Member is obsolete

• Apr 29, 2019

CodeRush Classic displays the Member is obsolete code issue in a XAML document if the current member has the Obsolete attribute.

Fix

Use another member instead of the obsolete member.

Purpose

Highlights the reference to an obsolete member, which would cause the ‘Member is obsolete’ warning.

Example

C#

[Obsolete("Use 'MyNewClass' instead.")]
public class MyClass
{
  . . .
}

XAML

<Window x:Class="MyApplication.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:local="clr-namespace:MyApplication"
        Title="MainWindow" Height="500" Width="400">
    <Grid>
        <Grid.Resources>
            <local:MyClass x:Key="MyClass"/>
        </Grid.Resources>
        <local:MyControl 
            MyClassProperty = "{StaticResource MyClass}"
        />
    </Grid>
</Window>

Fix:

XAML

<Window x:Class="MyApplication.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:local="clr-namespace:MyApplication"
        Title="MainWindow" Height="500" Width="400">
    <Grid>
        <Grid.Resources>
            <local:MyNewClass x:Key="MyClass"/>
        </Grid.Resources>
        <local:MyControl 
            MyClassProperty = "{StaticResource MyClass}"
        />
    </Grid>
</Window>
