Showing results for June 2008 - .NET Blog

A common asynchronous pattern in code today is the pattern known as fork/join parallelism. This typically manifests by starting n pieces of work and later joining with that work. The existing set of the .NET synchronization primitives does not offer a simple solution for handling this common scenario. It can be achieved, for example, by using a Ma...

Some customers discovered that sometimes switch to Design view was very slow. We analyzed submitted reports and tracked the issue down to a code that was discovering available AJAX Extenders and which contols they were applicable to. In order to avoid unnecessary delays we moved discovery of AJAX extenders to a background thread. This made swi...

The June 2008 CTP of Parallel Extensions provides the first look at its 3rd major piece, a set of coordination data structures we lovably refer to as CDS. It contains lightweight and scalable thread-safe data structures and synchronization primitives.  There are of course already many synchronization primitives present in the System.Threading ...

A common problem users run into when writing parallel applications is the lack of the thread-safety support in the .NET collection classes. Users typically need to implement their own synchronization mechanism for achieving the goal of safely reading/writing data to the same shared collection. A largely deprecated solution was to use the synchroni...

We have had complaints from some customers saying that their Web Project build performance with VS is very slow and it turns out that for some of the complaints the actual issue was anti-virus programs running on their machines. So, how do anti-virus programs affect VS build? Please take a look at the following snippet from ScottGu's blog to u...

We have been listening to your [strong] feedback and we are now happy to announce that multiple selection and alignment operations in Design view are coming back and will be included in VS 2008 SP1 RTM and Visual Web Developer Express 2008 SP1 RTM.We do understand that designing pages using absolute positioning of elements is a highly controversial...

There is a natural tension between ordering and performance in a parallel partitioning system such as PLINQ, which we addressed as guidance in the Dec07 CTP documentation:  “Although you can opt into ordering, this does come at a cost to performance because it constrains the options which PLINQ can use for executing a query, so it is bet...

When I was at TechEd 2008 Developer last week, I met up with the great Dan Fernandez from Channel 9 to show off Parallel Extensions and to demonstrate some of the sample applications included with our June 2008 CTP.  The cameras were at the ready, so you can see the demonstrations, too: Thanks, Dan!

I added a blog "ADO.net Data Service reflection class creation in VS2008 SP1 Beta, a breaking change with CTP time" inhttp://blogs.msdn.com/xqiu/archive/2008/05/13/ado-net-data-service-reflection-class-creation-in-vs2008-sp1-beta-a-breaking-change-with-ctp-time.aspxHope it helps for data service lovers.Xin, SDET in Web Development Tools

In Beta1, VS Silverlight tools doesn’t allow users to maintain separate build output folder for different build configuration, and this causes once you switch from “Debug” to “Release” build configuration, under ClientBin folder the existing debug assemblies will be overwritten by the release version. Unless you switch back to “Debug” configuration...
