Why is this an issue?
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
