This walkthrough will use Model First to create a new database, but the EF Designer can also be used with the Database First workflow to map to an existing database. Spatial type support was introduced in Entity Framework 5. Note that to use the new features like spatial type, enums, and Table-valued functions, you must target .NET Framework 4.5.

In Entity Framework 5, there are two main spatial data types: geography and geometry. The geography data type stores ellipsoidal data (for example, GPS latitude and longitude coordinates). The geometry data type represents a Euclidean (flat) coordinate system.

Oct 31, 2013 · One of the latest features added in Entity framework 5.0 is its support for Spatial data type. Entity Framework supports working with spatial data through the DbGeography or DbGeometry classes. Spatial Data type is used to store the location data. Location can be points on earth or any geometric shapes like polygon, curve, etc.

The geography type represents data in a round-earth coordinate system and geometry represent data in a Euclidean (flat) coordinate system. Starting with version EF 5.0, it includes special data types in the System.Data.Entity.Spatial namespace: DbGeography for geography data type and DbGeometry for geometry data type in the SQL Server.

Spatial data type support will happen post initial RTM of EF Core (i.e. after the 7.0.0 release). This is purely due to how much work we can achieve between now and RTM and not because we think this scenario is unimportant.
