"I was looking for an easy way to offer in my WPF applications a Textbox able to search for any information and display a list, as users type the search is gone again and data refreshed. I found a good project but it wasn't maintened anymore. So I decided to update it and offer an alternative to it, keeping the original reference mentioned. The package offers two controls: AutoComplete Textbox and AutoComplete Combobox. Both expose a search property which can be implemented as users want. The controls share a base interface to be implemented by users search methods and that's it. As it grew in popularity some bugs were found, new features added and I believe now it is working very well. "
