What You'll Learn
- Differentiate programs, processes, and threads in C# and explain resource sharing and sync needs
- Distinguish concurrency, parallelism, and sync vs async execution for correct C# design choices
- Identify and mitigate race conditions, critical sections, deadlocks, and starvation in C# code
- Apply C# synchronization primitives (Mutex, Semaphore, Monitor, lock, events, Interlocked) to coordinate threads
- Analyze atomicity, the C# memory model, barriers, and volatile to ensure correct cross-thread visibility
- Implement interview problems (bounded buffer, token bucket, RW lock, barriers, dining philosophers) in C#
- Build and debug async/await flows using Task, TaskCompletionSource, ConfigureAwait, and custom awaitables

About this course
WHY I WROTE THIS COURSE
Concurrency in C# is one of the most complex and advanced topics brought up during senior engineering interviews. Knowledge of concurrency and multithreading can put interviewees at a considerable advantage. This course lays the foundations of advanced concurrency and multithreading and explains concepts such as Monitors and Deferred Callbacks in depth. It also builds simple and complete solutions to popular concurrency problems like the Reader-Writer and Dining Philosopher Problems that could be asked about in interviews. While prior knowledge of concurrency is not required to finish this course, familiarity with the basics of C# would be helpful.
