• Brace Placement: Place opening braces on the same line as the statement they belong to, and closing braces on a new line.

  // Good
  if (condition)
  {
      // Code here
  }
  
  // Bad
  if (condition) {
      // Code here
  }
  

4.1.2 Naming Conventions

• Pascal Case: Use Pascal case for class names, method names, and property names.

  public class MyClass
  {
      public void MyMethod()
      {
          // Code here
      }
  
      public int MyProperty { get; set; }
  }
  

4.1.3 Language Features

• Expression-bodied Members: Utilize expression-bodied members for concise one-liners.

  // Good
  public int CalculateSquare(int x) => x * x;
  
  // Bad
  public int CalculateSquare(int x)
  {
      return x * x;
  }
  

• Null Conditional Operator: Use the null conditional operator (?.) for safe property or method access.

  // Good
  int? length = text?.Length;
  
  // Bad
  int length = (text != null) ? text.Length : 0;
  

4.2 Documentation
