Class modifiers

The .NET Multi-platform App UI (.NET MAUI) x:ClassModifier attribute specifies the access level for a generated class in an assembly, provided that x:Class is specified on the same XAML element. This enables types to be hidden in libraries, so that they aren't accessible to consumers.

Valid values of the x:ClassModifier attribute are:

• Public – specifies that the generated class has no access restrictions.
• Internal – specifies that the generated class is accessible only within types in the same assembly.
• NotPublic – identical to Internal.

The value of the x:ClassModifier attribute must align with the access level of the type in its code-behind file.

By default, if the value of the attribute isn't set, the generated class will be public.

Note

The value of the attribute can use any casing, as it will be converted to lowercase by .NET MAUI.

The following XAML shows an example of setting the attribute:

<ContentPage xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             x:Class="MyMauiApp.MainPage"
             x:ClassModifier="NotPublic">
    ...
</ContentPage>
