About .Net Backend-developer's Skill and Knowledge

Hello,

What expectation of knowledge and skill as a .Net backend-developer should you enable to handle?

My reflectation is:

*Entity framework .net / EF Core
*Threads
*LINQ
*Object based programming
*Visual Studio XXXX / Visual Studio Code
*ASP.NET MVC / ASP.NET Core / ASP.NET WebAPI
*Azure
*SQL Server
*C#

What more from the list is missing?

What more knowledge is needed that is not only .net development?

Thank you!
