How can I run NHibenate queries asynchronously?

Question

One way to increase scalability of the server application is to run IO-bound operation (reading files, sockets, web requests, database requests etc) asynchronously. This doe

Answer 1

multiple async calls can be rewritten with Futures

var footask = QueryFooAsync();
var bartask = QueryBarAsync();
var baztask = QueryBazAsync();

var foos = await footask;
var bars = await bartask;
var baz = await baztask;

// do something with foos, bars, baz

can be replaced with

var foos = session.Query().....ToFuture();
var bars = session.Query().....ToFuture();
var baz = session.Query().....ToFutureValue();

await Task.Factory.StartNew(() => var ignored = baz.Value)  // await the results

// do something with foos, bars, baz

this even has the benefit over async code that the roundtrip time is only paid once instead of 3 times.
