ef-migrations

With Entity Framework 6 and a working PostgreSQL database plus connection I am trying to run the Add-Migration and Update-Database commands and create an update script via a console app. It is possible to run the commands from a console since it are "just thin wrapper around an API", see this SO-answer for the example I used. The creation of migrations work, three regular files are created, namely: Initial.cs Initial.Designer.cs Initial.resx Here's the console app that does not work for Update-Database . public static void Main() { // Specify the name of the database migration // Note: make

I'm using Entity Framework Code First approach in my project. I have a problem with database migration. Now I have the entity public class Event { public int Id { get; set; } public string Title { get; set; } public string City { get; set; } } I have already have data in my existing DataBase. Now I want to extend City property, like this public class Event { public int Id { get; set; } public string Title { get; set; } public virtual Location Location { get; set; } } so, City become to Location with many properties. public partial class Location { public int Id { get; set; } public string

​In our Web API application, Continuous deployment need a following scenario. User will check in code in VS, Code will get automatically build, Code will be Published, Code will be deployed. But If we are using Entity Framework Code First approach, How can we update database without manual commands (Add-Migration/Update Database)and make database up to date with that check-in. You can try to run Add-Migration/Update Database commands in the build/deploy process. Assume you are using vNext build, Add a " Nuget Installer " task in your build definition first to restore the Entity Framework

I upgraded a project to Entity Framework 4.3 and enabled migrations on the project. However, I get this error when running the Update-Database command: Cannot scaffold the next migration because the target database was created with a version of Code First earlier than EF 4.3 and does not contain the migrations history table. To start using migrations against this database, ensure the current model is compatible with the target database and execute the migrations Update process. (In Visual Studio you can use the Update-Database command from Package Manager Console to execute the migrations

I have a project with the CodeFirst database (Entity Framework 6) and two migration steps. Database is updated automatically by using this code in Application_Start in Global.asax: Database.SetInitializer( new MigrateDatabaseToLatestVersion<MyDBEntities, MyNamespace.Configuration>()); First migration step is creating the tables: CreateTable( "dbo.GalleryAlbum", c => new { Id = c.Int(nullable: false), //other columns..... }) .PrimaryKey(t => t.Id); CreateTable( "dbo.GalleryPics", c => new { Id = c.Int(nullable: false), //other columns..... }) .PrimaryKey(t => t.Id) .ForeignKey("dbo.GalleryAlbum

Using the Entity Framework 5.0, I am attempting to manually migrate my code-first database during my MVC site's start up routine. To do this, I first create a DbContext instance and then run the following code: var migrator = new MigrateDatabaseToLatestVersion<DataContext, Configuration>(); migrator.InitializeDatabase(this.dataContext); I assumed the database associated with the dataContext's connection would be the one migrated. It appears though that this is not the case. Instead, it always tries to migrate a database on a local SQLExpress instance. There is an overload to the
