Static members that initialize with other static members depend on document order

Description

Static members that initialize with other static members depend on document order.

Motivation

A static field or property initialized with another must be declared after.

public class Foo
{
    public static readonly int Value1 = Value2;

    public static readonly int Value2 = 2;
}

In the above example Value1 will be initialized with 0 which is likely not the intention.

How to fix violations

Declare members with dependencies in correct order.

public class Foo
{
    public static readonly int Value2 = 2;

    public static readonly int Value1 = Value2;
}

Configure severity

Via ruleset file.

Configure the severity per project, for more info see MSDN.

Via #pragma directive.

#pragma warning disable GU0023 // Static members that initialize with other static members depend on document order
Code violating the rule here
#pragma warning restore GU0023 // Static members that initialize with other static members depend on document order

Or put this at the top of the file to disable all instances.

#pragma warning disable GU0023 // Static members that initialize with other static members depend on document order

Via attribute [SuppressMessage].
