Entity Framework applying too many migrations

Question

We use Entity Framework 6.0 and added a new table using Code First. As usual, we created the EntityMap and added the entity and the map to the context. When we try to upgrade the database using the package manager console command "update-database -script", EF wants to apply all migrations (including the ones that are already in the __MigrationHistory table).

Has anyone experienced the same issue and knows how to solve it?

Thanks in advance

We found the issue thanks to the comment of @Amy... When adding the Parameter -Verbose, it became clear that the migrations will be applied to a (new) localDb. We didn't specify the -StartUpProjectName and assumed, it will be the selected default Project. After the -StartUpProjectName was set, everything worked fine :-)
