title: How to add a new table with EF core
body: <p>I have an existing database already that was created when i added Identity to the project. Now i wanna add more tables to the database and can't figure out how.</p>
  
  <p>I have created a model for it: </p>
  
  <pre><code>public class Match
  {
      public Guid ID { get; set; }
      public string HomeTeam { get; set; }
      public string AwayTeam { get; set; }
      public int FullTimeScore { get; set; }
      public DateTime MatchStart { get; set; }  
      public int PrizePool { get; set; }
  }
  </code></pre>
  
  <p>My context:</p>
  
  <pre><code>public class DynamicBettingUserContext : IdentityDbContext&lt;IdentityUser&gt;
  {
      public DynamicBettingUserContext(DbContextOptions&lt;DynamicBettingUserContext&gt; options)
          : base(options)
      {
      }
  
      protected override void OnModelCreating(ModelBuilder builder)
      {
          base.OnModelCreating(builder);
          // Customize the ASP.NET Identity model and override the defaults if needed.
          // For example, you can rename the ASP.NET Identity table names and more.
          // Add your customizations after calling base.OnModelCreating(builder);
      }
  }
  </code></pre>
  
  <p>What's the next steps?</p>
