I've recently started learning WPF on my own. What is difference when declaring Name vs. x:Name?

Question

For instance, I have this code:

<Grid>
    <Rectangle Name="TheRectangle" Fill="AliceBlue" Height="100" Width="100">            
    </Rectangle>
</Grid>

VS.

<Grid>
    <Rectangle x:Name="TheRectangle" Fill="AliceBlue" Height="100" Width="100">            
    </Rectangle>
</Grid>

Thank you very much for the information. I'm very excited about learning something new like this. :D

There is basically no difference between the two.

The "x:Name" expression is used in XAML to assign a name to an object that will be used to access the object from the code-behind.

Many classes of the framework expose a Name property, which does exactly this. For these classes, both x:Name and the Name property can be used interchangeably.

One minor difference: Name cannot (for some crazy reason) be used in XAML on a control that is declared in the same assembly as the XAML file. In that scenario, you *must* use x:Name instead. – itowlson Nov 11 '09 at 23:56
So it's better for me to be safe and make it a habbit of always using x:Name in the case a framework class doesn't haev a Name property? Regards. – Sergio Tapia Nov 12 '09 at 00:03

You will have a response here

Basically, x:Name is used by WPF to be accessed in Runtime and by XAML to generate fields in the code behind.
