- In Visual Studio Code, open the televisionShow folder that you extracted from ch9-start.zip.
- In Explorer, select app.json.
- Find the "runtime" property and hover your mouse over it to see information about it, which should look like this:
The "runtime" property specifies the minimum platform version on which your application can be installed. The number in front of the decimal represents the major platform version, and the number afterward represents the minor platform version, or in other words, the cumulative update number. For example, the project you are working in is currently set as "runtime": "2.3", which means that the minimum platform version allowed is Business Central Fall 2018, Cumulative Update 3.
- Change the "runtime" property value to this:
"runtime": "3.0"
The preceding code block means that the application cannot be installed unless the platform is at least the Business Central Spring 2019 version or higher.
