# Visual Studio Blend Timeline Troubleshooting ## Example `` > [!error] > [[Visual Studio Blend]] gives various errors like an element in the control not being in the name scope of the storyboard. This leads to issues like not being able to preview the `Storyboard` in addition to not being able to record changes to keyframes. ## Fix(es) I don't know why this happens, but commenting out or removing the `Storyboard` + all of the elements in the control, saving, then putting it back seemed to fix the issue. I also tried the following, but it didn't make a difference: - Other versions of Blend - Restarting the machine - Uninstalling all versions of [[Visual Studio]], restarting, then reinstalling VS 2022 - Moving the `Storyboard` into the resources of the parent `Grid` - Changing out the `local:NanoViewBase` for a regular `UserControl` #c_sharp #visual_studio #visual_studio_blend #animation
