== Why is this an issue?

Fields and auto-properties that are never assigned to hold the default values for their types. They are either pointless code or, more likely, mistakes. 


=== Noncompliant code example

[source,csharp]
----
class MyClass
{
  private int field; // Noncompliant, shouldn't it be initialized? This way the value is always default(int), 0.
  private int Property { get; set; }  // Noncompliant
  public void Print()
  {
    Console.WriteLine(field); //Will always print 0
    Console.WriteLine(Property); //Will always print 0
  }
}
----


=== Compliant solution

[source,csharp]
----
class MyClass
{
  private int field = 1;
  private int Property { get; set; } = 42;
  public void Print()
  {
    field++;
    Console.WriteLine(field);
    Console.WriteLine(Property);
  }
}
----

=== Exceptions

* Fields on types decorated with `System.SerializableAttribute` attribute.
