In my solution I have 2 project. Let's call them the "editor" and the "player". They both operate on the same file type.
Now in my deployment project, I have set up a new file type ".myext", and defined the command to the primary output of "editor". Then I created an action "Edit". So far so good.
Now I want a second action called "Play" that would invoke the primary output of "player". But the command is tied to the file type. So I could call editor with differing parameters, but not another assembly.
If I just define the type a second time with a different command, VS will give me an error: "There are two or more file types named ...".
I guess I could direct all operations to the same app and start the other one if needed but I'm hoping there is a more direct approach.
