More Details On WF/WCF in .NET 4.0

  • Artikel

Steve Martin, a director of product management for CSD, has a blog post containing more information on the work that we are doing for the next versions of WF and WCF that we will release as a CTP at PDC.  He also introduces "Dublin," the name for our efforts around creating a manageable and scalable host for WF and WCF applications, something that I know a few customers would be interested in. 

For you WF and WCF fans, there some more information about some of the features that you'll hear more about at PDC.  I think for customers who are using either today, you'll see something on the list below that gets you interested.  And, if you're not using WF or WCF today, I think there are a few things that might make you interested. We think that the features we're introducing (especially in WF, which is close to my heart) will make it easier to use WF, in more places, and by more people.  Let us know what you think.  What's exciting in the list below, what do you want to hear more about, is there something else you'd like to see on the list?
