Accessing ProgressHelper in a 4.0 application?

We have made extensive use of ProgressHelper in our code to display status's for our users as well as for debugging for the developers.  ProgressHelper is in the Esri.ArcgisExplorer.Application namespace.  In a normal .NET scenario if I set a configuration setting of
      <supportedRuntime version="v4.0.30319" />

Then I can run prior versions under the new framework.  But since the .NET initialization process is bypassed by making this an add-in, the framework never sees this.  So how do I configure ArcMap and the ArcObject environment to recognize that a 2.0 DLL can be loaded in a 4.0 framework to satisfy the rquirements of the 4.0 Framework???
