Noobie WPF namespace and converter problem

Question

Hi All, Please forgive the noob question but I'm going round in circles and need answers...

Anyway, I've been looking at this article WPF: How to bind RadioButtons to an enum? but I just can't get the convertor to be recognised within the XAML file.

<Window x:Class="Widget.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:dg="http://schemas.microsoft.com/wpf/2008/toolkit"
    Title="Widget" Height="366" Width="588" WindowStyle="SingleBorderWindow">
    <Window.Resources>
        <EnumBooleanConverter x:Key="enumBooleanConverter" />
    </Window.Resources>
...

I have a seperate file holding the EnumBooleanConverter class but the above reference gives me the following error:

Error 1 The tag 'EnumBooleanConverter' does not exist in XML namespace 'http://schemas.microsoft.com/winfx/2006/xaml/presentation'.

I've tried adding references to the assembly and then appending the tag to the XAML but to no avail.

<Window x:Class="Widget.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:dg="http://schemas.microsoft.com/wpf/2008/toolkit"
    xmlns:local="clr-namespace:Widget;assembly=Widget"
    Title="Widget" Height="366" Width="588" WindowStyle="SingleBorderWindow">
    <Window.Resources>
        <local:EnumBooleanConverter x:Key="enumBooleanConverter" />
    </Window.Resources>
...

Any help would be greatly appreciated.

Answer 1

Make sure EnumBooleanConverter is publicly accessible and it has a public empty constructor.

Answer 2

After much head scratching (and a fair amount of shouting at the screen) I have identified the problem.

It turns out that identifying the namespace shouldn't have the assembly.

I was defining it like this

xmlns:local="clr-namespace:Widget;assembly=Widget"

... But it should have just been like this

xmlns:local="clr-namespace:Widget"
