Why Dot Net Core?

Dot Net Core is a free, cross-platform, open-source framework for building modern, cloud-based, and internet-connected applications. It supports a variety of applications, from web to mobile to desktop, and provides a consistent programming model. Here are key reasons why many developers prefer Dot Net Core:

• Platform Independence: Dot Net Core can run on Windows, Linux, and macOS, giving developers the flexibility to deploy applications across different environments.
• Performance: Known for its high performance, the framework optimizes apps to run faster and handle more requests, which is crucial for user satisfaction.
• Microservices Ready: It supports building microservices architecture, enabling developers to create scalable and robust solutions.
• Community Support: With its open-source nature, Dot Net Core boasts a vibrant community that contributes to its improvement and offers a wealth of libraries.

Now let's dive into the dos and don'ts that every Dot Net Core developer should know. This guide will help streamline your development process and ensure you avoid common pitfalls.

The Dos of Dot Net Core Development

1. Do Keep Your Dependencies Updated

Dot Net Core and its libraries are continually being improved. Stay updated with the latest version of Dot Net Core and associated packages to leverage the latest features, performance improvements, and security patches.

2. Do Follow Established Coding Standards

Adhering to industry-standard coding practices improves code readability and maintainability. This includes consistent naming conventions, documentation, and a logical project structure.

3. Do Implement Unit Testing

Testing is a crucial aspect of software development. Implement unit tests to validate your code functionality, which helps identify bugs early and ensures code quality.

4. Do Use Dependency Injection

Dot Net Core provides built-in support for dependency injection, which aids in creating loosely coupled code. This practice enhances the testability and maintainability of applications.

5. Do Optimize Data Access

Efficient data access is essential for performance. Use technologies like Entity Framework Core wisely, and ensure proper indexing of databases and efficient query practices.

6. Do Embrace Asynchronous Programming

Utilizing async and await keywords in Dot Net Core can drastically enhance your application's scalability by allowing it to efficiently handle multiple operations simultaneously.

The Don'ts of Dot Net Core Development

1. Don't Ignore Security Practices

Security should never be an afterthought. Always validate and sanitize inputs, use HTTPS, protect against threats like SQL injection, and regularly update dependencies to fix known vulnerabilities.

2. Don't Overcomplicate Your Application Architecture

While it's tempting to use complex patterns and architectures, simplicity often leads to more maintainable and manageable solutions. Keep the architecture straightforward unless complexity is justified.

3. Don't Neglect Documentation

Documentation is vital for onboarding new developers and ensuring knowledge transfer within the team. Lack of documentation can lead to increased onboarding time and difficulties in maintenance.

4. Don't Hardcode Configuration Settings

Utilize configuration files and environment variables instead of hardcoding settings. This practice enhances flexibility and enables easy configuration changes without modifying the codebase.

5. Don't Misuse Exception Handling

Improper exception handling can make debugging challenging. Only catch exceptions you can handle and allow others to propagate. Logging exception details is essential for troubleshooting.

6. Don't Forget to Clean Up Resources

Neglected resources, like database connections or open files, can lead to resource leaks, affecting performance. Ensure proper disposal and finalization of resources to maintain optimal application performance.

Conclusion

Dot Net Core's versatility and power make it a formidable choice for application development. However, to fully harness its potential, developers must adhere to best practices and avoid common pitfalls. By following these dos and don'ts, you can enhance your development process, create high-quality applications, and pave the way for a successful career as a Dot Net Core developer.

Remember, the technology landscape is ever-evolving, and continual learning is essential. Stay curious, adapt to new trends, and contribute to the Dot Net community to maintain a competitive edge in your development journey.
