Good Morning,

I have what I think is a simple question.
 
I have a collection of entities that are already created. However, I need to do some sort of a refresh on this collection from the database. I can (and do) use the RefreshEntitiesAsync() function. However, when I refresh the entities, I need to add an 'Include' to include two more navigation entity properties that were not in the original entities. Ordinarily, if I were doing a query, I'd simply use the Include("XXX") path, but I don't see where refresh lets me do that.
 
Can anyone offer a suggestion?

hi.

You can try this (without using RefetchEntitiesAsync).  the variable myCollection is IEnumerable
var query= myCollection.Cast<MyEntityType>().ToQuery().Include("PropertyName1").Include("PropertyName2");

query.ExecuteQueryAsync( args=>
{
if (args.HasError) //show error

})


//or  you can use
myEntityManager.ExecuteQueryAsync(query, args=>
{
if (args.HasError) //show error
}
);


As you will notice, the query contains a  "where" clause which includes all the pks of the entities in your list. As the entities are loaded into the entity manager cache,  myCollection's entities will be updated accordingly, so you don't need to do anything when the executeQueryAsync gets completed.

Regards,

Guillermo
