Data Binding in WPF

Coming from a Flex background I am curious to know if its possible to data bind to local objects in memory in WPF.

The main reason for this is for implementing Model View Controller, where say inside of a WPF Control ill have a reference to the Model and on the actual WPF control certain visual elements properties need to be databound to properties inside the reference model object.  Is this possible in WPF?  The Microsoft tutorials  are not very clear about how to go about such a basic task, in Flex its simple, if it was a text box for example

text={model.textField}

and thats it! but wpf seems alot more complicated and I have not seen an example of direct static reference binding

in  WPF you could use text="{Binding myField}" where myField is a public property of the object  containg the data you want mapped.  
You can set the Model or object  by using the DataContext property in your c# (or vb) code ie; MyXamlForm.DataContext = MyModel
Once that is set MyXamlForm will be able to bind to any public properties in your object.

Also - the public property you map to should also be a Dependency Property. You can use the Visual Studio code snippet (propd) to set up the syntax and save you from typing all the code that goes with that. This also means your class should implement the DependencyObject class.

Thanks for the credit.
I'm afraid I made the answer look more confusing than it is. In its simplest form you just bind properties in the wpf form to a public property in your class/object. From your flex example it looked very similar to me.

The Xaml looks like:
<TextBlock Text="{Binding weekday}" Margin="2,0" />

You can also bind to arrays, collections and lists. it's actually very flexable. no pun intended.
