Note: These connection strings can be managed from the Azure Web portal for Azure apps.Īn MVC Web application can still use capabilities such as encrypted connection strings or read from Key Vault. Pass the web.config connection string name.Whereas, the EFMigrationManagerUI plug-in reads the connection string in either of the following ways: No need to share the connection string with different team members to deploy the database migrations in various builds(QA/uat/stage/prod). There’s no need to store the SQL connection string in multiple places like Web.config and VSTS build/release configurations for deployment purposes.This user interface is helpful to development team members for managing migrations even when some of the development team member(s) have no expertise on Entity Framework code-first. For instance, some team members have expertise in client-side technologies. Not everyone in the development team members have expertise on Entity Framework code-first migrations or the Package Manager Console to update/rollback migrations.Upon successful deployment or swap of Stage/Production slots in Azure, navigation to the Web site will auto redirect to the database deployment page for admin users. It’s easy to integrate database deployments with administrative processes.With this tool, upon database restore, administrators can navigate to the Web application and publish the pending migrations with the simple user interface, without waiting for a developer to deploy the database migrations.Upon database restores, there is a chance that corresponding Web applications could break due to mismatched database context. As part of this process, QA/UAT/Stage databases will be restored periodically with production backups. It is always helpful to test the Web application with a production database copy.This user interface is helpful for visually managing migrations, with a quick indication of pending migrations to be applied to the database. Easy to integrate with ASP.NET MVC Web applications with Windows and forms authentication.With a simple user interface, it’s easy to manage all pending migrations or roll back to a previous migration.This package source code is hosted in a GitHub repository. This is the URL for the EFMigrationsManagerUI NuGet package. This plug-in is hosted at under the MIT license, which will be very helpful to download and integrate in other ASP.NET MVC applications. To handle the preceding cases, an open-source plug-in called EFMigrationsManagerUI was created to manage Entity Framework migrations through the user interface. If the Entity Framework migrations are not in sync with the database the application will throw a context change error, the Web application will not run in the local/development machine, and the UI designer (take an UI designer, as an example) is unable to work on the Web site until another team member(s) can help the designer to deploy the database. For instance, some of the team members are experts in UI design or client-side technologies like Angular JS, jQuery, and so forth. Not everyone on a development team is an expert on managing EF.Pending migrations needs to apply to the database. There is no simple built-in user interface to manage migrations such as these: To deploy/rollback the Entity Framework migrations to a database, developers need to know about the Entity Framework commands like update-database. Entity Framework code first provides an abundance of capabilities and advantages for Microsoft developers (I am not covering the Entity Framework advantages in this article). These days, Entity Framework is most popular ORM in Microsoft technologies. In this article, I’ll describe the user interface to deploy and manage Entity Framework migrations for ASP.NET MVC applications. Read on to learn how EFMigrationsManagerUI can help your EF migration workflow. Included exception-handling features ensure that users are given a user-friendly maintenance message if migrations need to be applied, instead of the default ASP.NET error pages. The EFMigrationsManagerUI NuGet package provides an easy way to understand a user interface that your deployment and administrative team can use to verify and apply pending migrations directly from your site. Also, troubleshooting EF issues, such as context change exceptions, can require multiple steps. Although Entity Framework (EF) code first provides good tooling for developers to apply migrations from the command line or Package Manager Console, there is no built-in way to monitor migration status directly from an ASP.NET Web site.
