I’m on the Working With Data section of the course and on the “Code First Migrations” video @ 4:36 he opens the App_Data folder under the solution explorer but for me it’s not clickable. I did run “Update-Database” under the NuGet package manager console but nothing showed up.
Is your connectionString set correctly? Can you use the same connection string to open up in SQL Server Management Studio?
If yes, you could try to Add-Migration DbCreation then Update to see if that resolves.
I really don’t know if the connectionString is setup correctly. How would I see if it is?
You could try this but you may need to change the steps according to your version of Visual Studio.

Once you have the connection string you wanna be able to see if you can connect to it
