NOT PRODUCTION READY CODE, JUST AN EXAMPLE

Put your clientId and clientSecret or your Farmmaps-account data (username and password) in a newly created appsettings.secrets.json file inside the root of the Secrets project.
Clone the git repository to a local drive. DON'T clone to a network drive like "My Documents". Latter may cause authentication problems.

appsettings.secrets.json

{
  //API credential sign-in
  "ClientId": "<clientId>",
  "ClientSecret": "<clientSecret>"
}

Or when using a Farmmaps account to sing-in

appsettings.secrets.json

{
 //Sign-in using farmmaps account
 "Username": "",
 "Password": ""
}

• Isn't 100% complete.
• Needs proper testing of all public api methods.
• Needs documentation of all public api methods.
