Use user control name without namespace prefix

Lets say I have a user control such as this:

<UserControl
    x:Class="WPFUserControl.MyUserControl" 
    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"
    mc:Ignorable="d" d:DesignHeight="300" d:DesignWidth="300">

    <StackPanel Orientation="Horizontal">
        <TextBox x:Name="txtName" />
        <Button
            x:Name="btnClickMe"
            Content="Greet Me" />
    </StackPanel>

</UserControl>

and a Window like this:

<Window
    x:Class="XAMLUserControl.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:control="clr-namespace:WPFUserControl"
    Title="MainWindow" Height="600" Width="800">

   <Grid>
      <control:MyUserControl/>
   </Grid>

</Window>

Is there a way I can refer to the user control without using the control: prefix?

So, instead of writing

<control:MyUserControl/>

I would use

<MyUserControl/>

You can use the XmlnsDefinitionAttribute to make the namespace containing MyUserControl "belong" to the same xml namespace (something like this : http://schemas.microsoft.com/winfx/2006/xaml/presentation, basically the value assigned to xmlns itself in your UserControl's xaml) as all native wpf components. That should let you use your UserControl without having to use a namespace prefix.

Usage for your example would be in AssemblyInfo.cs, doing [assembly:XmlnsDefinition("http://schemas.microsoft.com/winfx/2006/xaml/presentation", "WPFUserControl")].

The first paramater is the xml namespace that will be used and the second parameter is the c# namespace that contains the things you want to use without prefix in xaml.

You can find more info about how XAML and C# namespaces work together here
