Microsoft.Windows.Controls are you missing an assembly reference?

Question

I'm receiving the following error:

Error 26 The type or namespace name 'Controls' does not exist in the namespace 'Microsoft.Windows' (are you missing an assembly reference?)

These two assemblies appear in the .g.cs file:

using Microsoft.Windows.Controls;
using Microsoft.Windows.Controls.Primitives;

When I remove them, the error returns.

Answer 1

Check your XAML code. Probably there will be xmlns pointing Microsoft.Windows.Controls.Primitives or Microsoft.Windows.Controls.
