Source code can be found at GitHub TaskSchedular TaskScheduler is a simple and efficient C# .Net library that runs given tasks at the specified date and time. Efficient : There is no polling. Only runs when a task is due. This is achieved though AutoResetEvent. Simple : Merely 8 KB in size. Pretty easy to…
Threading is a complex subject, it is easy to get yourself entangled in threads which don’t behave as you expect them to. There are many constructs and approaches to synchronize threads or achieve parallelism, each with its own quirks and advantages. There are good old threads, there are thread pools, task parallelism, Parallel class, Async…
Following innocuous looking async / await code will cause deadlock. To understand why, lets go into what await does in the above case. 1 Execution starts when the button is clicked and button1_Click event is fired on the UI thread. 2 The method, named LongRunningProcess, is invoked. 3 The lamda expression passed to Task.Run() executes in…
The code we want to run asynchronously could either be CPU-bound or IO-bound. CPU-bound code keeps the CPU busy, requiring intensive processing, calculations etc. On the other hand, IO-bound code frees up the CPU while waiting for an IO operation to complete, for instance, get some data from a web service. Both kinds of asynchronous…
The User Interface (UI) becomes unresponsive when a time taking operation is executed during an event. Consider the following button click event where I have simulated a time taking operation by calling Sleep method. In a real scenario, it could be some processing which produces the result to be shown back on the user interface.…
