I created a custom control and then attempted to use it in my main xaml file. I created a reference to the custom control using the xml namespace declaration. The xaml file looks like this:

Code:

<Window x:Class="WpfApplication1.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="clr-namespace:WpfApplication1;assembly=WpfApplication1"
    Title="Window1" Height="400" Width="400">
    <Grid>
        
    </Grid>
</Window>

The error reads as this:

Code:

Assembly 'WpfApplication1' was not found.
Verify that you are not missing an assembly reference.
Also, verify that your project and all referenced assemblies have been built.

Just to test, I created a new WPF project and added that xmlns declaration, nothing else, and it still gives the same error.



To note: This is Visual C# 2008 running on Win XP SP3. I know this error can be avoided cause I have another project I downloaded as a source reference that uses custom controls and does a similar xmlns declaration and it runs just fine.

Anyone have any ideas?

Did you add a WpfApplication1.dll assembly reference to your project as the
error suggests?

It worked fine in VS2008 Team System. I copied that project and imported it into the express edition and it was fine.

It is kind of a hack. That was before your suggestion. I should not have to reference the assembly since it is in the same assembly.
