How to use a usercontrol from another project in the same solution

Question

I have 2 projets in a visual studio solution:

• Text Adventure Game
• Text Adventure Maker

The project "Text adventure Maker" have a userControl. I want to use this userControl directly in the "Text Adventure Game" project.

To do that, I added the reference of the "Text Adventure Maker" project to the "Text Adventure Game" project using visual studio :

Then I tried to call that reference by using this line on my mainWindow WPF :

<Window x:Class="Text_Adventure_Game.GameWindow"
    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:local2="clr-namespace:Text_adventure_maker;assembly=Text adventure maker" <!-- THIS LINE -->

    xmlns:local="clr-namespace:Text_Adventure_Game.Utilities.CustomUIElement"

Sadly, this give me an error :

"The uri "Textadventuremaker" cannot be found. Make sure that no assembly reference is missing".

So, what should I do to not have this error anymore so I can use my other usercontrol in the other project to this one? thanks [1]: https://i.stack.imgur.com/eWUoe.png
