Copying code from documentation and license

Question

When copying the code from the documentation (e.g. https://learn.microsoft.com/en-us/aspnet/core/web-api/handle-errors?view=aspnetcore-6.0) do you have to specify in your code where the given code came from and refer to the appropriate license?

Answer 1

It is sample rather than copyrighted, so you do not need an annotation.
