How to use Ribbon Buttons to execute code?

So far I have managed to create a ribbon with several buttons by following this tutorial.

Now I want to make the buttons actually do stuff! I found this example which shows how to execute already existing method. However if I do: Command="myCustomClass.myCustomMethod" and use

Class myCustomClass
    Public Sub myCustomMethod()
        'do stuff
    End Sub
End Class

I get the error myCustomClass is not supported in a Windows Presentation Foundation (WPF) project.

I also noticed this this post from the same post. After converting the code to VB.NET:

Public Class MyCommand
    Implements ICommand
    Public Sub Execute(parameter As Object) Implements ICommand.Execute
        Dim hello As String = TryCast(parameter, String)
        MsgBox(hello)
    End Sub

    Public Function CanExecute(parameter As Object) As Boolean Implements ICommand.CanExecute
        Return True
    End Function

    Public Event CanExecuteChanged As EventHandler Implements ICommand.CanExecuteChanged
End Class

and adding the references to the <Window x:Class="MainWindow" ... element:

<Window.Resources>
    <local:MyCommand x:Key="mycmd"/>
</Window.Resources>

I get the following error: The name 'MyCommand' does not exist in the namespace "clr-namespace:RibbonSample".

I'm at a complete loss as to what I need to do to implement these buttons. Would it be possible to get any full ribbon samples using the same framework, with which I can learn from? I assume the solution to this should be really simple.

Rebuild your project.

The WPF designer loads classes from your project's compiled assembly (so that it can actually execute your code).

If you add a new class, it will give you errors until you rebuild your project so the assembly includes that class.
