FLTFY12: Hide is disregarded when Ignore is applied

Type Name	FLTFY12_HideAttributeAnalyzer
Diagnostic Id	FLTFY12
Category	Usage
Severity	Info
Is Enabled By Default	Yes

Cause

The property is annotated with both Hide and Ignore.

Rule Description

A violation of this rule occurs when a property is marked with both the Hide and Ignore attributes. The Ignore attribute removes the property from Fluentify consideration entirely, so the Hide attribute is redundant and ignored.

For example:

[Fluentify]
public class Example
{
    [Hide, Ignore]
    public string Property { get; set; }
}

In this example, Fluentify will not generate extension methods for Property because Ignore takes precedence. The Hide attribute has no effect.

How to Fix Violations

Reevaluate whether the property should be excluded or merely hidden.

• If the property should be excluded from Fluentify, remove the Hide attribute.
• If the property should remain in Fluentify but be internal, remove the Ignore attribute.

For example:

[Fluentify]
public class Example
{
    [Ignore]
    public string Property { get; set; }
}

or alternatively:

[Fluentify]
public class Example
{
    [Hide]
    public string Property { get; set; }
}

When to Suppress Warnings

Warnings from this rule should be suppressed only if there is a strong justification for applying both Hide and Ignore.

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

[Fluentify]
public class Example
{
    #pragma warning disable FLTFY12 // Hide is disregarded when Ignore is applied
    
    [Hide, Ignore]
    public string Property { get; set; }
    
    #pragma warning restore FLTFY12 // Hide is disregarded when Ignore is applied
}

or alternatively:

[Fluentify]
public class Example
{
    [Hide, Ignore]
    [SuppressMessage("Usage", "FLTFY12:Hide is disregarded when Ignore is applied", Justification = "Explanation for suppression")]
    public string Property { get; set; }
}

How to Disable FLTFY12

It is not recommended to disable the rule, as this may result in confusion about which attribute is expected to take effect.
