Answer 1

In my case I replace .. in my path with a normal folder path.

TL;DR

I did the "clever" trick of utilising the relative path of my script file as I did not want to hard code my folder address.

"C:\Program Files\IIS Express\iisexpress.exe" /path:"%~dp0..\Lagardsdorren\bin\Debug\netcoreapp2.2\publish" /port:44342

I knew, but it took my some time to realise, that .. is non grata in IIS(express) as it makes it possible to path yourself out of your sites home directory. In my case it didn't but I guess IIS(express) just stops anything with .. in it.

I don't know how to get back to my clever relative path, but that is for another question.
