Remarks

The AsyncResult property is similar to the Result property, but allows you to fetch data asynchronously.

The code sample below illustrates how to use the asynchronous data fetch.

C#

public void FetchAppointments(FetchDataEventArgs args) {
    args.AsyncResult = dbContext
        .AppointmentEntities
        .Where(args.GetFetchExpression<AppointmentEntity>())
        .ToArrayAsync<object>();
}

VB.NET

Public Sub FetchAppointments(ByVal args As FetchDataEventArgs)
    Dim res = dbContext.AppointmentEntities.Where(args.GetFetchExpression(Of AppointmentEntity)())
    args.AsyncResult = QueryableExtensions.ToArrayAsync(Of Object)(res)
End Sub
