WPF performance and .NET Framework Client Profile related blogs provided by Jossef Goldberg.
Hopefully folks saw my first “WPF 3.5 SP1 Performance on Tablet & Touch-enabled machines” blog.
In that blog I have mentioned that depending on the WPF application and scenario you may see significant performance issues and general sluggishness on Tablet & Touch-enabled machines and even on none-touch machines when UI Automation client apps are running (such as UI Spy, Narrator, Magnifier, etc).
This was especially noticeable during scrolling if the application comprise of many visual elements.
As I mentioned we have already fixed this issue in .NET 4.
I am now happy to announce that we just posted a Hotfix for .NET 3.5 SP1 that you can download from MSDN Code Galley site here and the Connect site here.
