Whenever I open my .EDMX file for editing, the association lines connecting the various entities are different (and varying wildly) from how I left them when I last closed it.
Here's VS2013's latest drunken spree:
I've tried editing the Diagram XML, but still I've found no success against this.
For example, here's the XML for the longest misbehavior above:
<AssociationConnector Association="Model.FK_InvoiceItems_Invoices" ManuallyRouted="true" >
<ConnectorPoint PointX="2" PointY="11.875" />
<ConnectorPoint PointX="6.5" PointY="11.875" />
</AssociationConnector>
It's pretty straightforward: we should be seeing just one straight horizontal line between Invoices and InvoiceItems. I have no idea how we ended up with this mess. I can drag it back into place, save it and close it, but as soon as I open the file up again it comes back.
Is anyone else having the same problem?
