C# Tip: Evite usar exceções para controle de fluxo Exceções devem ser usadas para erros inesperados, não como parte do fluxo normal do programa. Usar try-catch para controlar lógica pode prejudicar a performance e dificultar a leitura do código. ✅ Prefira verificações explícitas com if, TryParse…

C# Tip: Prefer record over class for Immutable Data When you're modeling data that shouldn't change after creation (like DTOs or configuration models), using record types is cleaner, more expressive, and gives you built-in value-based equality. 🔧 Example: public record User(string Name, int Age)…

ASP.NET Core Tip When securing APIs with JWT Bearer Authentication, always validate the Audience and Issuer in TokenValidationParameters to prevent accepting tokens from unexpected sources: services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme) .AddJwtBearer(options => {…

C# Tip: Use default Literal for Cleaner Code Initialization Since C# 7.1, you can use the default literal instead of verbose type initialization when assigning default values. ✅ Example: MyClass obj = default; int number = default; CancellationToken token = default; Instead of: MyClass obj =…

C# Tip: Use CallerArgumentExpression for Smarter Validation Since C# 10, the [CallerArgumentExpression] attribute helps you write better guard clauses and validation methods by capturing the original expression passed to a parameter. Example: void ValidateNotNull(object? obj…

ASP.NET Core Tip – Use ProblemDetails for Consistent Error Responses ASP.NET Core supports the ProblemDetails standard to return structured and standardized error messages from your APIs. ✅ Example: [HttpGet] public IActionResult Get() { return Problem( detail: "Resource not found."…

C# Tip: Use ConfigureAwait(false) in Libraries When you use await in a library (not in UI apps), consider using ConfigureAwait(false). ✅ Why? It prevents capturing the SynchronizationContext, avoiding potential deadlocks and improving performance in library code. Example: await…

C# Tip: Use using static to Simplify Code Starting with C# 6.0, you can import static members from a type directly into scope. This reduces repetitive class references and makes your code cleaner. ✅ Example: using static System.Math; public double CalculateCircleArea(double radius) { return PI…

C# Tip: Use Init-Only Setters for Immutable Objects Introduced in C# 9.0, init accessors let you set properties only during object initialization, combining immutability with a clean syntax — perfect for models and DTOs. ✅ Example: public class User { public string Name { get; init; }…

C# Tip: Use using var for Cleaner Resource Disposal Starting in C# 8.0, you can use using var to automatically dispose of resources without a block scope. This keeps your code clean and ensures deterministic disposal. ✅ Example: using var stream = new FileStream("log.txt", FileMode.Open); // Use…

C# Tip: Use ?. (null-conditional) and ?? (null-coalescing) Together You can safely access properties and provide fallback values in one line: var displayName = user?.Profile?.Name ?? "Guest"; This avoids null reference exceptions and makes your code cleaner. #csharp #dotnetdev #dotnet

C# Tip: Use readonly struct for Performance-Critical Value Types When designing small value types that are immutable, prefer using readonly struct. It prevents accidental mutations and can reduce defensive copies, improving performance. ✅ Example: public readonly struct Point { public int X {…

Tip – Use the readonly Keyword for Immutable Fields If you have fields that should only be assigned during declaration or in the constructor, mark them as readonly. This ensures the field’s value cannot change after construction, improving code safety and clarity: public class Customer {…

C# Tip: Use Dictionary.TryGetValue to Avoid Exceptions When retrieving values from a dictionary, prefer TryGetValue over direct indexing to avoid KeyNotFoundException. ✅ Example: if (myDictionary.TryGetValue("key1", out var value)) { Console.WriteLine($"Found: {value}"); } else {…

C# Tip: Use nameof with ArgumentNullException for Cleaner Validation When checking for null arguments, use nameof to avoid hard-coded strings and make your code safer during refactoring. ✅ Example: public void ProcessOrder(Order order) { if (order == null) throw new…
