Creating QueryTask

[aburakab]

QueryTask will help us to do a single roundtrip for all queries.

var customersQueryTask = context.Customers.AsQueryTask();
var productsQueryTask = context.Products.AsQueryTask();

// One roundtrip to Database
await QueryTask.WhenAll(customersQueryTask, productsQueryTask);
var customer = customersQueryTask.Result;
var products = productsQueryTask.Result;

I'm not sure if we have something similar in the current version?

Looks like the Future Queries Here are doing the same thing

Executing multiple LINQ queries in a single batch/roundtrip is trakced by #10879.

Specifically for the code above, AsQueryTask isn't part of EF Core or standard .NET, where is it coming from? Note that EF Plus is a separate product that isn't maintained by the EF Core team.

It's just an Idea (AsQueryTask is not existed)! and I realized that it's called ".Future" in that Product.

OK, thanks for clarifying. This indeed looks like a duplicate of #10879.
