Problem

When I run PM> Remove-Migration -context BloggingContext in VS2015 with an ASP.NET Core project using EF Core, I get the following error:
System.InvalidOperationException: The migration '20160703192724_MyFirstMigration' has already been applied to the database. Unapply it and try again. If the migration has been applied to other databases, consider reverting its changes using a new migration.

How can I unapply it? I'm using latest release of ASP.NET Core 1.0, EF Core, and VS2015 Update 3.

Solution

Use:

CLI

> dotnet ef database update

Package Manager Console

PM> Update-Database

Example:

PM> Update-Database MyInitialMigration

Then try to remove last migration.

Removing migration without database update doesn't work because you applied changes to database.

If using PMC, Try:
PM> update-database 0
This will wipe the database and allow you to remove the Migration Snapshot on your Solution
