Asynchronous Programming in C#

Content

The course covers the following topics with a strong focus on practical application and hands-on exercises:

– Introduction, Processes and Threads:

• Synchronous vs. Asynchronous programming
• Processes and Thread concepts
• Thread pool
• Worker and I/O Threads
• When not to use the thread pool – Tasks:
• Creating tasks
• Returning data from a task
• Using Tasks or Threads?
• Waiting for tasks – Error Handling in Asynchronous Programming:
• Exceptions in threads
• Exceptions in tasks
• Cancelling tasks:
  • Cancellation Token Source and Tokens
  • Continuations – Async – Await:
  • Async methods
  • Async state machine
  • The await keyword
  • Returning data from async methods
  • Async all the way
  • Async lambdas
  • Optimizing async/await
  • .GetAwaiter().GetResult()
  • WaitAsync – Task Schedulers:
• Async Error Handling:
• Synchronization contexts:
  • SynchronizationContext vs. TaskScheduler
• ConfigureAwait:
  • Capturing the context: – Value Tasks:
  • Tasks vs ValueTasks
  • Performance optimizations

The course is up-to-date with .NET 9 and C# 13 and includes plenty of hands-on exercises for immediate application of learned concepts.

The actual course content may differ from the above depending on the trainer, delivery, duration and the composition of participants.
