Doing experiments testing the usability of WinForms and .NET 8 for conversion of legacy .NET 4.8 projects I run into peculiar blind spots:

On just an empty Form with both a TextBox and a BindingSource (dragged from the Toolbox Panel), it seems there is no way of setting the TextBox ‘Text’ property data binding to a property of the BindingSource instance (like it used to be possible with .NET 4.8).

Of course, programmatically this is still possible using e.g.

this.textbox1.DataBindings.Add("Text", this.bsMain, "name");

(where ‘bsMain’ is the name of Form1’s BindingSource) but that would defeat the whole purpose of instantiating the BindingSource from the Toolbox in the first place.

Is this still supported/am I overlooking something?
