When starting Visual Studio 2017 Enterprise (15.9.3) with .Net Portability Analyzer 2.5.0.20, I get the following error logged on startup:

Not sure it that's the error that prevents the option from appearing in the right click menu on the solution / projet menu.
A way to bypass the issue is to go in the extensions options (Tools / Options / .Net Portability Analyzer), then the option will appear in the right click menu. (similar to the nuget / migrate packages.config issue)

The same kind of exception occurs at the end of the analysis (it doesn t seem to prevent the completion of the analysis):
