To add EntityFrameworkCore to your project, update the project.json file (add new lines into the dependencies and tools sections):
"dependencies": {
...
"Microsoft.EntityFrameworkCore.SqlServer": "1.0.0",
"Microsoft.EntityFrameworkCore.SqlServer.Design": "1.0.0",
"Microsoft.EntityFrameworkCore.Design": {
"version": "1.0.0",
"type": "build"
},
},
"tools": {
...
"Microsoft.EntityFrameworkCore.Tools": "1.0.0-preview2-final"
}
Don't forget to run dotnet restore to actually download these packages from the internet.
If you are using an RDBMS other than Microsoft SQLServer - replace Microsoft.EntityFrameworkCore.SqlServer with the correct version (Microsoft.EntityFrameworkCore.Sqlite, Npgsql.EntityFrameworkCore.PostgreSQL or other - consult your RDBMS documentation for the recommended package).
