Dotnet instructors are strangely insincere, but this lecture is the only one that explains things with sincerity. (Including YouTube, personal sites, and overseas instructors) For example, I have never seen an instructor who explains even a single line of IActionResult. I also heard about Startup files for the first time in this lecture. Dotnet instructors, wake up. Shouldn't you explain at least this much? Isn't it too much to explain by creating a webappmvc project? If that's the case, why do you need a lecture? Just report the Doc. Just follow the Spring instructors. There are also some complaints about this lecture. Dotnet itself is expanded based on various platforms, but the editor is not Visual Studio. (This instructor is not the only one, all Korean instructors are like this.) I wish the lecture was based on vscode + commands under the premise that Visual Studio's convenient functions are missing. (Just like when you do front-end, you don't tell it with npm, you don't tell it with a plugin click.) A similar example is that in the .NET Core lecture, the update-migration command is only for Windows users, so you should tell it based on the dotnet ef command, but since you think that all users will use Windows, you are telling it not about dotnet core, but about .netframework. (You say it's open source, but you tell it about Windows commands? ...)
