Type or namespace name 'Ui' does not exist in the namespace when I set a name to a wpf-ui component in xaml

[bryonac99]

Describe the bug

Hi, I'm using wpf-ui on my wpf app. It's working, but when I write x:name or name to a component in the xaml it gives me the following error:
The type or namespace name 'Ui' does not exist in the namespace 'Client.Wpf' (are you missing an assembly reference?)
If I cancel the name or x:name the error will go away.

To Reproduce

Set name or x:name to a wpf-ui component.

Expected behavior

x:name in wpf-ui component working

It looks like there is something else in your project whose namespace has *.Client.Wpf.*. Try global::Wpf.Ui or consider changing some names or using's in your files.

How do I set global:Wpf.Ui namespce in xaml? It's working on codebehind, but I need it in xaml for x:Name.

To understand the error, it would be best if you sent the entire code that would allow to reproduce the error.

In xaml:
xmlns:ui="http://schemas.lepo.co/wpfui/2022/xaml"
<ui:Button
x:Name="addDeviceBtn"
HorizontalAlignment="Left"
Appearance="Success"
Command="{Binding AddDeviceCommand}"
Content="Add Device"
Cursor="Hand"
Icon="{ui:SymbolIcon Add24}" />
Error CS0234: The type or namespace name 'Ui' does not exist in the namespace 'MyApp.App.Wpf' (are you missing an assembly reference?)
If I remove x:Name the error goes away

Would be better full .csproj in zip or repo

Unfortunately I can't share this project..

You don't have to send the project, just the minimal code that causes the error

I ran into this now, with a project being named xyz.Client.Wpf - and also xyz.Client.UI.Wpf - I renamed the project and root namespaces to xyz.Client.Windows (getting rid of the Client and Wpf parts, and it worked.

Try renaming the project so it doesn't end/have .Wpf, same for all the namespaces
