I am embedding a 2D Line Chart, XamChart in a user control, which builds fine, but when I embed that control in another - the parent control and all subsequent parent controls fail in Expression Blend with a 'The enumerator is not valid because the collection changed.' error.
I'm using code directly copied from the feature browser, with relative links fixed, and am assigning datapoints in the C# code behind.
If I build the project from Visual Studio, the project will run and the chart works correctly. But I can not edit any of the parent controls in Expression blend.
I found only one post that touched on this issue:

..and no resolution was ever posted.
Has this issue been looked into? Are there any resolutions?
Hello rablinz,
Has this issue been resolved?
I received the same error message with WPF DV 10.2 in Visual Studio 2010 when I was doing trial license expiration testing. I was able to solve the problem by deleting all content in the licenses.licx file. This file should be located in your project folder under the Properties subfolder.
This might be a different issue than you experienced, as I was advised that this is a common error message in .NET. I would suggest backing up the licenses.licx file and then deleting all content.
