Issue #20: Indecent Exposure

Type: Encapsulation Violation
Files: BlogPost.cs, BlogComment.cs

Problematic Examples:

1. Public setters in domain models:

public string Title { get; set; } // Should be private set

2. Exposed collection:

public IList<BlogComment> Comments { get; set; } // Modifiable from outside

Solution:

private readonly List<BlogComment> _comments = new();
public string Title { get; private set; }
public IReadOnlyList<BlogComment> Comments => _comments.AsReadOnly();
