During the installation process, I want to get user input (from the dialog I will create) and replace the values in my appsettings.json file with the user input. I have made a simple edit box and gave it the Property name: AUTHENTEK_URL. when the user enters a value in the box I want that value saved in my JSON file. for the value in the JSON file, I put it as: ["AUTHENTEK_URL_PLACEHOLDER"]. Is it best to approach it through a text file update or a custom action? I would love some help on this, thanks!
