WPF Toolkit Autocomplete Trouble

Question

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.

Answer 1

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

Answer 2

You need to include that assembly in the project references:

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