FLTFY02: Descriptor is disregarded from consideration by Fluentify

Type Name	FLTFY02_DescriptorAttributeAnalyzer
Diagnostic Id	FLTFY02
Category	Usage
Severity	Info
Is Enabled By Default	Yes

Cause

A property marked with the Descriptor attribute is also marked with the Ignore attribute, making the use of the Descriptor attribute redundant.

Rule Description

A violation of this rule occurs when a property is marked with the Ignore attribute, excluding it from consideration by Fluentify. Therefore, using the Descriptor attribute on such properties is redundant and should be avoided.

For example:

[Descriptor("Assign"), Ignore]
public string Property { get; set; }

In this example, Property is excluded from Fluentify's consideration due to the presence of the Ignore attribute, making use of the Descriptor attribute redundant, suggesting a misunderstanding by the engineer as to its intended usage.

How to Fix Violations

Reevaluate the decision to apply the Ignore attribute. If the Ignore attribute usage is deemed correct, remove the Descriptor attribute, otherwise remove the Ignore attribute.

For example:

[Descriptor("Assign")]
public string Property { get; set; }

or alternatively:

[Ignore]
public string Property { get; set; }

When to Suppress Warnings

Warnings from this rule should be suppressed only if there is a strong justification for the redundant use of the Descriptor attribute.

If suppression is desired, one of the following approaches can be used:

[Fluentify]
public class Example
{
    #pragma warning disable FLTFY02 // Descriptor is disregarded from consideration by Fluentify
    
    [Descriptor("Assign"), Ignore]
    public string Property { get; set; }
    
    #pragma warning restore FLTFY02 // Descriptor is disregarded from consideration by Fluentify
}

or alternatively:

[Fluentify]
public class Example
{
    [Descriptor("Assign"), Ignore]
    [SuppressMessage("Design", "FLTFY02:Descriptor is disregarded from consideration by Fluentify", Justification = "Explanation for suppression")]
    public string Property { get; set; }
}

How to Disable FLTFY02

It is not recommended to disable the rule, as this may result in some confusion if expected extension methods are not present.
