With dapper, you can't map a SQL Geography column to an EF DbGeography class.

I have table with sql geography column in my SQL database. I have generated entities for my database with EF6. As you know Entitiy Framework generates System.Data.Entity.Spatial.DbGeography for SQL Geography type. I'm using dapper to run queries and map the results into my EF generated entities.

My entity class

public partial class Fix
{
    public Fix()
    {
        this.FixUsers = new HashSet<FixUser>();
    }

    public long FixID { get; set; }
    public long UserID { get; set; }
    public System.Data.Entity.Spatial.DbGeography Position { get; set; }
    public int Radius { get; set; }
    public System.DateTime CreatedDate { get; set; }

    public virtual MemberProfile MemberProfile { get; set; }
    public virtual ICollection<FixUser> FixUsers { get; set; }
}

SQL query which throw an exception

    var fix = SqlConnection.Query<Fix>(@"SELECT TOP(1) 
                                         f.FixID as FixID, 
                                         f.UserID as UserID, 
                                         f.Radius as Radius, 
                                         f.CreatedDate as CreatedDate, 
                                         f.Position as Position
                                         FROM [Fix] f 
                                         WHERE f.FixID = @fixId", new { fixId }).FirstOrDefault();

Here is exception snapshot

I think by default dapper is trying to map to Microsoft.SqlServer.Types.SqlGeography.

Is there any workaround here?

EDITED

Found some solution, created partial class for my entity

public partial class Fix
{
    public string PositionString
    {
        set
        {
            Position = DbGeography.PointFromText(value, 4326);
        }
    }
}

And changed my query

var fix = SqlConnection.Query<Fix>(@"SELECT TOP(1) 
                                     f.FixID as FixID, 
                                     f.UserID as UserID, 
                                     f.Radius as Radius, 
                                     f.CreatedDate as CreatedDate, 
                                     f.Position.ToString() as PositionString
                                     FROM [Fix] f 
                                     WHERE f.FixID = @fixId", new { fixId }).FirstOrDefault();
