Can WPF DocumentViewer be used to view XPS documents with .NET 3.5?

I want to display a XPS document in a WinForms application using the WPF DocumentViewer component in an ElementHost.

I've typed the correct lines to load the XPS file into the Documentviewer:

XpsDocument xpsDoc = new XpsDocument(xpsfile, System.IO.FileAccess.Read);
xpsView.Document = xpsDoc.GetFixedDocumentSequence();

The problem is that I'm getting the following exception and callstack:

A first chance exception of type 'System.TypeLoadException' occurred in mscorlib.dll

Additional information: Could not load type 'Syst开发者_运维问答em.Runtime.Versioning.TargetFrameworkAttribute' from assembly 'mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.

Could this be related to the Net 4.0 requeriment? I need to target 3.5 for this project. XPS ReachFramework is available since 3.0 but I don't know where to look.

THanks in advance.
