How can I inherit from my custom made page?



Example:

I have a page baseclass in my 1st assembly:

<Page x:Class="Common.WinFX.Pages.DetailPage"

xmlns="http://schemas.microsoft.com/winfx/avalon/2005"

xmlns:x="http://schemas.microsoft.com/winfx/xaml/2005"

Title="DetailPage"

>

<Grid>

<Label>Test</Label>

</Grid>

</Page>



How can I inherit a new page (in another assembly)?

If I do this:

<DetailPage x:Class="Contact.WinFX.ContactPersonDetail"

xmlns="http://schemas.microsoft.com/winfx/avalon/2005"

xmlns:x="http://schemas.microsoft.com/winfx/xaml/2005"

Title="ContactPersonDetail"

>

<Grid>



</Grid>

</DetailPage>



I get an error stating that the DetailPage is an unknown tag.

I'm "using" the 1st assembly. Do I need to make some xml tag?
