## ATS metadata

### ATS export

- Type ID: `Aspire.Hosting.EntityFrameworkCore/EFMigrationResource`

## Remarks

The resource inherits from `ApplicationModel.ContainerResource` so it can be published as a container image that runs the migration bundle at deploy time when [EFMigrationResourceBuilderExtensions.PublishAsMigrationBundle(IResourceBuilder<EFMigrationResource>, string?, bool, bool, string?)](/reference/api/csharp/aspire.hosting.entityframeworkcore/efmigrationresourcebuilderextensions/methods.md#publishasmigrationbundle-iresourcebuilder-efmigrationresource-string-bool-bool-string) is called with `publishContainer: true`.

- [EFMigrationResource(string, ProjectResource, string?)](/reference/api/csharp/aspire.hosting.entityframeworkcore/efmigrationresource/constructors.md#constructor-string-projectresource-string) -- Represents an EF Core migration resource associated with a project.
