Async8

A utility library for simplifying asynchronous programming in .NET.

Features

• Task Extensions: Add timeout handling and cancellation support to async operations.
• Concurrent Execution Helpers: Execute tasks in parallel or process items in batches.
• Async Caching: Cache asynchronous operations for improved performance.
• Retry Policies: Handle transient errors with configurable retries.

Basic Usage

1. Parallel Execution

Run multiple tasks concurrently with a specified degree of parallelism.

using Async8.Helpers; var items = Enumerable.Range(1, 100); await ConcurrentHelpers.ParallelForEachAsync(items, degreeOfParallelism: 4, async item => { await ProcessItemAsync(item); });

2. Async Caching

Cache the results of asynchronous operations to avoid redundant computations.

using Async8.Caching; var cache = new AsyncCache<string, string>(); var value = await cache.GetOrAddAsync("key1", async key => { return await FetchDataAsync(key); });

3. Retry Policy

Handle transient errors by automatically retrying failed operations.

using Async8.Policies; var result = await RetryPolicy.ExecuteWithRetryAsync(async () => { return await ExternalServiceCallAsync(); }, maxRetries: 3, delayBetweenRetries: TimeSpan.FromSeconds(2));

4. Task Timeout

Handle transient errors by automatically retrying failed operations.

using Async8.Extensions; var result = await SomeAsyncMethod().WithTimeout(TimeSpan.FromSeconds(5));
