Tuple Awaiter Source Generator

A C# source generator that enables directly awaiting on tuples of Task<T> and ValueTask<T>.

Features

  • Direct tuple awaiting: Await tuples of tasks without explicit Task.WhenAll() calls
  • Mixed task types: Support for both Task<T> and ValueTask<T> in the same tuple
  • Configurable awaiter: Support for both ConfigureAwait(bool) and ConfigureAwait(ConfigureAwaitOptions)
  • Type safety: Preserves strong typing with proper generic constraints
  • Zero runtime overhead: Code generation at compile time with no runtime performance impact
  • Automatic detection: Generates extension methods only for tuple patterns actually used in your code

Usage

Instead of writing:

var task1 = GetStringAsync(); 
var task2 = GetIntAsync(); 
var task3 = GetBoolAsync();
await Task.WhenAll(task1, task2, task3); 
var result1 = task1.Result; 
var result2 = task2.Result; 
var result3 = task3.Result;

You can now write:

var (result1, result2, result3) = await (GetStringAsync(), GetIntAsync(), GetBoolAsync());

The generator supports mixing Task<T> and ValueTask<T> in the same tuple:

var (result1, result2) = await ( /* Task */ Operation1(), /* ValueTask */ Operation2());

It's also possible to configure the awaiter:

var (result1, result2) = await (Operation1(), Operation2()).ConfigureAwait(false);
// ConfigureAwaitOptions is supported too
var (result1, result2) = await (Operation1(), Operation2()).ConfigureAwait(ConfigureAwaitOptions.ContinueOnCapturedContext);

How It Works

The source generator:

  1. Analyzes the code for await expressions of tuples
  2. Detects task types in the tuple elements (Task<T> or ValueTask<T>)
  3. Generates extension methods for the specific tuple patterns you use
  4. Creates custom awaiters that handle the concurrent execution using Task.WhenAll()

Requirements

  • .NET 8.0 or higher
  • C# 9.0 or higher (for tuple syntax support)
