A strange bug of Blend 4 RC

 We've been breaking our heads about a week because blend 4 RC stop showing visual states of controls in design view.

Here is the simple blend project with single button style inside app.xaml. Could anybody see visual states changes of this button style in blend?



  • I am having a very similar issue. The design view is no longer updating and I can no longer use the property panel to do a render transform.

  • This bug is already in known issue list of Blend 4 RC. I hope RTM will be released soon.

  • Yes, seeing that too...more specifically - Blend 4 RC doesn't show visual changes in design view in response to control template trigger conditions. State changes via VSM are visible, however. At runtime, everything works just fine, regardless of whether visual changes are implemented via control template triggers or VSM.
