Common Errors

If you get the following error: Cannot animate ... on an immutable object instance. it could be that you are run into one of the following issues:

• You are animating a dependency property without having a value set
• You are animating a dependency property who's current value is defined in another assembly that is not merged into the resource dictionary.
• You are animating a value that is currently databound
• You have an invalid property path specified.
