Patch to improve perf and reliability of the Workflow Designer

Today the .NET team is releasing a cumulative update patch.  This has all of the QFEs up until a couple of months ago rolled into one patch.  Included as part of that is a patch for WPF that improves the performance of the Windows Workflow Designer as well as a hang that a number of folks have hit.  I had a few customers try it out, and they were happy with the improvements.  I recommend this update to you if you work with the WF Designer (e.g., editing the workflow for Team Build definitions).  There are still perf issues even with this fix, and the WF Designer team has made some very good perf improvements for the next release.

You can find a complete list of the issues fixed at KB 2468871 under More Information.  There are also six features related to ASP.NET and Silverlight listed after the issues.

Here is the download page:


P.S.  This is completely unrelated to the TFS cumulative update that Brian has written about here.  I recommend both.

    The download pages shows this as being published on 6/8/2011 and the KB is from July…? Is there something new today?

  2. buckh says:

    Andy, the KB and the download page show different dates as the KB article was updated after the download page.  The cumulative update is also available through Windows Update today as a recommended update.

    Hi Buck, your posting says the following "WF Designer team has made some very good perf improvements for the next release."  Are you referring to the .NET Framework 4.0 SP1 as the next release?

    Kevin, I'm actually referring to VS 11 where they have made some significant improvements.
