Using the latest pre-release version of EntityFramework 7 (v7.0.0-rc1-final), I have tried to use the Add-Migration PowerShell command through the Package Manager Console in Visual Studio; I have tried to add migrations to my DAL.

With a folder structure that looks something like:

-Project
  -DAL
    -Context.cs

I have tried variations of the following command:

Add-Migration Initial -OutputDir DAL\Migrations -Context ContextClassName

Including, but not limited to:

Add-Migration Initial -OutputDir DAL\Migrations -Context Project.Namespace.DAL.ContextClassName

Add-Migration Initial -OutputDir DAL\Migrations -Context DAL\Context.cs

To no avail...

The package for the tools is installed like so:

Install-Package Microsoft.EntityFrameworkCore.Tools -Pre

The docs are less than helpful and Get-Help Add-Migration -Examples and -Full, -Detailed etc. give you nothing relating to the expected format of the -Context parameter.

What is the correct format?

You're using the wrong EF7 package! As per the announcement, there's no longer an Entity Framework 7 but only EntityFrameworkCore.

As per your linked documentation and specifically following the documentation section for Full DotNet You need to reference Microsoft.EntityFrameworkCore.* and not EntityFramework.* (for EF7)

Following the instructions of above page and issuing:

Add-Migration -OutputDir DAL\Migrations -Context ContextClassName

I have no issue getting the migration sorted.

  • Thank you. You helped me resolved an issue by running `PM> Add-Migration MyFirstMigration -Context BloggingContext` for a Microsoft example of ASP.NET Core 1.0 project on VS2015- Update 3` released on June 27, 2016. – nam Jul 02 '16 at 17:38
