Question
Is it possible to have my ASP Core Web API ensure the DB is migrated to the latest migration using EF Core? I know this can be done through the command line, but I want to do it programatically.
Update
Based on the answer from Janshair Khan I came up with this helper class:
using Microsoft.AspNetCore.Builder;
using Microsoft.EntityFrameworkCore;
using Microsoft.Extensions.DependencyInjection;
using MyWebApi.Models;
namespace MyWebApi
{
public static class DataSeeder
{
public static void SeedData(this IApplicationBuilder app)
{
var context = app.ApplicationServices.GetService<MyContext>();
if (!context.Database.EnsureCreated())
context.Database.Migrate();
}
}
}
You can call this from the Configure method in your Startup.cs like this:
app.SeedData();
Accepted Answer
You can use
db.Database.EnsureCreated();
to get your db up to date with your current model. If you want to enable migrations (If subsequent migrations are suspected), then use
db.Database.Migrate();
and put your subsequent migrations over time.

A note from documentation on the call to db.Database.EnsureCreated():
Note that this API does not use migrations to create the database. In addition, the database that is created cannot be later updated using migrations. If you are targeting a relational database and using migrations, you can use the DbContext.Database.Migrate() method to ensure the database is created and all migrations are applied.
You may just want to call db.Database.Migrate().
