP.NET Core Framework and used in many applications before. Which makes the API more dependable and trustworthy.

ASP.NET Core MVC with user authentication can easily be accomplished using Identity.UI. While creating the MVC project, you just need to select Authentication as Individual User Accounts.

The rest will be handled by ASP.NET Core Identity UI. It already contains razor view pages and backend codes for an authentication system. But that’s not what we want in most of the cases. we want to customize ASP.NET Core Identity as per our requirement. That’s what we do here.

Create an ASP.NET Core MVC Project

First of all, I will create a brand new ASP.NET Core MVC application without any authentication selected. We could add ASP.NET Core Identity later into the 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. A new window will be opened as follows, Select _Web Application(Model-View-Controller), _uncheck _HTTPS Configuration _and DO NOT select any authentication method. Above steps will create a brand new ASP.NET Core MVC project.

Running WordPress on ASP.NET Core with Peachpie

In this article, you will learn how to use or integrate WordPress in ASP.NET and Running WordPress on ASP.NET Core, without PHP, or any source files on the server. The following demonstration will show you how to add WordPress as a frontend to an existing ASP.NET Core application step by step.

Running WordPress on NET Core

WordPress is a free, simplest, and most popular open-source content management system to create your own website or blog which is written in PHP and paired up with MySQL. WordPress on .Net Core is possible with peachpie, which is a compiler built on top of the Roslyn platform, it’s a set of runtime and base class libraries and everything that allows compiling a PHP project, a group of PHP files into a regular .net project.

Peachpie allows for seamless both-way interoperability between PHP and .NET applications. In simpler terms, this means that one can have some parts of an application written in PHP, while other modules are written in .NET and everything will work together as one application. Here is the original Repository of the WordPress SDK by PeachPie.

Here are the following steps to run WordPress with ASP.Net Core:-

Step1: Open your Visual Studio IDE and Create a new project – > ASP.NET Core Web Application

Step 2: Select Web Application: A project template for creating an ASP.Net Core application with example ASP.Net Razor Pages Content.
