LinqToAwait
In a world where many methods return Task<T> or other Awaitable types
(especially in WinRT), LINQ can't be used nearly as easily. Enter LinqToAwait:
using System;
using System.Reactive.Linq;
using LinqToAwait;
var inputs = new[] {
"http://www.google.com",
"http://www.yahoo.com",
"http://www.aol.com",
};
IEnumerable<string> results = await inputs.AsAsync()
.WhereAsync(async x => await IsPageInTop10WebSitesByTrafficAsync(x))
.SelectAsync(async x => await DownloadPageAsync(x))
.Select(x => x.Substring(0, 50))
.GetResults();
>>> ["<html>...."]
Where does this work?
You're going to need Visual Studio 2012 - you can use LinqToAwait with .NET 4.5 applications.
Hey, isn't this kind of like Rx?
It is Rx! However, it is a simplification of the API used for a more specific use-case. Instead of choosing async/await or Rx, LinqToAwait helps you use both at the same time, applying the most straightforward technique for the particular problem.
How do I get started?
It's .NET, how else? Use NuGet!.
Install-Package LinqToAwait
