I installed the WPF Toolkit using the following NuGet command.

PM> Install-Package WPFToolkit

and then I followed the code in this link to create an autocomplete control without using the designer drag and drop:

WPF: AutoComplete TextBox, ...again

When I ran it, I'm getting this error:

Could not load file or assembly 'System.Windows.Controls.Input.Toolkit, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.

If someone could tell me what I'm missing, that would be very helpful.

You need to include that assembly in the project references:

Right click "References", then "Add reference".

This may be caused by windows security restictions, Try to run VS2010 as Administrator, Uninstall WPF Toolkit using nuget and then reinstall it.
