Asyncify by: Hans van Bakel

Asyncify-CSharp is an analyzer and codefix that allows you to quickly update your code to use the Task Asynchronous Programming model. This model, introduced in C# 5, adds an intuitive way of handling asynchronous calls within C#. The analyzer allows large codebases to be easily modified to use the TAP model by finding violations and applying fixes up the call tree.

AsyncEnumerator by: sergiis dasync

Introduces IAsyncEnumerable, IAsyncEnumerator, ForEachAsync(), and ParallelForEachAsync() GitHub: https://github.com/Dasync/AsyncEnumerable PROBLEM SPACE Helps to (a) create an element provider, where producing an element can take a lot of time due to dependency on other asynchronous events (e.g. wait handles, network streams), and (b) a consumer that processes those element as soon as they are ready without blocking the thread (the processing is scheduled on a worker thread instead). EXAMPLE using Dasync.Collections; static IAsyncEnumerable<int> ProduceAsyncNumbers(int start, int end) { return new AsyncEnumerable<int>(async yield => { // Just to show that ReturnAsync can be used multiple times await yield.ReturnAsync(start); for (int number = start + 1; number <= end; number++) await yield.ReturnAsync(number); // You can break the enumeration loop with the following call: yield.Break(); // This won't be executed due to the loop break above await yield.ReturnAsync(12345); }); } // Just to compare with synchronous version of enumerator static IEnumerable<int> ProduceNumbers(int start, int end) { yield return start; for (int number = start + 1; number <= end; number++) yield return number; yield break; yield return 12345; } static async Task ConsumeNumbersAsync() { var asyncEnumerableCollection = ProduceAsyncNumbers(start: 1, end: 10); await asyncEnumerableCollection.ForEachAsync(async number => { await Console.Out.WriteLineAsync($"{number}"); }); } // Just to compare with synchronous version of enumeration static void ConsumeNumbers() { var enumerableCollection = ProduceNumbers(start: 1, end: 10); foreach (var number in enumerableCollection) { Console.Out.WriteLine($"{number}"); } }
