AsyncEnumerator

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(

quot;{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(quot;{number}"); } }

Microsoft.CrmSdk.CoreAssemblies.Async

Adds IAsyncOrganizationService and IAsyncDiscoveryService with async versions of interface methods to the CRM Dynamics SDK. When you call "IOrganizationService.Execute(request)" for instance, it blocks the current thread until the reply is received from the Dynamics CRM server. In case when multiple such operations are running in parallel the app will use too many worker threads (because they are blocked) and will start suffer from performance degradation due to thread exhaustion. To avoid this issue, it's better not to block threads and process server responses as soon as they are available. This extension library allows you to do this using Task Parrallel Library (TPL) and asynchronous calls to Dynamics CRM server, e.g. "await IAsyncOrganizationService.ExecuteAsync(request, cancellationToken)". To use you need to create an async version of the client (Microsoft.Xrm.Sdk.Client.Async.AsyncOrganizationServiceProxy, Microsoft.Xrm.Sdk.Client.Async.AsyncDiscoveryServiceProxy, Microsoft.Xrm.Sdk.WebServiceClient.Async.OrganizationWebProxyAsyncClient, Microsoft.Xrm.Sdk.WebServiceClient.Async.DiscoveryWebProxyAsyncClient) which does asynchronous WCF calls to the service.

AsyncWaitHandle

Use C#/VB await keyword with AutoResetEvent, ManualResetEvent, or Semaphore in .NET apps See examples in README on GitHub: https://github.com/tyrotoxin/AsyncWaitHandle

Dasync.EntityFrameworkCore.Extensions.Projections

Decouples the read model from entities themselves. The read model is automatically generated at runtime from given projection/view interfaces. Essentially works like views for tables in RDBMS. See the project page for examples.
