I'm upgrading an application from ASP.NET Core 3.1 to 6.0. Reading the migration documents, I found this:

https://docs.microsoft.com/en-us/ef/core/what-is-new/ef-core-5.0/breaking-changes#getcolumnname-obsolete

And I'm using that method here:

	public class MainDbContext : DbContext
	{
		protected override void OnModelCreating(ModelBuilder modelBuilder)
		{
			base.OnModelCreating(modelBuilder);
			// ...

			// Map JSON string properties to the native type jsonb.
			foreach (var entity in modelBuilder.Model.GetEntityTypes())
			{
				foreach (var property in entity.GetProperties())
				{
					if (property.GetColumnName().EndsWith("Json") &&
						property.ClrType == typeof(string))
					{
						property.SetColumnType("jsonb");
					}
				}
			}
		}
	}

This doesn't compile anymore. The migration document has a code sample that doesn't look right to me. I don't want to look up anything in "Users" here but I need the column of a table. (Are there other columns, too?!) The documentation of the method itself is not helpful as it does not explain what I should pass as parameter.

How can I make that code work again with the current EF version? I want that method back and I don't understand why it was removed. It has always worked perfectly for me. This change is not an improvement for me.
