Diagram Control Exception

[Lucas Moffitt]

I understand it's still in beta, but i'm not sure if this has been logged as a bug (might not even be a bug?) or fixed in the next version already.

If i attempt to create a diagram control by duplicating the code from the Sample Browser "NodeContent" I end up with the error listed below. This includes when I drag a new one from the Toolbox after I create DiagramControl.View tags. This includes if i make ANY changes to the sample browser example code.

Any ideas on what's up with this or how to fix it?

---- Error ----

COMException: Error HRESULT E_FAIL has been returned from a call to a COM component.

Hi Lucas,

We have analyzed your regarding “Designer gets crashed while using diagram control”. We are able to reproduce the issue on our side.

There seems to be some issue in WinRT framework, while accessing the Dispatch, which crashes only in designer but not at runtime. However, we consider this as defect and logged a defect report. The fix for this defect will be available on upcoming refresh release.
