    So I know this is possible in code by getting the serialized property with the name "<VariableName>k__backingfield" and binding it in code, but is it possible to do so with a binding path? You can't type '<' or '>' into the binding path field.

    If that works in code, you should be able to explicitly escape the value straight into the uxml. Can you try with "&lt;VariableName&gt;k__backingfield"?

    If it doesn't please report a bug using Help->Report a bug, we'll address it.

    It does work, but you have to edit the uxml directly, as in UI Builder you can't type anything into the binding path that isn't a letter, number, dash, underscore, or period.

    On the other hand, any thoughts on having official support for auto properties with serialized backing fields in UI Builder? They are supported in the inspector as of 2020. So you could just use "VariableName" instead?

    Clearly an oversight, can you fill a bug regarding the UI Builder support for this?
