Old namespace still in .g.cs file when changing namespace of a referenced class

I have renamed the namespace of a referenced class and WPF compiler doesn't want to take it into account: it keeps prefixing MyOldNameSpace in .g.cs file:

[System.CodeDom.Compiler.GeneratedCodeAttribute
     ("PresentationBuildTasks", "4.0.0.0")]
public partial class MyClass: 
    MyOldNameSpace.MyReferencedClass, 
    System.Windows.Markup.IComponentConnector {

Why ? How to fix this ? What's this obscure .g.cs file ?

Also check xmlns:local in Application.xaml. This had me going for a while...

In my case removing obj folder fixed the error.

Don't forget to change your Generic.xaml file too,

<ResourceDictionary 
                   xmlns:local="clr-namespace:MyOldNameSpace">
</ResourceDictionary>

Maybe another case is that the build action of your xaml is not "Page" but the other options.

Looks like you didn't change your MyClass.xaml file. There should be something like this on top of it

<MyClass x:Class="MyOldNameSpace.MyReferencedClass"

but should be "MyNewNameSpace.MyReferencedClass"

Close the .g.cs file. You can even delete it.

The g stands for generated, VS generates the wireing up between the code and the Xaml in this partial class.

Clean the solution and rebuild. That should fix it.
