良く知られているように、プロジェクトを起動する方法は、エントリポイント（通常はMain.xaml）をダブルクリックする方法と、Project.jsonをダブルクリックする方法が有りますが、使い分けは必要でしょうか？（例：プロジェクト名を変更した場合は、Project.jsonをダブルクリックした方が良いとか）
Nope it really doesn’t matter on which xaml file you double click. It will open the project if opened on any xaml file of the project.
May be due to translation. Please reshare the question in english if possible.
Hey Gorby this forum is not a StackOverflow to attack someone for trying to help you…
Be more polite and chill a little, it’s hard to understand Japanese(I have been trying to learn it for 1 year) so if someone is thankful, and if it’s not 100% what you asked for explain it if you want help. We are living in the AI era and these tools are not always 100% correct in translation
