Examples of spatial types and linq2db

I’ve spend quite some time trying to figure out how to use linq2db in combination with sql server spatial types. I’m in the need of an example how to achieve this. I’ve just upgraded from an old version of linq2db (1.0.6)

POCO:

[Table(Name = "[MyTable]")] 
public class MyTable
{
       // other properties

        [Column(Name ="HomeLocation"), Nullable]
        public SqlGeography HomeLocation { get; set; }
}

Fetching data:

using (var db = new MyDatabase())
{
      var query = from o in db.MyClasses
      select o;
      return query.ToList();
}

Generated query seems allright!

-- MyDatabaseContext SqlServer.2012
SELECT
	-- other properties are ok
	[o].[HomeLocation]
FROM
	[MyTable] [o]

Exception is thrown: Can't create 'MyDatabase.sys.geography' type or '' specific type for HomeLocation.

Glad to hear! I will reopen it as we still need to update documentation on our side
