Visual Studio Code – MAUI Unable to use string resource file (resx) in XAML

I’m using Visual Studio 17.4.4 on Windows.

Everything I’ve read says this should be working, but I get:
XamlC error XFC0000: Cannot resolve type "MyApp.Resources.Localization:AppStrings"
What am I missing?

Here’s the xaml:

<ContentPage xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             xmlns:local="MyApp.Resources.Localization"
             xmlns:views="clr-namespace:Jetty_Mobile.Views"
             x:Name="thisPage"
             x:Class="MyApp.MainPage">
    <VerticalStackLayout
        Spacing="25"
        Padding="30,0"
        VerticalOptions="Center">
        <Label Text="{x:Static local:AppStrings.AppName}" />
    </VerticalStackLayout>
</ContentPage>

Looking for AppStrings in code behind works:

public MainPage()
{
    InitializeComponent();
    var thisworks = MyApp.Resources.Localization.AppStrings.AppName;
}

Here is a pic of the resx file

And here is AppStrings.Designer.cs

                }
                return resourceMan;
            }
        }
        
        /// <summary>

                return resourceCulture;
            }
            set {
                resourceCulture = value;
            }
        }
        
        /// <summary>
        ///   Looks up a localized string similar to My App.
        /// </summary>
        public static string AppName {
            get {
                return ResourceManager.GetString("AppName", resourceCulture);
            }
        }
    }
}

I have searched all over the web and everything I see says this should work, but it doesn’t.

    "{x:Static local:AppStrings.AppName}"

    The error message suggests that local:AppStrings is the wrong syntax to use inside of a property string. AFAIK, those xmlns are for xml element names; e.g. immediately after <.

    Try:
    "{x:Static MyApp.Resources.Localization.AppStrings.AppName}"

    (I’m not sure what syntax is, to shorten it.)

    It should be xmlns:local="clr-namespace:MyApp.Resources.Localization"

    I have created a sample to test your code:

    In the xaml:

    <ContentPage xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             xmlns:local ="clr-namespace:JsonData.Resources.Localization"
             x:Class="JsonData.MainPage">
 <Label Text="{x:Static local:AppStrings.AppName}"/>

    The resource file:

    enter image description here

    And then, the label will show the right value. And when I deleted the clr-namespace in the xmlns:local. I met the same error as yours.
