What is the location of the "__MigrationHistory" table created by the Conect of ADO.Net drivers
Steps to Reproduce
Clarifying Information
Referencing the Connect for ADO.Net documentation:
"Using Multiple Entity Framework Versions Against the Same Database. A single database can use multiple versions of the Microsoft ADO.NET Entity Framework: 5.0 (EF5) and 6.0 (EF6). However, when you switch between EF5 and EF6 applications against the same database, you will receive an error when you try saving to the database. The error occurs due to the difference between the structure of the "__MigrationHistory" table used by EF5 and EF6. To use EF5 and EF6 applications against the same database without any errors, run the following command in the database:
drop table "__MigrationHistory" ".

Where do you find the "__MigrationHistory" table?

The Connect for ADO.Net provider creates the "__MigrationHistory" table in the database being used by the application.

The “__MigrationHistory” table will only be created if Code First or Code First with Migrations workflows are used.

Note if you are using Database First or Model First workflows, the “__MigrationHistory” will not be created on the back-end.
