According to the documentation, the ProjectLocations property enables you to retrieve all the project locations associated with this project.

That is different from adding a new location; so, according to the documentation, what you are trying to do is not supported. At least not via this property.

Actually, after a quick web search, I found no hint that it is possible to add a project location programmatically at all.
