"The member "X" is not recognized or is not accessible." error in WPF-CodePudding

I'm trying to make an interface with multiple language options on a WPF screen. I'm writing the name of the text block I want to add to my Resources file and my code, but on the xaml screen "The member "Manuals" is not recognized or is not accessible." I get an error. I am getting this error in all the buttons and texts I try to add. Can you help me understand why? There is my xaml code line and resources designer cs project code line. Thanks in advance.

public static string _Manual
    {
        get
        {
            return ResourceManager.GetString("Manuals", resourceCulture);
        }
    } 

<TextBlock  Name="ttbManuals" Grid.Row="8" Text="{x:Static resx:Resources._Manual}" HorizontalAlignment="Left" Margin="0,0,0,-20"  VerticalAlignment="Top" Height="39" Width="580" Style="{DynamicResource CncTextBlock}" Background="{DynamicResource BackgroundBrush1}" Padding="10,5,0,0"/>

CodePudding user response：

The Resources class is by default created as internal. For use in XAML it needs however to be public.

To fix it, select the resx file in solution explorer and in the properties, change ResXFileCodeGenerator to PublicResXFileCodeGenerator.
