How to detect file-based app start directory?

[oconnor0]

Let's say I have the following file-based app pwd.cs that exists at C:\temp\pwd.cs. If I run it from another directory, I seem unable to get that directory name through the usual mechanisms:

// pwd.cs
using System;
using System.IO;
using System.Diagnostics;

Console.WriteLine($"Launched from {Environment.CurrentDirectory}");
Console.WriteLine($"Current directory {Directory.GetCurrentDirectory()}");
Console.WriteLine($"Physical location {AppDomain.CurrentDomain.BaseDirectory}");
Console.WriteLine($"AppContext.BaseDir {AppContext.BaseDirectory}");
Console.WriteLine($"Runtime Call {Path.GetDirectoryName(Process.GetCurrentProcess().MainModule.FileName)}");

PS C:\temp> cd \temp\demo
PS C:\temp\demo> dotnet run ..\pwd.cs
Launched from C:\temp
Current directory C:\temp
Physical location C:\Users\oconnor0\AppData\Local\Temp\dotnet\runfile\pwd-63260d2e1c0271321f59acb93ecb8dc575a5c38590602da4efc12d5507033b5b\bin\debug\
AppContext.BaseDir C:\Users\oconnor0\AppData\Local\Temp\dotnet\runfile\pwd-63260d2e1c0271321f59acb93ecb8dc575a5c38590602da4efc12d5507033b5b\bin\debug\
Runtime Call C:\Users\oconnor0\AppData\Local\Temp\dotnet\runfile\pwd-63260d2e1c0271321f59acb93ecb8dc575a5c38590602da4efc12d5507033b5b\bin\debug
PS C:\temp\demo>

I was hoping that one of these directory/path references would point to the directory the application was launched from (here C:\temp\demo) as that would be useful for scripting. It seems like the app.cs runner logic "reparents" the current directory and execution to the location of the file being run.

Am I just missing something silly?

Sorry, this maybe should have been asked in dotnet/runtime.
