❔ How to map dateonly and timeonly?

Getting this error when trying to do a migration:

The property 'UserData.CreatedDate' could not be mapped because it is of type 'DateOnly', which is not a supported primitive type or a valid entity type. Either explicitly map this property, or ignore it using the '[NotMapped]' attribute or by using 'EntityTypeBuilder.Ignore' in 'OnModelCreating'.

Which db provider are you using? Independent from the provider tho, you can use

builder
  .Entity<YourEntity>()
  .Property(x => x.TheProperty)
  .HasConversion<ValueConverter>()

builder
  .Entity<YourEntity>()
  .Property(x => x.TheProperty)
  .HasConversion<ValueConverter>()

with a custom ValueConverter<T1, T2>.
