Implement Rate Limiting In ASP.NET Core Web API

-
Image
Introduction In this article, you'll learn about rate limiting and how to apply it to your ASP.NET Core Web API. What is Rate Limiting? If you're building an API, it might be accessed by multiple clients. Sometimes, certain clients use the API excessively without any restrictions. However, if you need to control how often a specific client can use the API within a set timeframe, you can achieve this through Rate Limiting. Rate Limiting is like setting a speed limit on how many times someone can ask for something from a website or app in a certain amount of time. It means each person or device using the service can only ask for a certain number of things within a particular timeframe. Why do we need Rate Limiting? Rate Limiting is a useful tool for safeguarding against harmful bot attacks. Imagine a hacker sending bots to repeatedly request access to an API endpoint. This flood of requests can ove...

The Key Features of .Net 8

-
Having a regular schedule for releasing .NET updates is great. In the past, when using the older .NET Framework, updates were infrequent and didn't bring significant changes. While it wasn't necessarily a problem, the issue was that the development platform's progress was linked to Windows updates, which could mean waiting for years to access new features. Since transitioning to an open-source platform, especially with the simultaneous development of .NET Core and the .NET Standard base classes, and later the integration into a unified .NET, there have been significant improvements. Now, we receive a yearly update for .NET, connected to the .NET Conf event held in November. These updates come with 18 months of support for STS (Standard Term Support) releases and three years of support for LTS (Long Term Support) releases. It's worth noting that STS releases are odd-numbered versions, while even-numbered versions are designated as LTS. ...

ASP Net Core Cookie Authentication With SPA

-
ASP.NET Core is a fantastic framework for web applications, representing a significant leap in architecture design compared to ASP.NET MVC. However, as I began working with it, I noticed it has strong opinions about how certain things should be done. These preferences are evident not just in the framework itself but also in various tutorials and blog posts created around it. If you prefer doing things in your own way, finding assistance can be challenging. One common preference is using the Authorization header token authentication, like JWT, for Single Page Applications (SPA). Personally, I struggled to find tutorials or documentation explaining how to use cookie authentication for SPAs in ASP.NET Core. I won't get into the ongoing debate about whether this idea is good or not, as there are plenty of blog posts and videos discussing it already. In this article, I will show you how I managed to set up cookie authentication in a Single Page Applica...

Should you adopt .NET 7 or wait for .NET 8?

-
  Introduction Is waiting worth it, even in the realm of software frameworks? As technology keeps progressing, new and better frameworks are introduced to match the latest innovations like AI. With the imminent arrival of .NET 8, developers might be curious about what makes it a better choice than .NET 7. In this post, we'll delve into the improvements that make .NET 8 an excellent option for developers aiming to stay at the forefront of technology. But if you're using .NET 7 now, don't rush; there's time to consider your options. Better Performance In every new version of .NET, making things faster is a top priority. .NET 8 takes a step beyond .NET 7 by refining the Just-In-Time (JIT) compiler, garbage collector, and runtime. This means applications start up more quickly, use less memory, and perform better overall. These improvements make .NET 8 a great choice for developers who want to optimize their applications and make them...

Custom Middleware in .Net core 6.0

-
Image
  We will now write a custom middleware to avoid inline middleware in Program.cs.  The custom middleware will be written to a different class. Please keep the following in mind when writing custom middleware. There are several components that must be included in the middleware class: RequestDelegate is a public constructor with a parameter. Invoke or InvokeAsync is a public method that should return a Task. HttpContext should be the first parameter With IApplicationBuilder, an extension method is created for exposing the Middleware. Dependency Injection can be used to populate additional parameters for the constructor and for Invok/InvokeAsync. Let's quickly dive into Visual Studio and start building a middleware. In this tutorial, I'll be utilizing the following tools: Visual Studio Community Edition 2022 (64-bit) .NET 6.0 Minimal Web API Swagger There are three different methods ...
