Creating a database with ASP.NET Core RC 2 and Entity Framework core

Yes you can create the database using Entity Framework code first, just like previous versions of ASP.NET. It's a little different though, as you don't use Visual Studio, but rather you open up cmd.exe. Navigate to the project's src folder, then enter the following commands:

dotnet ef migrations add firstMig -c DbContextName

This will create a folder named migrations inside the project, along with an initial migration file and a 'firstMig' file (which is the name of the migration we are creating. These migrations will be used to update the database with the following command:

dotnet ef database update -c DbContextName

I have recently released a blog post, which is a tutorial that goes over step by step how to setup ASP.NET RC2 with Entity Framework code first on a PostgreSQL database. Hope this is helpful!
