It is the natural go to class for resource synchronization, but there are alternatives (with caveats). In .Net 4.5 the ConcurrentExclusiveSchedulerPair was introduced, offering a powerful approach to concurrency control. Using this …

Building on the TPL, async and await extend the C# language specification to make task based programming relatively straight forward, and is a huge step forward from APM. However, being able to write code that runs …
