Top 10 .NET Core Best Practices for Avant-garde Application Development

Following are the top best practices, tips, and tricks to follow for best-in-class application development.

  • Utilize the Latest Version
  • Configure Caching Mechanism
  • Reduce Exception Implementation
  • Use .NET Core Logging
  • Configure All-rounder Security
  • Take Advantage of Dependency Injection
  • Utilize AutoMapper
  • Prefer Async Methods
  • Implement Compression

#1: Utilize the Latest Version

Using the latest .NET core version is the most underrated yet fundamental best practice every developer must follow. It helps you to take advantage of the new-age functionalities and boost the business solution’s productivity. In addition, the latest versions are always an upgrade, helping you effortlessly align with the current market trends.

Moreover, you get the following advantages during development with the latest .NET Core version:

  • It helps to enhance the application compatibility across all devices.
  • It supports following the industry coding standards.
  • It removes the glitches, bugs, and errors present in the previous versions.

Additionally, you get the leverage of ongoing Microsoft support for your app. Otherwise, for outdated versions, you have to search for associated forums.

#2: Configure Caching Mechanism

When it comes to .NET Core development, you must implement a caching mechanism in the application. It will directly help you improve the performance and enhance the stability for all end-users. And it will provide an additional benefit of saving the cost of transmitting large objects repetitively.

In a .NET Core application, you should consider configuring the following caches:

  • Distributed Caching
  • In-Memory Caching
  • Distributed Cache Tag Helper
  • Cache Tag Helper

Additionally, if you are building an ASP.NET core software, you must include the response caching middleware through the following code:

public void ConfigureServices(IServiceCollection services)

Once you configure the code, the performance will be skyrocketing.

#4: Use .NET Core Logging

Whenever you are building an ASP.NET or .NET Core application, always enable logging and store all the entries on a separate server. It will help you debug and maintain the code after deployment effectively. You should ensure that the log structure must include the date, time, a short description, and information about the component creating it.

Furthermore, build a constant logging mechanism in the application to ease the tasks, such as:

  • Finding the issue and troubleshooting it.
  • Discovering the bug /error and resolving it.
  • Efficiently monitoring the application and retaining its overall metrics.
  • Creating security alerts and preventing unauthorized access.

#5: Configure All-rounder Security

Data and application security are the two primary concerns of every business and development firm. As a .NET developer, you must focus on the overall application security and configure the following controls:

  • Authentication to verify the identity of every user.
  • Authorization to provide only required access and controls.
  • Accountability to improve non-repudiation.

In addition, you should implement encryption using an SSL certificate for secure transmissions and hashing for safeguarding data in the storage. To prevent high-potential attacks, focus on the below configurations:

  • Data validation
  • Input sanitization
  • Access Control Lists
  • Code Signing
  • Log everything and more

If you are looking for the best security advice, consult a .NET development company, such as Positiwise Software Pvt Ltd, which has been in the domain for 21+ years.

#6: Take Advantage of Dependency Injection

Dependency Injection is a must-to-use feature of ASP.NET development technology. It aids in creating a loosely coupled application, providing better re-usability, maintainability, and testability throughout the application cycle.

Additionally, you should use all three dependency injections (Construction, Setter, and Interface-based) per requirements. It will help you build solid object contraction and helps to transmit dependencies whenever required. Also, it enables the test of every component in an isolated environment so that it doesn’t affect the other components.

Furthermore, after the software deployment, the DI will be highly supported during maintenance with its pluggable-replaceable functionality. Hence, dependency injection should be in your ASP.NET core app.

#7: Utilize AutoMapper

To avoid the boilerplate code in your application, you should use the AutoMapper. It only requires minimal resources and time to configure it. And you can use it for individualizing the view and the domain model. For configuring the separation, use the following code:

public class EmployeeService 
 private EmployeeRepository employeeRepository = new EmployeeRepository();
 public EmployeetDTO GetEmployee(int employeeId) 
 var emp = employeeRepository.GetEmployee(employeeId); 
 return Mapper.Map(emp); 

Furthermore, AutoMapper supports writing a clear codebase, which is easy to compile, debug, test, and run on all compatible platforms. It also uses less code for transmitting data, leading to saving resources and costs for the company. The less clustered code of AutoMapper is a reliable solution for source and destination model objection conversion.

#8: Prefer Async Methods

Asynchronous process execution is always beneficial, as it aids in enhancing performance and resource utilization. For ASP.NET applications, you can consider creating a thread pool following asynchronization. It will lead the application to process multiple user requests parallelly rather than queuing them and increasing the load.

In addition, you must comply with the following code standards:

Don’t use the following code:

public class WrongStreamReaderController : Controller
    public ActionResult<HomeData> Get()
        var json = new StreamReader(Request.Body).ReadToEnd();
        return JsonSerializer.Deserialize<HomeData>(json);

Use the below code instead of the above-provided code:

public class CorrectStreamReaderController : Controller
    public async Task<ActionResult<HomeData>> Get()
        var json = await new StreamReader(Request.Body).ReadToEndAsync();
        return JsonSerializer.Deserialize<HomeData>(json);

After implementing the correct code, your ASP.NET core app will prevent the chaining and callback nesting. Moreover, the errors will be managed simultaneously without impacting user experience, stability, and performance. 

#9: Implement Compression

Compression is a reliable option to improve the performance of your ASP.NET application. It works best with the caching mechanism and deployment of software over a content delivery network. You should configure it for every business software to improve the productivity and data transaction rate.

In addition, it reduces the processing time and provides the output within seconds to every end-user. Due to this, customer satisfaction and revenue increase. To implement the compression in code .NET core code, you can use the following code block:

public void ConfigureServices(IServiceCollection services_collection)
        (opt =>
            opt.Level = CompressionLevel.Fastest;

#10: Put JavaScript Loading For Last

As we know, JavaScript files are heavier than others and require more time to load. And if you configure your application to load JS files before other components, it can adversely impact the business’s marketing and performance. So, you should create a logic to load JavaScript files at the end.

As a result, the loading speed will increase, the end-user will see content within seconds, and the bounce rate will decrease. All the objectives, from technical to marketing, can be covered with later JS loading.
