Answer 1

if you opened the project in another version of Visual Studio and you see a message that the framework is different and closed the dialog will appear like this.

• In the project solution, click right and then update.
• Then the same window will appear again of version this framework and you can choose to use the recommended one if you do not want to download the framework version.
• Close and open project again (optional)

You can see all the project folders again.
