Deferred Exceptions

If you get something wrong, you want to be told about it straight away. But in C#, deferred execution can do the exact opposite.

Topics include:
- .NET async and await
- yield return
- exception handling
- local functions
- optimizing APIs
- deferred execution

Wow this topic is really interesting . I never thought about wrapping async fucntion in sync function where we can make condidtions check. Thanks that can be really usefull

Async methods execute immediately in the same thread they were called in until they hit the await keyword. So the exception blows up there but the state machine catches it and returns faulted task with the same exception.

The task execution is never deferred, it is executed immediatly after being called ?! However, you can choice the place in the proogam where to wait it after being called ?! Can you tell me if i a wrong and why ? Thank you
