`Could not load file or assembly 'Microsoft.Windows.Shell` , Prism - C#

Finally I solved this issue by installing Multilingual App Toolkit from here and Add Reference to "Microsoft.Windows.Shell.dll" from the location "C:\Program Files (x86)\Multilingual App Toolkit" or copy the dll to your private assembly folder and refer it.

When you install Microsoft.Windows.Shell.dll from Nuget, it was installing v3.0.1, But the actual expected version was v3.5.41019.1. you ll get this new version from the above path.

Thanks

So after trying everything, I looked for others files in my computer (Microsoft.Windows.Shell.dll) and found newer version, as expected by the Exception (3.5.41019.1) in MicrosoftRibbon for WPF\V3.5 folder.

It is strang,because the latest version of the NuGet package is 3.0.1.

Thanks anyway.
