This feature is not included in our next release. However, you can take a look at the Using custom connectors in MVVM help article ( https://docs.telerik.com/devtools/wpf/controls/raddiagram/howto/custom_connectors) in our documentation which describes how you can populate RadDiagramShape in MVVM scenario using custom code. You can use this approach as an alternative until this functionality is available.

We really need this! Does anyone have alternatives while waiting for this?
