Could not load file Telerik.Windows.PersistenceFramework

[Tommy Z]

I am attempting to use the Persistence Framework to save the state of a GridView into a database when the user clicks a button, using the demos extensively as a guideline.  I am able to register my custom property provider with no problem.  However, when the button is clicked to save the state, I get the following error:

"Could not load file or assembly 'Telerik.Windows.PersistenceFramework, Version=2011.3.1116.1040, etc' or one of its dependencies.  The system cannot find the file specified.'

I've narrowed the problem down to where the PersistenceManager object is being defined.  I have both Telerik.Windows.Controls.dll and Telerik.Windows.PersistenceFramework.dll defined as references in my project, and both are version 2011.3.1116.1040.  All the other telerik dll's being referenced are also the same version.  Is there another file that needs to be referenced that isn't listed in the help documentation?

There must be some conflict with Caliburn and the PersistenceFramework, at least that's my best guess.  I moved the code that does all of the serialization out of the ViewModel and into a separate project and was able to successfully save the grid state.

Hi,

Is there any inner exception that could provide more information on this exception? The PersistenceFramework heavily relies of reflection to get the serialized types and restore objects, which I think might be the cause of this issue.

All the best,
