Mastering Asynchronous Programming (Avoid Deadlocks)

Understanding async/await is the difference between an app that supports 5,000 users and one that crashes with only 50 users due to thread exhaustion.

Thread Pool Starvation: The Hidden Killer

When you call .Result or .Wait() on an async task, you are holding onto a thread while it waits. Under load, your **Thread Pool** will run out of available threads because everyone is waiting—this is Thread Starvation.

Final Rule: "Async All the Way"

For any architect, the rule is simple: if one method in the chain is async, **EVERY** method from the Controller down to the Database must be async.
