New Post: FileNotFoundException in XAML designer (Visual Studio 2012/2013)

I am also encountering a similar issue. I've just installed VS2013 Ultimate and upgraded all projects to this with .NET 4.5.1 runtime specified. When I create a simple standalone project things work fine, but when interacting with my existing projects I get the errors.

I've tried both adding this into an existing project, and as a separate project in my solution. In both cases I get the error raised at the XAML line: <oxy:Plot Model="{Binding ViewModel.MainPlotModel}"/>.

My VS info is:
Microsoft Visual Studio Ultimate 2013
Version 12.0.21005.1 REL
Microsoft .NET Framework
Version 4.5.50938
Installed Version: Ultimate


Here are the exception details:
