This article explains how to create a class that can handle any kind of data-type conversion by allowing users to register their own conversions and how to make it work both as a global and also as a local solution, so different threads can do different conversions for the same data-types.
<Window x:Class="WpfConfigurableConvertTest.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:App="clr-namespace:WpfConfigurableConvertTest"
        Title="MainWindow" Height="350" Width="525">
    <StackPanel>
        <Label Content="Write something (like Blue, Green or #ff00ff) on one of the text boxes and press tab."/>

        <!-- The binding may look to be in the wrong component but the idea is to show how the binding is really bidirectional.
             Write something (like Blue) in the text box then press tab and you will see that not only the color changes, as
             the text changes too.
        -->
        <TextBox Text="{Binding ElementName=rectangle, Converter={App:Convert}, Path=Background}" />
        <Border Name="rectangle" Background="Red" Height="20" BorderThickness="1" BorderBrush="Black" />
        <TextBox Text="{Binding ElementName=rectangle, Converter={App:Convert}, Path=Background}" />
    </StackPanel>
</Window>

I started to program computers when I was 11 years old, as a hobbyist, programming in AMOS Basic and Blitz Basic for Amiga.
At 12 I had my first try with assembler, but it was too difficult at the time. Then, in the same year, I learned C and, after learning C, I was finally able to learn assembler (for Motorola 680x0).
Not sure, but probably between 12 and 13, I started to learn C++. I always programmed "in an object oriented way", but using function pointers instead of virtual methods.

At 15 I started to learn Pascal at school and to use Delphi. At 16 I started my first internship (using Delphi). At 18 I started to work professionally using C++ and since then I've developed my programming skills as a professional developer in C++ and C#, generally creating libraries that help other developers do their work easier, faster and with less errors.
