Run maintenance jobs on Azure SQL

Many users on Azure SQL Server do not realize they have to do their own maintenance on Indexes. This index will slowly become fragmented and the performance will decrease over time. Azure SQL does not have a Job scheduler (agent) like on premise. In this post I’ll describe how to schedule a maintenance job from an ASP.NET Core application.

Add Index with Include Entity Framework Core

When creating indexes with code first migrations in Entity Framework Core you can create an index on a table by adding the following to your DbContext:

protected override void OnModelCreating(ModelBuilder modelBuilder)
{
    base.OnModelCreating(modelBuilder);

    modelBuilder.Entity<table>() 
        .HasIndex(t =&gt; new { t.Column1, t.Column2}); }
