MySqlException: Table 'searchhome.aspnetusers' doesn't exist

So I wanted to do the following: I have already created a simple database with a table. On that db table some values have been added. I wanted to display that added value on my simple ASP.NET Core app. However, the dotnet run gave me the error as per screenshot attached (aspnetusers does not exist) The dotnet ef database update leads to the same error (aspnetusers does not exist). I have tried adding that aspnetuser table or tried updating the database( INSERT INTO __EFMigrationsHistory (MigrationId, ProductVersion) VALUES ('00000000000000_CreateIdentitySchema', '7.0.2');) None of these helped me out....

✅ False Positive Virus Detection on my C# network ping code

So i'm trying to make a simple ping utility that just given a bunch of hostnames, does a ping to the host periodically, and graphs the results. I can make the app and it works fine for my needs. But I publish it and send it to my buddy to have a look at and his corporate Windows Defender says its a virus and deletes it.

Why do we enclose the `Main` function inside of a class in C#?

After learning C++, I think it makes sense to include the main function outside of a class. Why do we not do it in C#? Like what disadvantage I would have by not including the main function in a class in C++? Would it be accessible to everyone? Does including the Main method in a class in C# make it "safer" than it being present at a global scope? What is the reason behind this?...

✅ ASP.NET 'web' application

My exercise says the following:

The path of the folder where we store the addresses should be customized: extend your program to read it from the appsettings.

. I think I should just make the path (which is a json file) an environment variable in the appsettings. Does that make sense to do or should I just ask the teacher? If there are any other options that might work with the use of appsettings then please tell me....
