I have tried to move a form from one solution to other, although it doesn’t seem to work. When selecting the ‘Move Form’, a dialog pops up, I select a solution to move the form into, click ‘OK’ and nothing happens.
I am thinking the “Move Form” works to move form in between the Active solution & the Modules attached(If I am not wrongly interpreting). The Move Form dialog(comes up after selecting the “Move Form” option) only shows the destination solution as the attached Modules & active solution. If this is the case, then It is working okay here(4.1.0 rc2 - build 647).
Note that you can use the package explorer view (or any file system view) to move/duplicate assets around between solutions.
In some cases you just need to move the directory or .obj file (relationships, value lists). In other cases you need to move the directory plus the associated .obj file (forms and media).
