In this blog post, we'll explore how to use in-memory caching in ASP.NET Core. Caching can highly enhance the performance of your web application by reducing the number of times data needs to be retrieved or computed. We'll use a simple example to illustrate how you can implement in-memory caching in your ASP.NET Core application. Setting Up the Project First, let's set up our ASP.NET Core project. We'll start with the HomeController class, which will handle our web requests. Here's the code for our HomeController: public class HomeController : Controller {     private readonly ILogger<HomeController> _logger;     private readonly IMemoryCache _memoryCache;     public HomeController(ILogger<HomeController> logger, IMemoryCache memoryCache)     {         _logger = logger;         _memoryCache = memoryCache;     }     public IActionResult Index()   ...

Introduction: In many web applications, there arises a need to perform certain tasks in the background at regular intervals, such as sending emails, updating caches, or fetching data from external sources. ASP.NET Core provides a easy way to achieve this through hosted services. In this blog, will walk through the process of creating a simple background task scheduler using ASP.NET Core's hosted services feature. Step 1: Creating a New ASP.NET Core Web Application Launch Visual Studio. Click on "Create a new project". In the "Create a new project" window, select "ASP.NET Core Web Application" and click Next. Project Name: Enter SampleBackgroundService. Location: Choose a location to save your project. Click Next. Step 2: Creating the Background Service Create a new class named MyBackgroundService.cs in your project and implement the background task logic. This class should inherit from BackgroundService and override the ExecuteAsync method...

Using Query Strings for Request Culture and Simplifying Localization with IStringLocalizer Interface Let’s see how to implement Localization in ASP.NET Core MVC. In the first example, I am going to use the IStringLocalizer Interface in the controller to implement Localization. Additionally, when the user passes the desired language through the query string, it will display content in that language. First, let’s configure the settings in the program.cs file. builder.Services.AddLocalization(options => options.ResourcesPath = "Resources");  The AddLocalization method adds the localization service to the service container. I have added the supported cultures here. I have added two cultures: en for English and nl for Dutch. In the RequestCultureProviders , I have included QueryStringRequestCultureProvider() . This allows the system to determine the culture information from the query string. UseRequestLocalization initializes a RequestLocalizationOptions o...

Introduction: In this blog, I'll walk you through the process of setting up an Entity Framework Core project with a focus on Microsoft SQL Server as the database provider. Setting Up the Database: To begin, we created two tables, namely "Students" and "Teachers," in the "SampleDB" database. This forms the foundation for our data model. Creating the MVC Project: Next, we initiated a new MVC project using Visual Studio. Installing Necessary Packages: In the Package Manager Console, execute the following commands to install the essential packages for Entity Framework Core: Install-Package Microsoft.EntityFrameworkCore.SqlServer Install-Package Microsoft.EntityFrameworkCore.SqlServer.Design Install-Package Microsoft.EntityFrameworkCore.Tools Microsoft.EntityFrameworkCore.SqlServer: Installs the required package to enable Entity Framework Core with Microsoft SQL Server as th...

Are you ready to enhance your ASP.NET Core MVC project with the power of Identity? In this comprehensive guide, we'll walk you through the process of setting up and customizing the Identity system in your web application. By the end of this tutorial, you'll be able to implement secure user authentication and authorization for your ASP.NET Core project. Step 1: Create a New ASP.NET Core Web App Begin by opening Visual Studio and selecting "ASP.NET Core Web App (Model-View-Controller)" as your project template. Follow these steps: 1. Open Visual Studio and create a new project, selecting "ASP.NET Core Web App (Model-View-Controller)". 2. In the "Configure your project" window, enter the project name and choose the project's location. 3. In the "Additional Information" window, select the framework and choose "Individual Accounts" as the Authentication type. 4. Click "Create" to generate your project....

Introduction: Azure Functions provide a serverless computing platform for executing code in a scalable and event-driven manner. One of the key triggers available in Azure Functions is the Timer trigger. With Timer triggers, you can schedule and automate the execution of your functions based on a specified time or interval. In this blog post, we will dive into the Timer trigger for Azure Functions and explore its features, use cases, and implementation. What is a Timer trigger in Azure Functions? The Timer trigger in Azure Functions allows you to schedule the execution of your functions at regular intervals or specific times. It is ideal for automating recurring tasks, periodic data processing, or triggering workflows based on a fixed schedule. With Timer triggers, you can define the timing using either a time expression or a more advanced cron expression. Key Features and Benefits Flexibility: Timer triggers support various time formats, including simple intervals, specific t...

Introduction: Blazor is a powerful framework for building web applications using C# instead of JavaScript. It allows developers to create interactive and dynamic user interfaces with ease. One of the key features in Blazor is the EventCallback<T> pattern, which enables communication between components through events. In this blog post, we will explore how to use the EventCallback<T> pattern in Blazor by building a simple example. Creating the Event-Driven Component: Let's start by creating a Blazor component called MyComponent. This component will raise an event when a button is clicked. Here's the code for the MyComponent.razor file: MyComponent.razor < h3 > My Component < / h3 > < button @onclick = " RaiseEvent " > Raise Event < / button > @code { [ Parameter ] public EventCallback < string > EventRaised { get ; set ; } private async Task RaiseEvent ( ) { await EventRais...

Azure Functions is a serverless computing service provided by Microsoft Azure, enabling developers to create applications without worrying about server maintenance and infrastructure. Using Azure Functions, developers can create event-driven, scalable, and highly available applications. In this blog, we will explain how to create an Azure function using Visual Studio 2022 with C# as the programming language. Before we begin, there are some prerequisites to consider. You will need an active Azure account subscription, Visual Studio 2022, and Azure Functions and Azure Storage extensions for Visual Studio. Step 1: Creating a new Azure Functions project in Visual Studio To create a new project, open Visual Studio 2022 and click on "Create a new project". In the "Create a new project" window, search for "Azure Functions" and select "Azure Functions" from the list of project templates. Next, enter the project name, which ...
