XAML Syntax to Declare Instance of Private Class

[Jules Winfield]

I'm designing a WPF user control. Within the C# portion of the class is a
private conversion class:

private class MyConverter:IValueConverter{
....
}

Within the XAML portion of the class I'd like to create an instance of this
class:

<UserControl.Resources>
<ResourceDictionary>
....
<aia:MyConverter x:Key="Cvt"/>
</ResourceDictionary>
</UserControl.Resources>

(The namespace "aia", referenced above, is properly defined in myXAML class
definition)

The problem is that somehow my declaration syntax is wrong. I can't seem to
declare an instance of my private MyConverter class in XAML. If I move
MyConverter out of the user control and make it it's own top-level class in
the "aia" namespace, everything compiles properly. So how do I declare an
instance of a private class within XAML?

Hi Jules,

An XAML tag must be the top-level class in a namespace. That's to say, WPF
doesn't support the function you want so far.

The only workaround is to move the MyConverter class out of the user
control and make it a top-level class in the namespace.

If you have any concern, please feel free to let me know.

Sincerely,
Linda Liu
