More and more, developers are realizing the significant scalability advantages that asynchronous programming can provide, especially as it relates to I/O. Consider an application that needs to copy data from one stream to another stream, such as is being done in the following synchronous implementation: static void CopyStreamToStream(Stream input...

In concurrent programs, race conditions are a fact of life but they aren’t all bad.  Sometimes, race conditions are benign, as is often the case with lazy initialization.  The problem with racing to set a value, however, is that it can result in multiple objects being instantiated when only one is needed.  Take the LazyInitializer ...

In a previous post, it was demonstrated how for loops with very small loop bodies could be parallelized by creating an iterator over ranges, and then using Parallel.ForEach over those ranges.  A similar technique can be used to write parallel loops over iteration spaces of non-integers.  For example, let’s say I wanted to paralleliz...

In this post we explore some of the ways cancellation is used in Parallel Extensions and explain the guidance we developed. The new cancellation system is a cooperativ...

We recently had a question about how to get more information than an exception’s type provides. The developer was trying to copy a file and didn’t know why the copy was failing. File copies can fail for many reasons, almost all of them what Eric Lippert calls “exogenous conditions”. The developer was catching System.IOExcept...

Grant Richins has a post on the CLR Code Generation team blog that covers the work done to improve the x64 JIT to honor the "tail." instruction prefix, thereby making functional languages like F# more viable. You can find the full post here.
