Hi Robert,I've done this many times and it's always worked. Here are the steps I've taken.
Open the SF Infragistics wrapper Solution (c:\Program Files\Micro Four\StrataFrame source Code\MicroFour strataFrame Infragistics wrapper.sln).
In the solution remove all the Infragistics references and add the corresponding updated ones.
Recompile. You shouldn't have to copy any files. There are build events on the compile that should copy the resulting DLLs to the correct locations.
Open your existing project and delete the old Infragictics references and the updated ones from the GAC.
Close your project and VS.
Restart VS, you'll likely be prompted to update the Toolbox (if not click on the SF menu and selecte Create sf Toolbox). Yoo]u should then be good to go.
