CreditoImobiliarioBB.Web

All interface are defined here. Has reference to the project CreditoImobiliarioBB.EntityFramework and EF6.
No configuration (we use FluentApi) or migrations is defined here.

CreditoImobiliarioBB.EntityFramework

Here is defined our generic repository and DbContext. All configurations and migrations are implemented here.

CreditoImobiliarioBB.Domain

Our design domain. Here are all our domain classes and interfaces (eg IEntity)

CreditoImobiliarioBB.Repository

Here is the repository implementation. For example EmployeesRepository

Error

When we run our application, the following error occurs:

Migrations is enabled for context 'CreditoImobiliarioContext' but the database does not exist or contains no mapped tables. Use Migrations to create the database and its tables, for example by running the 'Update-Database' command from the Package Manager Console.

Considerations

The database has been created with all configurations aka EntityTypeConfiguration<> via the 'Update-Database'
The error occurs in CreditoImobiliarioBB.EntityFramework project in a generic class Repository

Repository.cs

Error in line return _unitOfWork.Context.Set<T>().Where(expression);

        where T : class, IEntity

    private readonly EFUnitOfWork _unitOfWork;
