Remarks

Modifying properties other than UrlString or Url is only guaranteed to yield a correct result when a valid URL is already set in the ResourceDescriptor; further restrictions also apply.

An implicit conversion from a System.String containing the URL of the resource exists. It is therefore common to specify ResourceDescriptor-s as strings, relying on the implicit conversion.
