Make any package with dots in id (e.g. companyname.libraryname.librarysubname)
Add some configuration options or use "static" keyword to show linkage options
Install the package
Goto project properties, referenced packages, and try to change the settings, press Apply
Result is error message from VS:
An error has occurred while saving the edited properties listed below:
One or more values are invalid. The name "Linkage-companyname.libraryname.librarysubname" contains an invalid character ".".
The name with dots is AFAIK recommended way to name the libraries. The workaround is to use "-" or whatever instead of dots in the name.
