Hi, it feels like either some bug or misconfiguration:
When starting a basic project (created with dotnet script init), with debugger in latest VSCode, breakpoint in csx file is not being hit on start.

script is trivial:

#! net6.0
#r "nuget: StackExchange.Redis, 2.5.61"
using StackExchange.Redis;

Console.WriteLine("Hello world!");

Breakpoint is on Console.WriteLine

Debug console output goes to this point :

And then pauses.
To actually hit a breakpoint at Console.WriteLine line - I need to press F5\Continue in debugger, which prints an extra dump in Debugger console, hits breakpoint and completes successfully

Not sure if this is directly related, but when I set justMyCode:false in launch.json, I get a separate additional error message right after the first debug output (when execution halts and debugger waits for F5):

Could not load source 'c:\Users\VssAdministrator\AppData\Local\Temp\tmp31E6\Dotnet.Script\Program.cs': Incorrect format of 'source' message..

dotnet script --info output:

dotnet script --info
Version             : 1.3.1
Install location    : /Users/centur/.dotnet/tools/.store/dotnet-script/1.3.1/dotnet-script/1.3.1/tools/net6.0/any
Target framework    : net6.0
.NET Core version   : 6.0.5
Platform identifier : osx
Runtime identifier  : osx-arm64

This issue happens only when debugging .csx files, regular .NET projects work fine in the same environment\vscode.
Hope this is enough info to triage the issue.

This is likely due to stopAtEntry being set in your launch.json

Here's the launch.json that got created with an init command I ran this morning.

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": ".NET Script Debug",
      "type": "coreclr",
      "request": "launch",
      "program": "${env:HOME}/.dotnet/tools/dotnet-script",
      "args": ["${file}"],
      "windows": {
        "program": "${env:USERPROFILE}/.dotnet/tools/dotnet-script.exe",
      },
      "cwd": "${workspaceFolder}",
      "stopAtEntry": true,
    }
  ]
}

If you comment out the stopAtEntry, then it will behave as you desire I believe.

@dafergu2 Thanks, this is indeed the cause. Haven't paid attention to this prop before, looking into this param - it all started to makes sense now. Not a bug, an unexpected feature of VSCode debugger...
