Async procedures. The 10 samples I’ve produced reveals how the above mentioned strategies can be used. Enable’s Look into them just before playing with the sample code:
As it is possible to see, the moment we quit applying our link, we must eliminate it. When we create a link, we are able to utilize it to phone the QueryAsync technique and go the query being an argument. Because the QueryAsync() process returns IEnumerable, we change it to an inventory the moment we wish to return a end result.
