SqlCeSHA256 - PlatformNotSupportedException

You read a lot on the internet about this: http://vspug.com/sharedpoints/2010/10/

Not being able to use .NET 4.0 assemblies is understandable when your have a webpart and sharepoint refers to your project.

But when you are referring to SharePoint it should not matter, it works perfectly in 2007, so why not 2010???

I need .NET 4 (discovery and such) in this project, so I need another solution than just downgrading the target framework
