Exercise - Use source code in Visual Studio Code
In this scenario, you have been asked to create an account management app for your organization. You decided to create a canvas app and to make the app source available in text format to comply with the organization's legal requirements. Your company's development policies require that all assets that are created by developers are stored in the source control repository. Source code should be committed to the repository in text format, wherever possible, to simplify the process of collaborating in a project team environment and to make the source available for automatic scanning and differencing.

To complete this exercise, you need to have a Microsoft Dataverse environment with database installed.
