change all string property max length

Question

In EF 6 I can do something like this:

modelBuilder
  .Properties()
  .Where(p => p.PropertyType == typeof(string) && 
              p.GetCustomAtt         


        

Answer 1

I suppose this to be one of the "still lacking" functionalities in EF Core and expect it to be added in some later version.

Until then, the closest I can suggest (for v1.1.0) is as follows:

foreach (var p in modelBuilder.Model
    .GetEntityTypes()
    .SelectMany(t => t.GetProperties())
    .Where(p => p.ClrType == typeof(string) && p.GetMaxLength() == null))
{
    p.SetMaxLength(2000);
}
