Yes, makes sense maybe.
I suppose without getting into the weeds of it, my knee-jerk would be that if business rules are branching scripting logic then maybe it is anywhere from not awful to preferential for them to live as a part of it.
But I picture a scenario like you are a cloud host and depending on client tier you want to spin some resources up on group A vs group B hardware (more muscle). You might call into C# to get that client tier, but based on the result the A/B specifics are part of the script.

I love to see another cohort participating in such crimes against humanity. This reminds me of about 10 years ago when I cut my teeth with PS at a bank I worked at. I had ended up building a whole Console app AutoUtils.exe in VB.NET for handling day to day maintenance on the dev and QA environments as well as some security auditing functions via Batch files. After the bare metal server migrations to VMs in a blade rack a few months later, IT Jesus decided suddenly PS was king and the only accepted tool for scripting. I left there before I got the chance to rewrite the AutoUtils as PS scripts. But the ability to consume .net appcode directly in PS was something I was excited to leverage.
At my last job, our senior started establishing devops practices and the number of servers between our 2 datacenters was significant. He started using PS with C# helpers for handling specific build workflows between environments and datacenters. Last time I talked to him, he uses it at his new job unraveling several years of user induced "point and click" workflows that had no need being manual. Told me he has written several C# helpers.
No shame in using what works for your use case.

In speaking with a security expert. His #1 recommendation was to disable PowerShell!
He said about 80% of the FILELESS (undetectable) infiltrations use PowerShell.
Since I was not a big user of it, I simply disabled it. It would be TOUGH for me to enable it.
Just an interesting point!

I recently implemented a small service to handle uploads from the browser to our "media server" (rather legacy, don't ask) and on our dev server, no problem. On the actual media server box, I kept getting the dreaded no-access-control-allow-origin header.
Fussed with all the IIS settings and web.config settings to no avail.
Tested vanilla POST calls, all passed CORS without issues.
Learned about "simple requests" which multiform is one of and which don't do an OPTIONS preflight request.
Found an obscure post that people were getting this CORS error on ngnix when the file size was too large.
Tried uploading a a 1K file, and it worked!
Discovered that if the file size was somewhere between by 31K and 67K test files, the larger one failed.
Discovered that if I removed the docInfo parameter:
public IActionResult Upload([FromForm] DocumentUpload docInfo)
The endpoint was hit, no CORS error.
Was thinking, geez, what is .NET 6 doing? Do I have to parse the multiform data myself?
Found a post on the topic that mentioned this code:
var form = ControllerContext.HttpContext.Request.Form;
Tried that and to my horror, it threw an UnauthorizedAccessException that c:\windows\temp\[temp file] is not accessible.
Googled, added IIS AppPool\[my application pool] as a user to c:\windows\temp.
AND IT WORKED.
Unbelievable. An unauthorized access exception results in the browser giving me a CORS error!
This took all week to figure out, spending probably 6 hours a day on it. 
And the small <30K file uploads worked without problems because it didn't require creating a temp file for the stream content.

I have no idea what you're talking about  other than the punch line, which seems to be that this house of cards is shite at generating error messages that are useful for debugging.

Hmmm,

Are you sure that allowing your application pool to use global %TEMP% is a good idea? Everybody can read/write to that location. It's probably more secure if your application pool uses the %USERPROFILE% temp path.
I'm not an IIS expert but I think a better fix would be loading the user profile[^] for the application pool identity. You should dig around for a setting to enable that. This setting will populate your environment variables and should change your temp folder to the %USERPROFILE% temp.
Just a security recommendation.

Agreed - the main point being, the absurd journey it took to discover that this was all the result of not being able to access the temp folder that .NET (or something?) was trying to use to buffer the files being uploaded.

I've had something similar before with something going wrong on the API, but the browser showing it as a CORS error. There's a whole flow that happens and I assume that the initial CORS request fails due to whatever is wrong in the background and the browser then just shows that CORS failed.
On a ASP.Net project I had to put a if statement in for handling CORS Options requests from Angular because it was calling the method like it would have with a normal request. Maybe just a weird setup in my case. With .Net Core I don't think the options request activates the breakpoints, although it looks like you can with some middleware: https://www.codeproject.com/Questions/5162494/Currently-I-am-working-on-angular-and-web-API-NET

Fantastic & interesting post & great detective skills.

I'm filing this one away in my brain for later use.
That is a crazy situation but I totally believe it because of horrors I've seen with similar & IIS & CORS etc.
BTW, was this change needed only on your dev box or did you have to make that change on the Server also?
This is just crazy to me. Can you post the link where you found that solution? Very interesting and quite terrible.

I've never had to make this change anywhere, whether my local devbox, our development server setup, our live servers. It occurred on an obscure server used only as a repository of uploaded files, and it had never seen a .NET application before.
I ended up install VS2022 on it to debug the situation, to some extent I'm glad the VS2022 setup didn't magically "fix" the problem.

One other piece of configuration you need to do: Configure Storage Spaces to run automatically and scrub the temp folder structure after 30 days. IIS is atrocious when it comes to cleaning up after itself.

Looking at the source[^], it seems you can control the directory it uses by setting the ASPNETCORE_TEMP environment variable.
(I found that last week trying to get a .NET 6 API endpoint to accept file uploads with no filename on the Content-Disposition header, to make it match the existing .NET Framework Web API endpoint. Which turned out to be a massive PITA.)
It's probably worth reporting the misleading error in the GitHub repo:

I'm on a 5 year plan to move to Canada, which hubby and I will do assuming things continue to go south here in the states. Living in Canada will be like moving from the meth lab to the apartment above the meth lab, but at least we'll be able to breathe. Learning Canadian English should be fun. I imagine there are lots of synonyms for hockey.

I think that claiming that you are a persecuted minority refugee from a third world country would help more. 
Given the way many Canadians view the US, this may actually work.

We don't think Americans are being persecuted; we're afraid of them.

Please note:
- I never said that Americans are persecuted minorities.
- I never even said that codewitch is part of a persecuted minority.
- I said that given the way many Canadians think of the US, making the claim might be of use.
