Question

Can Office load addins targeting different versions of .NET Framework?

Answer 1

A major new feature of the .NET Framework 4 is that it can be loaded "in-process" with the .NET Framework 3.5, .NET Framework 3.0, and .NET Framework 2.0 (all of which use the v2 CLR).

Therefore, to answer your question: Office can now load add-ins that target .NET Framework 4 and add-ins that target .NET Framework 3.5 simultaneously.
