XAML reference to System.Windows.Controls.BooleanToVisibilityConverter

In my WPF-application, targeting .NET Core 3.1, I'm trying to use the built-in System.Windows.Controls.BoolToVisibilityConverter

I think I have looked up the correct syntax for the XAML reference.

xmlns:controls="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls"

However I get a compile error:

'System.Windows.Controls' was not found. Verify that you are not missing an assembly reference. Also, verify that your project and all referenced assemblies have been built.

What can be the problem?

If you look at the documentation here:

https://learn.microsoft.com/en-us/dotnet/api/system.windows.controls.booleantovisibilityconverter?view=netcore-3.1

It's not in the dll you're using.

Namespace: System.Windows.Controls

Assembly: PresentationFramework.dll

Change the assembly.

    Title="MainWindow" Height="450" Width="800"
    xmlns:controls="clr-namespace:System.Windows.Controls;assembly=PresentationFramework"
    >
<Window.Resources>
    <controls:BooleanToVisibilityConverter x:Key="boolConv"/>
</Window.Resources>
