I just downloaded the latest v19.1.0680 of the WPF-Controls. I selected to install Code Signed assemblies, and I'm looking at the files in "C:\Program Files (x86)\Actipro Software\WPF-Controls\v19.1.0680\Assemblies\CodeSigned". I haven't checked them all, but the DLLs I used (ActiproSoftware.Docking.Wpf.dll, ActiproSoftware.Editors.Wpf.dll, ActiproSoftware.Shared.Wpf.dll) are NOT signed. When I right click on the DLL and choose "Properties" there is no "Digital Signatures" tab on the properties dialog box like there has been on every previous version.
Can you please update these?
