=== Noncompliant code example

[source,csharp]
----
class Person
{
  private int age;
  [Pure] // Noncompliant. In this case the method makes a possibly visible state change
  void ConfigureAge(int age)
  {
    ...
    this.age = age;
  }
  ...
}
----


=== Compliant solution

[source,csharp]
----
class Person
{
  private int age;

  void ConfigureAge(int age)
  {
    ...
    this.age = age;
  }
  ...
}
