Correctly updating a ``++static++`` field from a non-static method is tricky to get right and could easily lead to bugs if there are multiple class instances and/or multiple threads in play.
This rule raises an issue each time a ``++static++`` field is updated from a non-static method or property.
== Noncompliant Code Example
----
public class MyClass
{
private static int count = 0;
public void DoSomething()
//...
count++; // Noncompliant
}
