Control binding to data source is not working.

  .NET Core Version: 5.0

  No

Problem description:
Binding a control is not working. Example, when attempting to bind a checkbox "checked" state to a my.settings property, the data binding dialog has no data sources to bind to and there are no options to create on.

Expected behavior:
Add binding to a control (example, checkbox) for state, text etc...

Minimal repro:
New .NET 5.0 project, added check box to the form. Navigated to properties, data bindings, checked. Dialog box shows no options.
