Question

I am trying to follow this radiobutton tutorial

I created a class called EnumMatchToBooleanConverter and it is in the top level of my wpf project. It says to place the inside a window.resources like this:

<Window.Resources>
  <EnumMatchToBooleanConverter x:Key="enumConverter" />
</Window.Resources>

I am using it in a usercontrol so I have placed it inside a stackpanel instead:

<StackPanel.Resources>
  <EnumMatchToBooleanConverter x:Key="enumConverter" />
</StackPanel.Resources>

I have Microsoft Visual Studio Ultimate 2012 and it gives me an error:

EnumMatchToBooleanConverter is not supported in a Windows Presentation Foundation (WPF) project.

Any ideas as to what I am doing wrong? Am I not allowed to place it inside a stackpanel.resources?

I just tried placing it inside a grid.resources

<Grid.Resources>
  <EnumMatchToBooleanConverter x:Key="enumConverter" />
</Grid.Resources>

and it says

The type ‘EnumMatchToBooleanConverter’ was not found. Verify that you are not missing an assembly reference and that all referenced assemblies have been built.

Well it is in the same namespace as the rest of my project, so I’m unsure why it isn’t finding it.

Answer 1

Change

<EnumMatchToBooleanConverter x:Key="enumConverter" />

for

<local:EnumMatchToBooleanConverter x:Key="enumConverter" />

All non-built-in classes you reference in XAML must be prefixed by their corresponding xmlns prefix.
