When I set a project to publish on save sometimes I get an error in output pane that says ">Publish can't start. No publish profile selected." This is not true because I certainly have a profile. Sometimes it just starts publishing ALL of the files. I never tell it to do this. Also now when I right click on a file in solution explorer there is no option to publish that file. Seems like everything worked last week.
This seems like a bug; this functionality wasn't supposed to be changed.
For publishing specific files or folders, you can now use the new remote explorer window.
We'll take a look at the publish-on-save functionality;
