    As error says

    Someone added already added an object Currency in DB

    Seems there is a problem in migration process.

    You can try following solution if they helps.

    Run add-migration command in "Package Manager Console":

    Add-Migration First -IgnoreChanges

    do some changes, and then update database from "Initial" file:

    Update-Database -verbose

    If you are working on a Team Project. I will suggest you to set AutomaticMigrationsEnabled to false

    AutomaticMigrationsEnabled = false;

    It will ensure unpredictable migrations and make sure that every developer on the team works with the same data base structure.

    You can also try

    Update-Database -Script for update a database manually. And you can exclude 'Currency' from resulting script
