Entity Framework Core–Storing a string array

Starting from EF Core 2.1, storing a string array becomes possible thanks to the support for value conversions

Here is our Entity:

	public class MyEntity
	{
	public Guid Id{get;set;}
	public string[] Strings { get; set; }
	}

And here is the code we added in the OnModelCreating():

	modelBuilder.Entity<MyEntity>()
	.Id(e=> e.Id)
	.Property(e => e.Strings)
	.HasConversion(
	v => string.Join(',', v),
	v => v.Split(',', StringSplitOptions.RemoveEmptyEntries));
