How to run PowerShell Core scripts from .NET Core applications

I wrote an MSDN blog post a few years back (here) that demonstrated how to run PowerShell scripts by hosting the PowerShell runtime inside a C# / .NET application. A few things have changed since that post; including the introduction of .NET Core and PowerShell Core, better async support, and a few new best practices.

In this article we will jump forward to take a look at runspace execution for PowerShell Core and .NET Core applications. Including topics like project setup, runspace usage examples, stream handling, shared app domain use cases, and some helpful troubleshooting tips.

Quick Tip: Windows PowerShell execution policy handling for x64 and x86 processes

Windows PowerShell’s execution policy is well known feature that helps prevent users from accidentally running malicious scripts. I hit an interesting situation recently where Get-ExecutionPolicy showed that I was allowed to run scripts, but in practice I still couldn’t execute scripts from a .NET application’s hosted runspace. What was the problem? The execution policy settings differed across x64 and x86 processes. Since this problem isn’t covered in the official documentation I figured it deserved a quick write-up.
