I've been starting to get a TypeLoadExceptions on some clients:
Could not load type 'System.Windows.Media.Effects.DropShadowEffect' from assembly 'PresentationCore, Version=220.127.116.11, Culture=neutral, PublicKeyToken=31bf3856ad364e35'.
The problem is repeatable on systems where .NET4.0 is installed but .NET3.5sp1 isn't.
Looking at the GAC on a system with only 3.0 and 4.0 installed, PresentationCore exists and is at version 18.104.22.168.
Am I missing something or is the DropShadowEffect missing from the 4.0 installation?
Please help me solve this!
