Remarks

Below is an example of using the SaveAsync method. Here, session is the Session instance.

C#

Person personToUpdate = await session.FindObjectAsync<Person>(CriteriaOperator.Parse("Name='Michael Suyama'"));
personToUpdate.Birthday = new DateTime(1986, 10, 31);
await session.SaveAsync(personToUpdate);

VB.NET

Dim personToUpdate As Person = Await session.FindObjectAsync(Of Person)(CriteriaOperator.Parse("Name='Michael Suyama'"))
personToUpdate.Birthday = New Date(1986, 10, 31)
Await session.Save(personToUpdate)

The SaveAsync method also saves all the referenced objects that are aggregated (see the AggregatedAttribute topic for information) and any referenced newly created non-aggregated objects that don’t yet exist in the data store.
