Q: 

Select top on each group using LINQ to SQL?

Hi, I currently have the flowowing object

News:

  • NewsID (PK)
  • CategoryID (FK)
  • NewsTitle

Category:

  • CategoryID (PK)
  • CatName

How can I select the last 5 news for each group using LINQ to SQL? I can't use foreach in this case because it cause multiple query. What should I do to optimize with just one or few query possible?

Thank you
