Question

Okay so I have encountered a frustrating issue with namespaces.

I am currently using

xmlns:local="clr-namespace:Company.ecommerce.WPF"

And it seems to be able to get everything else fine from here apart from one class.

public class StringToVisibilityConverter

This class is inside >WPF>ProductFeatures>FeatureSet.XAML.CS and I am trying to use,

<local:StringToVisibilityConverter x:Key="StringToVis"/>

inside my FeatureSet.xaml

however no matter how I try and set the namespace it comes back with:

The tag 'StringToVisibilityConverter' does not exist in XML namespace 'clr-
namespace:Company.ecommerce.WPF'.

Answer 1

Check namespace of you class

public class StringToVisibilityConverter

It should be same everywhere.

When we create a usercontrol in a folder, the namespace it gets created in is parentnamespace.foldername.

From the usercontrol UI and codebehind remove .FolderName and rebuild the project.It will work.

OR

Include the new namespace with my tag like

xmlns:my = ".......

and use it like

<my:StringToVisibilityConverter x:Key="StringToVis"/>
