Hello, im fine. You must be very busy. If you look at the last lecture of the course, I uploaded a lecture on upgrading to .NET 5. https://www.inflearn.com/course/%EB%A0%88%EC%9D%B4%EC%A0%80%ED%8E%98%EC%9D%B4%EC%A7%80-%EC%B4%88%EA%B8%89/lecture/62910 If you follow this link, you will see the following in the explanation: "Use HasDatabaseName() method instead of HasName() method." P.S. Section 13. Project Upgrade (.NET CORE 3.1 ➡ .NET 5) lecture has been added. I had to put it at the back because I expected it would be confusing if I put it at the beginning of the course. I hope you understand. Please note that Section 13 covers all deprecated items. I support your efforts. Thank you.
