IEnumerable < Product > prodQuery =
from p in db.Products
where p.Category.CategoryName == "Beverages"
Sort of this is what I'm missing for long in Java!!!
Before getting to euphoric about the idea behind LINQ, one should consider a solid and very mature system as SAP (to be exact: the SAP base module, BC).
SAP' native language ABAP supports direct query code to be part of an original ABAP code. I think this is possible since about 20 years.
Congrats to Microsoft and others for not recognizing the need for language-integrated database queries earlier. At leats LINQ adds an additional benefit for querying collections in an SQL-like manner.
