10 Practical C# Tips for Clean and Reliable Code

In this blog post, we’ll explore top 10 Practical C# Tips for Clean and Reliable Code.

Sharing a few coding practices I follow in my projects - hope you find them helpful too!

1. Prefer async/await for non-blocking code.
2. Always pass CancellationToken with async methods.
3. Use .AsNoTracking() in EF Core queries when tracking isn’t needed.
4. Avoid manually creating objects-leverage Dependency Injection.
5. Use HttpClient or HttpClientFactory - avoid deprecated classes like WebRequest.
6. Don’t catch generic Exception - be specific.
7. Always validate user inputs
8. Avoid string interpolation in logs - use structured logging instead.
9. Use using statements to dispose IDisposable objects properly.
10. Check IsSuccessStatusCode with HttpClient—avoid EnsureSuccessStatusCode() if you don’t want exceptions.
