Entity Framework v5 introduces spatial data types support. They are represented as two new DbGeometry and DbGeography data types from System.Data.Entity.dll in .NET Framework 4.5.
Many our Oracle users use Oracle Spatial functionality in their projects. Before Entity Framework v5 there was no easy way to use Oracle Spatial with Entity Framework, though users of PostgreSQL, PostGIS, and SharpMap could use this cumbersome and limited workaround. This workaround was even harder to use with Oracle Spatial and was almost not used because of numerous limitations.
Now Entity Framework v5 changes the situation, and Devart dotConnect for Oracle provides the best possible support for Entity Framework Spatials and Oracle Spatial. It includes new versions of Devart.Data.Oracle.Entity.dll and Devart.Data.Oracle.Entity.Migrations.dll assemblies built for .NET Framework 4.5 (Entity Framework v5) and the new unsigned Devart.Data.Oracle.Entity.SharpMap.dll assembly for SharpMap library support.
