ASP.NET Core offers many advancements over the ASP.NET MVC/Web API. Business sites are highly dependent on the performance of a website or an application. It consists of the site's load time, which is one of the key characteristics that discloses the success of your website.

So, if your website takes more than 3 seconds to load, there are chances that the users might leave the site or go to competitors' sites. If you are looking to offer services with a better user experience, your business needs to prefer a flawless and robust web app. For a performance-driven site, one of the best options is to choose an ASP Net development company.

Why Use ASP.NET Core?

  • With ASP.NET, businesses can create any web application and services, including IoT app development and mobile back-end development services.
  • You can work on any development tools like Linux, Windows, and Mac OS-X.
  • With ASP.NET, a developer can help you deploy the applications on the cloud and on-premise cloud.
  • Built-in asset for dependency injection.
  • Tag Helpers which make Razor markup more natural with HTML.
  • Capability to host on IIS or self-host in your process.

.NET Core Best Practices

Startup class and the service Configuration

We operated two methods in the startup class for service configuration for performance-driven web development. Both methods are equally important, and those are Configure Services and Configure methods.

The Configure Services technique is utilized to register the services.

And the Configure method is used to add the middleware components to the apps' pipeline. The best practice for any .NET app development is to keep the ConfigureServices process uncluttered and readable.

When you start using too many services, you have to register services inside the Configure Services method, and then it will not be either readable or clean. To avoid this concern, the dot net development company uses extension methods. It is known for the static approach, and it helps boost the readability of our code.


namespace project.test
	public static class ConfigureExtensions
		public static void CorsConfiguration(this IServiceCollection services)
		services.AddCors(options =>
			builder => builder.AllowAnyOrigin()

Once it's done, you can call this extension process on the startup file like below.

public class Startup
	public void ConfigureServices(IServiceCollection services)

Project Organization

Asp.net development companies should always break an app into smaller projects while developing. It is the best way to organize the project where project managers and developers can get a clear idea about app development and separation of concerns (SoC).

With years of experience in web and app development, we suggest keeping business logic in a separate .NET Core Class Library project. In addition, it must be associated with contracts, and entities, accessing the database, logging messages or sending email messages, and more. As shown in the image, each small project inside our application contains various folders for business logic organization.

Environment Based Settings

When an app is under development, it is considered in the development environment. As soon as the .NET app development is completed and it is time to publish the application, it will be in the production environment. These require an environment-based separate configuration for each environment and are considered best practices by the asp.net development company.

It is a very accomplished step in the .NET Core. Once a .NET developer develops the project, you will get the appsettings.json file. When developers expand it, you will see the appsetings.Development.json file.

All the settings inside this file will be used for the development environment. An ASP.NET developer should add another file appsettings.Production.json, to use it in a production and development environment.

Now, the production file will be set right under the development file, and with this setup in place, we can store various settings in the different app settings files. Besides, .NET Core will serve you in the right place, depending on your application's environment.

Optimize Data Access

Data access optimization is the key to improving the performance of the application. By going through the optimizing process, you can limit access to data logic. The majority of the .NET applications are completely dependent on a database, where the whole data process is done from the database, including processing it and displaying it.

With the help of a dot net development company, you can optimize your data access in the most suitable way.


  • There is no need to get the data in advance which is not required.
  • Employ non-tracking queries when recovering data for read-only reasons in Whole Framework Core.
  • Call all data access via the APIs asynchronously when you want to call data access.
  • Sum and filter LINQ queries like Where, Select, or Sum statements for the database to perform filter items.

Always Use Cache

One of the widespread and proven methods of improving site performance is Caching. Top software development companies should cache to store any relatively stable data. Asp.NET Core delivers response caching middleware support used to execute response caching.

We can use response caching to enhance output caching, and it can cache web server responses using cache-related headers to the HTTP response objects. Also, caching large objects avoids costly allocations.

Types of cache to be used:

  • Caching technique
  • Distributed cache
  • Cache tag helper
  • In-memory caching
  • Distributed cache tag helper

Use Content Delivery Network (CDN)

Even though the speed of light is fast, considering it as more than 299000 km/s, it also enables us to keep our data to our consumers. Besides, it will be easy to load on the server for bigger static files; you can use CDN if there are only numbered CSS and JS files.

Most CDNs have many locations and help files from a local server because loading files can improve the website's performance.

Use Swagger

Swagger is a machine-readable manifestation or a representation of a RESTful API. That RESTful API will support interactive documentation, client SDK generation and discoverability. It defines a RESTful API that authorizes discoverability, interactive documentation, and generation of Client SDK support.

Setting up a tool like Swagger usually takes just a couple of minutes. However, the benefits are enormous. You get a great tool that you can use to document your API. Also, you can use it to have an excellent overview and a way to test your API.


Structured logging is when we keep a consistent, fixed logging format. Using structured logs, it’s easy to filter, navigate, and analyze logs using structured logs.

Asp.Net Core has structured logs by default, and to keep the entire code consistent, the Asp.Net team will have to make it consistent. The web server communicates with the application. Serilog is an excellent logging framework that can be used for logging.

Advantages of ASP.NET Core

If we think of the roots of ASP.NET, it came from the two-legacy code: Web Forms and MVC. The performance wasn’t necessarily one of the more decisive points, but with .NET Core, it is one of the key advantages.

.NET core is designed to be integrated smoothly with different client-side frameworks, including Bootstrap, KnockoutJS & AngularJS. Finally, for better app performance &output, the ASP.NET Core app can deploy .NET Core or .NET Framework run-time.

Here are the advantages of ASP.NET Core:

  • Built & run on cross-platforms like Windows, Mac and Linux.
  • Single aligned web stack for Web UI and Web APIs.
  • Full command-line support
  • Modular deployment of .NET Core itself.
  • More easy tools to improve modern web development.
  • Tag Helpers that Razor markup more natural with HTML.
  • Interoperability with .NET Framework


We try to represent and spread knowledge about the best .NET practices for the business looking to develop a .net application. Implementing these best .NET practices will offer growth and strategies for Net Core. The app's performance will help you gain more customers and result in a faster and more seamless experience with our expertise.
