In the /bin/debug folder of my solution I\'ve noticed a slew of what appear to be foreign language folders with names like \"ar\", \"bg\", \"ca\", \"cs\", \
I just struggled with "System.Windows.Interactivity.resources.dll" satellite assemblies in my output folder. I could solve the issue by removing all language folders from "\Program Files\Microsoft SDKs\Expression\Blend.NETFramework\v4.5\Libraries". As discribed here in the MSDN Forum.
