?????? ???? ???????? ?????????????????? ?????????????

Adhering to best practices improves code quality, scalability, and maintainability while reducing bugs and technical debt.

Today, let's explore 9 Best Practices in .NET Core that every developer should know. ??

1. ?????? ???????????????????? ?????????????????? (DI) ??:

Leverage .NET Core’s built-in DI container to manage dependencies and write cleaner, testable code. Example:

services.AddScoped<IUserService, UserService>();        

2. ?????? ???????????????????? ??:

Use the built-in ILogger for structured and consistent logging, making debugging a breeze.

_logger.LogInformation("Application started at {Time}", DateTime.UtcNow);        

3. ?????????????????? ?????? ???????????????? ??:

Store sensitive data and app configurations in appsettings.json or environment variables.

4. ???????????? ???????? (??????????-???????????? ???????????????? ??????????????) ??:

Securely allow or restrict API access from other domains. Example:

app.UseCors(builder => builder.AllowAnyOrigin().AllowAnyMethod().AllowAnyHeader());        

5. ?????????????????? ??????????/?????????? ??:

Write non-blocking code to improve performance and scalability.

public async Task<IActionResult> GetUsersAsync()  
{  
    var users = await _userService.GetAllUsersAsync();  
    return Ok(users);  
}        

6. ???????????? ???????? ???????? ??:

Implement token-based authentication (JWT) and use HTTPS for secure data exchange.

7. ???????????? ???????????????????? ???????????????????? ??:

Use global exception handling middleware to catch and respond to errors in a consistent way.

8. ?????? ???????????????????? ??:

Simplify object-to-object mapping, especially in larger applications.

var userDto = _mapper.Map<UserDto>(user);        

9. ?????????? ???????? ?????????? ??:

Test your controllers, services, and business logic to ensure reliability.
