I added a new table to MSSQL via the SQL Server Management Studio tool. Then while still in design view I tried to make another change to the same table. When I hit the save button it says something like “saving changes not permitted because the table needs to be dropped and recreated”.
Looking in the options menu. I found a setting that was causing this problem. To disable this do the following: Tools > Options > Designers > Tables and Designers > Uncheck the Prevent Saving Changes that require table re-creation option.
That fixes it for me.
