ASP.NET MVC vs MS PowerShell

The framework has many build-in tools, and many packages have been written targeting the framework.

.Net Core can work on any platform.

It's pretty easy to find a job with it and there's plenty of documentation and tutorials around.

There are a lot of resources available to get help.

Asp.NET Core on Linux is fast accordingly to TechEmpower benchmarks.

You can get ordinary details quickly but with complete freedom to make your craft, knowing everything that is happening underneath the cloths. The highly modular system makes it possible to scale small applications to large ones with ease.

Getting your next contract is easy with this on your CV.

The help system is designed to evolve over time; running update-help downloads the latest content.
When searching for help on items, you can simply type help commandname to get information about a command.
If you're not sure what you're looking for, but have a rough idea, you can search on partial command names, or even specify specific verbs to get a list of commands potentially of interest; e.g. help -verb write.
The information in help gives a good overview of the commands you're looking at, along with code examples, so you can see real-world usage without resorting to the web.

When calling a method with multiple parameters, rather than passing one variable per parameter you're able to "splat" one variable to the method, with the parameters taking their values from its properties.

Commands can be chained via the pipeline, allowing output from one to be cleanly fed as input to the next.

PowerShell is installable through Chocolatey.

The language can wrap and interact with code written in other language's, making it highly extensible.

Though Windows Powershell only works on Windows, the open source implementation Pash (http://pash.sourceforge.net/) allows the same language to be run on other OSes.
