    CRR0046 - Redundant field initialization

    This analyzer identifies redundant field initialization values, which can be removed to improve code readability.

    public int sum = 0;

    To fix the issue, remove the field’s redundant default value:

    public int sum;

    Call the Remove Redundant Assignment refactoring to remove the redundant field initialization.
