Microsoft.Bcl.AsyncInterfaces 10.0.0-rc.2.25502.107
About
As of C# 8, the C# language has support for producing and consuming asynchronous iterators. The library types in support of those features are available in .NET Core 3.0 and newer as well as in .NET Standard 2.1. This library provides the necessary definitions of those types to support these language features on .NET Framework and on .NET Standard 2.0. This library is not necessary nor recommended when targeting versions of .NET that include the relevant support.
Key Features
- Enables the use of C# async iterators on older .NET platforms
 
How to Use
using System;
using System.Collections.Generic;
using System.Threading.Tasks;
internal static class Program
{
    private static async Task Main()
    {
        Console.WriteLine("Starting...");
        await foreach (var value in GetValuesAsync())
        {
            Console.WriteLine(value);
        }
        Console.WriteLine("Finished!");
        static async IAsyncEnumerable<int> GetValuesAsync()
        {
            for (int i = 0; i < 10; i++)
            {
                await Task.Delay(TimeSpan.FromSeconds(1));
                yield return i;
            }
        }
    }
}
Main Types
The main types provided by this library are:
IAsyncEnumerable<T>IAsyncEnumerator<T>IAsyncDisposable<T>

                                                     Provides high-performance and low-allocating types that serialize objects to JavaScript Object Notation (JSON) text and deserialize JSON text to objects, with UTF-8 support built-in. Also provides types to read and write JSON text encoded as UTF-8, and to create an in-memory document object model (DOM), that is read-only, for random access of the JSON elements within a structured view of the data.
