The name ‘GooglePlay Tangle’ does not exist in the current context [FIXED]

When opening the Unity project for my Binary Blitz game for the first time in over a year and on a new computer. I was greeted by the following errors

error CS0103: The name ‘GooglePlay Tangle’ does not exist in the current context

error CS0103: The name ‘Apple Tangle’ does not exist in the current context

The errors are related to the In-App purchasing system used by the game to allow people to pay to remove the ads.

Solution

The solution took me a little while to work out, so hopefully the following will be of use.

  • Open a web browser and visit http://play.google.com
  • Select the affected project
  • On the bottom left click Monetization setup
  • Copy Base64 license key
  • With your affected Unity project open
  • In the menu bar click Services => In-App Purchasing => Receipt Validation Obfuscator
  • Paste in the previously copied monetization license key
  • Click the Obfuscate Google Play License Key button. This will create/recreate the tangle classes in your Unity project
