How do I specify the maximum column length of a field using entity framework code first

Question

Is there an attribute I can use when creating a table ? I tried [StringLength] but it seems to be ignored.

 public class EntityRegister
 {
     public int Id { get; set; }
     [StringLength(450)]
     public string Name { get; set; }
 }

Solution

alternatively, you can manually do it on Fluent API

use HasMaxLength(450)

• Configuring Properties and Types with the Fluent API
  • EF 6
  • EF Core

or if you want Data Annotation, use MaxLength and MinLength attributes

public class EntityRegister
{
    public int Id { get; set; }
    [MaxLength(450)]
    public string Name { get; set; }
}

• Code First Data Annotations
