actually, I am a beginner and am learning C#, ASP.NET MVC, and SQL-server from kudvenkat youtube channel, and he taught everything in an awesome way. I am very comfortable with it. and Kudvenkat`s videos are 10 years old and he has used .NET 4.0 to teach C#, asp.net MVC, and WEB-API that`s why I am asking you if I learn C#3.0 and 4.0 and ASP.NET MVC 4 then any issue? I will be able to work on C#, ASP.NET MVC, and WEB-API with .NET Framework 4.0,4.5,4.6,4.7 AND 4.8 and with the organization?
because Fundamental concepts like syntax, the structure of the program, and all other basic concepts do not change from version to version then really I will be able to work with the organization on .NET Framework 4.0,4.5,4.6,4.7 and 4.8? and I will also learn new things about versions while working with the organization and then any issues?
