windows runtime - How to await a method in a Linq query -


trying use await keyword in linq query , this:

the 'await' operator may used in query expression within first collection expression of initial 'from' clause or within collection expression of 'join' clause

sample code:

var data = (from id in ids             let d = await loaddataasync(id)             select d);

is not possible await in linq query, or need structured different way?

linq has limited support async/await. linq-to-objects, useful operation know of select async delegate (which results in sequence of tasks).

list<t> data = new list<t>(); foreach (var id in ids)   data.add(await loaddataasync(id));

if can loaddataasync in parallel safely, example rewritten as:

t[] data = await task.whenall(ids.select(id => loaddataasync(id)));
