Insert, Update, Delete support in Entity SQL (ADO.Net Entity Framework)
According to the ADO.Net Team here and here, there will be no support of DML operations in Entity SQL as part of V1 of ADO.Net Entity Framework (in Visual Studio "Orcas" release").
Bob has raised a good point: While some data stores (for example SQL Compact Edition) do not support stored procedures at all, wouldn't it be better to prioritize DML in Entity SQL over using Stored Procedures? I totally agree with him.
Enjoy!
