title: Validation 30000 No Type Specified for the Decimal Column
body: <p>What's the best way of specifying a decimal precision without using attributes.
  I just need to set it in one place for all decimal's in my Data.Models. Its tedious specifying attributes for every decimal.</p>
  <pre><code>public class Customer
  {
      public int customerId { get; set; }
  
      [Column(TypeName = &quot;decimal(18,2)&quot;)]
      public decimal AvailableAmount { get; set; }
  }
  </code></pre>
