  • Batching Items with EF 6.0

    Headline: It’s not too hard to batch items with or without async capabilities in Entity Framework (EF) 6.0. Here I have a large number (ok… not in the sample test, but in real life) of items and I’d like to pull them in as in batches rather than wait for all of them to be…
