Entity Framework 6 Code first update Entity with oracle

Question

Migration data first time success. But when I update entity and migration again, it fails:

Unable to generate an explicit migration because the following explicit migrations are pending: [201712281248174_ttt]. Apply the pending explicit migrations before attempting to generate a new explicit migration.

Help! Thank you!

Try these suggestions first and report back if your scenario is different along with relevant code and things you have tried. — Steve Greene

You have to enable automatic migrations in your migration configuration file.

public Configuration()
{
    AutomaticMigrationsEnabled = true;
}

or explicitly run command Update-Database in Package Manager Console.

Thank you! I find the problem is the HasDefaultSchema parameter difference with the User Id in connectionStrings.
