You can read a quickstart guide for this sample here.
In order to run the example you need to just start a server. What we suggest is doing the following:
- Make sure
web.config
contains your credentials. You can find your credentials in the settings section of your Auth0 Client. - Hit F5 to start local web development server.
Go to http://localhost:58105/api/ping
and you'll see the app running :).
