\nI did a talk yesterday at TechEd Hong Kong<\/a> on ADO.NET vNext. Most of them just wanted to know what ADO.NET vNext was about. Short and sweet. Here goes…\n<\/p>\n

\nThere are two main new features:
\n1. Entity data model (EDM) – a mapping of objects over relational database to bring data access to a higher level of abstraction. No longer do you need to code to the DBMS schema, only to the entity schema. Think of it as a new data source.
\n2. Entity SQL – a new query language, SQL plus extensions to query against the entity data model (EDM). A bit richer than SQL, but SQL-like.\n<\/p>\n

\nAnd some integration pieces:
\n1. An ADO.NET provider over the EDM (the MapProvider). Uses ESQL queries.
\n2. An ObjectServices layer over EDM. Reminiscent of ObjectSpaces (at least to me). Uses Query<T> and an ObjectContext.
\n3. An integration piece that allows LINQ over the EDM. "LINQ to Entities".\n<\/p>\n

\nLINQ for Entities joins:
\n  LINQ to Objects
\n  LINQ to SQL (was: DLINQ)
\n  LINQ to XML (was: XLINQ)
\n  LINQ to DataSets
\n  PLINQ (parallel LINQ)\n<\/p>\n

\nThat's all folks.<\/p>\n","protected":false},"excerpt":{"rendered":"
