	Hi, we are trying to build an vb.net winforms application that imports visio objects from a stencil and uses them in a diagram. So far we made everything work, but when we save the diagram to a string and then try to load it again we get the "the structure of this object has changed" Error and the application opens with a blank diagram(Console output is: Exception thrown: 'System.InvalidOperationException' in MindFusion.Diagramming). it works for some visio objects but with most of them it fails. Edit: Visio Stencil added

	Hi, thank for taking time to help with this issue. Our Project is in vb.net and we save and load to string (no xml). also, we are limited to .net 4.8.

	Thank you for the example code, so far i was unable to reproduce the error with your project. I have however extracted more error code from our codebase: --------------------------- --------------------------- The structure of this object has changed.

We use Tags to include Informations in our nodes, which works fine for shapenodes, might this be a problem in the visionodes?

	What version of the control are you using? We've reviewed vsx.dll git commits and found stencil serialization fixes from last year. If you are on older version, please try current 7.0.2.

	Please try version 7.0.2. The stencil fix we see is from October, so after 7.0.0 release.

	i downloaded the files from the website seen in the screenshot and took the dll's from C:\Program Files (x86)\MindFusion\MindFusion.Diagramming for WinForms\DotNet4 shouldn't those be the files i need?

	nevermind that, i just took the ones that came with your example project it works now thank you for your efforts! one little question, in this newer version of the libraries, my drag and drop behaviour has changed(i implemented my own nodelist since we needed a horizontal layout) is there documentation on this somewhere?

	I guess the installer might have not replaced older assemblies if you didn't uninstall first, or your project had 'use specific version' property enabled for the references. There's some drag-and-drop changes listed for v7.0.1: https://www.mindfusion.eu/onlinehelp/flowchartnet/CC_What_s_New_in_this_Release_...

	i changed the dragindicator but it does not work yet. It does when i set a breakpoint at the DiagramView1.DragEnter eventhandler, so maybe this is timing related?
