Entity Framework creates mad bin tables? Why?

These "tables" are actually old dropped tables.

By default Oracle does not really drop a table when you run DROP TABLE but moves it to the "recycle bin".

You can either disable the recycle bin or simply purge it to get rid of the old ones:

To permanently delete thos tables use:

purge recyclebin;

You can disable the usage of the recycle bin for your session using:

ALTER SESSION SET recyclebin = OFF;
