Course Info

This course includes 1 attempt.

For the last two decades, computers became faster by increasing the number of CPU cores. However, the fact of having more cores itself doesn’t make a computer drastically faster if those cores are not used by software properly. We, as software developers, should know how to write asynchronous and parallel executing code to make our applications faster and more responsive.

This course is all about developing more responsive and fast programs. Multithreading and Parallel Computing are topics for those who already have some experience in programming, otherwise, you may face difficulties with understanding the content.

Anyway, this course covers:

  • Theoretical foundations of asynchronous programming: main concepts, processes, threads and so on
  • Low-level Thread API, APM, and EAP
  • Task Parallel Library (TPL) including starting tasks, canceling tasks, chaining tasks, waiting for tasks, IO-based tasks, exceptions handling and other
  • Async and Await feature of C#
  • Synchronization including atomicity, Interlocked, Monitor (lock), ReaderWriterLockSlim, Semaphore, SynchronizationContext, and Mutex
  • Signaling constructs such as AutoResetEvent and ManualResetEventSlim, CountdownEvent and Barrier
  • Spinning including SpinWait, SpinLock and our own UpdateableSpin
  • ConcurrentCollections including ImmutableStack, ImmutableQueue, ImmutableList, Immutable Sets, ImmutableDictionary, ConcurrentStack, ConcurrentQueue, ConcurrentBag, BlockingCollection
  • Parallel Programming including Parallel class and PLINQ

Enroll and start learning the foundations of multithreading and parallel computing in .NET.

    • I'm thankful enough for that I love what I do.

      I began my career as a postgraduate student participating in Microsoft ImagineCup contest.

      I've been working with .NET platform since 2003. I've been professionally architecting and implementing software for more than 10 years, primarily based on the .NET platform. I'm passionate about building rich and powerful applications using modern technologies. I'm a certified specialist in Windows Applications and Service Communication Applications by Microsoft. I'm one of the coordinators of the MskDotNet User Group in Moscow.

      What I can say is that software is my art.
