The type name 'GUI' does not exist in the type 'MyProject'

I'm pulling my hair out and can't figure out what's the problem.

Inside MyProject.GUI there are three elements: Form, Keyboard and SelectWrapper

There we go (no .xaml, just .cs)

namespace MyProject.GUI
{
    public class SelectWrapper : Grid
    ...

and keyboard cs

namespace MyProject.GUI
{
   public partial class Keyboard : UserControl
   {
   ...

and keyboard xaml

<UserControl 
         x:Class="MyProject.GUI.Keyboard"
         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

and form .cs

namespace MyProject.GUI
{
    public partial class Form : Window
    ...

and form XAML

 <Window      
         x:Class="MyProject.GUI.Form"
         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
         xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
         xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
         xmlns:gui="clr-namespace:MyProject.GUI"

      ...

      <gui:Keyboard
      <gui:SelectWrapper

And the compiler (as well as the designer) complains:

The type name 'GUI' does not exist in the type 'MyProject'

The type name 'GUI' does not exist in the type 'MyProject'

The name "SelectWrapper" does not exist in the namespace "clr-namespace:MyProject.GUI".

It doesn't complain about the keyboard tho (only the Form). Please assist.

If the compiler says MyProject is a type, I would start with the assumption that there's a type somewhere by that name. I was able to reproduce this by defining a class named MyProject in the MyProject.GUI namespace:

namespace MyProject.GUI
{
    public partial class Form : Window
    {
        public Form()
        { ... }
    }

    public class MyProject
    {
    }

    public class SelectWrapper
    {
    }
}

XAML

<Window 
    x:Class="MyProject.GUI.Form"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    xmlns:gui="clr-namespace:MyProject.GUI"
    mc:Ignorable="d"
    Title="MainWindow" Height="350" Width="525">
    <Window.Resources>
        <gui:SelectWrapper
            x:Key="test"
            />
    </Window.Resources>

Error CS0426 The type name 'GUI' does not exist in the type 'MyProject'
Error CS0426 The type name 'GUI' does not exist in the type 'MyProject'
Error The name "SelectWrapper" does not exist in the namespace "clr-namespace:MyProject.GUI".

So I would look for a class by that name in the project, or elsewhere in the solution.

The Keyboard class resides in another namespace, namely InvoiceFlow.GUI, doesn't it?

<Window      
     x:Class="MyProject.GUI.Form"
     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
     xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
     xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
     xmlns:gui="clr-namespace:MyProject.GUI"
 xmlns:kbd="clr-namespace:InvoiceFlow.GUI"
 ...
  <kbd:Keyboard
  <gui:SelectWrapper

You need to make sure that there are no other compile errors as well for you to be able to build.
