Start with the WebSites composite resource and the DSC configuration shown in the issue, then trace how BindingInfo is represented during MOF compilation. Reproduce the failure with the HTTPS binding example; done means the configuration compiles without the STRING[] to INSTANCE[] conversion error and supports the supplied binding properties.
