The easiest way to install this plugin is directly from the IDE. This article touches on the new plugin, Entity Framework Core UI for JetBrains Rider, which allows you to execute most dotnet ef commands in a more user-friendly way. However, most commands are called quite often during development, and the lack of a convenient user interface can slow down your development process as a whole. They allow you to perform a full range of tasks, from creating migrations and updating the database to generating SQL scripts from the migration code and creating executable bundles from them. ![]() To work with Entity Framework Core, it is usually a good idea to use its powerful command-line tools – dotnet ef. In this guest blog post, author Andrew Rublyov demonstrates the powerful features behind the Entity Framework Core UI plugin for Rider. In just a few clicks you’ll have produced the necessary EF Core boilerplate code that’s necessary for database operations. ![]() I hope this clarifies on when the “un-apply” and “remove” migration steps should be used.Do you work with Entity Framework Core? Would you like to manage entities right inside your IDE? Then you’re in luck! The Entity Framework Core UI plugin for Rider helps you effectively manage everything you need in EF Core. If a migration is not yet merged to the “main” branch and if the change is still in development, then mostly, you may use the below steps to “un-apply” and “remove” a given migration. If a migration is reviewed and merged already to the “main” branch, then it is better to create another migration to undo the modifications applied by that migration. The question is then – when should we use the steps mentioned in this article ? Generally, if a migration is applied already to the database, and if you want to change anything from that migration, general guidance is to create another migration with intended modifications. A word of caution !įor each and every database modification, EF Core migrations are created and applied to the database. In this article, we are going to have a look at how to “un-apply” and “remove” the EF core migration which has already been applied to the database. After “un-applying”, you may want to remove the generated EF Core migration files and you may want to generate new one. In that case, you may want to un-apply the applied migration. Sometimes, it may happen that you may see some errors in the applied migration. When we work on database design modifications, we generate migrations and we apply them to the database. When the project is in its initial stages, generally there are a lot of modifications as the database design is supposed to be evolving. Many of us have been working on projects which use EF Core for data access. ![]()
