Why am I receiving an "Exception from HRESULT: 0xC0000005"

Question

I am reading data in from an external source adding Tables to the diagram when i receive an Exception, raised at

   at System.Runtime.InteropServices.Marshal.ThrowExceptionForHRInternal(Int32 errorCode, IntPtr errorInfo)
   at Microsoft.VisualStudio.ErrorHandler.ThrowOnFailure(Int32 hr, Int32[] expectedHRFailure)
   at Microsoft.VisualStudio.ErrorHandler.ThrowOnFailure(Int32 hr)

   at Microsoft.VisualStudio.Modeling.Shell.DocData.QueryEditFile()

I am obviously missing some crucial DSL features like EMD's or the like.

Interestingly i can manually add MEL's and LINKS to the model, but not automatically, could someone please explain how the diagram fixup process is failing in my case, as I cannot find any documentation that helps explain the issue that is arising?

DOH!

The problem was not linking new MELs into the root MEL for the project. Once i did that the code worked.
