Initialize properties with default values

Set sensible defaults for properties/fields or enforce via constructors.

Why this matters

Prevents null/invalid states and clarifies invariants.

Side-by-side examples engineers can pattern-match during review.

Avoid

public string Status { get; set; } // never set

Prefer

public string Status { get; set; } = "Pending";

Bad

string Name {get;set;}

Good

string Name {get;set;} = string.Empty;

From the same buckets as this rule.

Critical
Avoid equality operators in loop termination conditions
Check if loops use equality operators (== or !=) in termination conditions. These can lead to infinite loops if the condition is never met exactly. Instead, use relational operators like < or > for safer loop termination.

Critical
Avoid Returning Null in Non-Async Task Methods
Returning null from a Task or Task<T> method causes a NullReferenceException if awaited. Use Task.CompletedTask or Task.FromResult<T>(null) instead.

Critical
Avoid Using Boolean Expressions in `except` Statements
Detect `except` clauses that use `or` or `and` to catch multiple exceptions. This does not work as intended. Recommend using a tuple of exceptions instead.
