var innerQuery = (from fb in db.tblGroupDetails where fb.GroupDetailID select fb).Take(this.mintPageSize); var result = from f in db.tblGroupDetails where innerQuery.Contains(f.GroupDetailID) select f;

I suspect you just need:

var query = db.GroupDetail
              .OrderBy(...) // You really need an ordering
              .Skip(intSkip)
              .Take(mintPageSize);

You should work out what ordering you want, otherwise "the first N" doesn't have any meaning.

That's not a translation of your query so much as your intent - you should check what SQL it generates.
