Why is this an issue?
Marking a method with the Pure attribute specifies that the method doesn’t make any visible changes; thus, the method should return a
result, otherwise the call to the method should be equal to no-operation. So Pure on a void method is either a mistake, or
the method doesn’t do any meaningful task.
Noncompliant code example
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
class Person
{
private int age;
void ConfigureAge(int age)
{
...
this.age = age;
}
...
}
