Saving changes in script tasks/components is a three step process: Build/Save/Ok.

1.) In VSTA, change the .NET framework and then Build the solution.

2.) Save the solution and close VSTA.

3.) When you are back to the Script Transformation Editor, click OK. If you click cancel, all of your changes will be eliminated and you will have to redo everything.
