Microsoft addresses migrations at runtime, here: https://docs.microsoft.com/en-us/ef/core/managing-schemas/migrations/?tabs=vs#apply-migrations-at-runtime

For example, you can do this in Program.cs: (tested working in .NET 5.0 preview)

public static void Main(string[] args)
{
    var host = CreateHostBuilder(args).Build();

    MigrateDatabase(host);

    host.Run();
}

private static void MigrateDatabase(IHost host)
{
    using var scope = host.Services.CreateScope();
    var services = scope.ServiceProvider;

    try
    {
        var context = services.GetRequiredService();
        context.Database.Migrate();
    }
    catch (Exception ex)
    {
        var logger = services.GetRequiredService>();
        logger.LogError(ex, "An error occurred creating the DB.");
    }
}
