a .NET Standard implementation of the spatial types in Microsoft.SqlServer.Types.

Difference between v1.x and v2.x

The v1.x and v2.x versions are identical and kept in sync. The only difference is the dependency:

  • v1.x : Depends on the legacy System.Data.SqlClient package.
  • v2.x : Depends on updated Microsoft.Data.SqlClient package.


Input parameter

Assigning SqlGeometry or SqlGeography to a command parameter:

   command.Parameters.AddWithValue("@GeographyColumn", mySqlGeography);
   command.Parameters["@GeometryColumn"].UdtTypeName = "Geography";

   command.Parameters.AddWithValue("@GeographyColumn", mySqlGeometry);
   command.Parameters["@GeometryColumn"].UdtTypeName = "Geometry" 

The geometry will automatically be correctly serialized.

Reading geometry and geography

Use the common methods for getting fields of specific types:

   var geom1 = reader.GetValue(geomColumn) as SqlGeometry;
   var geom2 = reader.GetFieldValue<SqlGeometry>(geomColumn);
   var geom3 = SqlGeometry.Deserialize(reader.GetSqlBytes(geomColumn)); //Avoids any potential assembly-redirect issue. See


The spatial operations like intersection, area etc are not included here. You can perform these as part of your query instead and get them returned in a column.
