Support for SQL aliases

[EinsteinBoseCondensate]

As presented in this thread, support for SQL aliases were put down since netcore very beginning. In the link also there's a proposal that I've already added in a local branch. ¿Could I pull request?

You are welcome to do a PR, but this alias thing is only for windows and thereby only .Net Framework or ?

So the PR should only be for that target framework.
