Answer 1

App2 needs to "check" the table1 for new data and reload it. You can perform a select on table 1 and look for new rows by ID for example.

Answer 2

It simple as it looks .

Case 1 : when there is a change in data in table . upon you access to the content ON-LOAD or Post you will get updated data automatically .

Case 2 : When there are changes in columns or table schema etc . you just open edmx after than on the panel where all tables dispalyed Right click and Click Update option and then build which will auto generate entities automatically .
