I noticed this as well while working on something attach to process related. Glad to know it's not something I just broke :)

Lookin' into it, thanks @ili101!

Has this continued to repro?

[ili101]

Yes still broken in preview

[SeeminglyScience]

Yep it's on my list but I haven't actually done anything to fix it yet.

I was initially thinking it wouldn't be a blocker but this might make debugging pester tests in particular a huge PITA. Assuming Pester still creates anonymous scriptblocks for mocks anyway

From Patrick: The remote file manager is for some reason not populating the file in this scenario, but is creating it.

Easy way to repro: type "Wait-Debugger" in console.

Ok I have a partial answer. Debugging this, in the DebugService we have this bit of code that should be getting the lines of the script...and it's not:

                    PSCommand psCommand = new PSCommand().AddScript($"list 1 {int.MaxValue}");

                    IReadOnlyList<PSObject> scriptListingLines =
                        await _executionService.ExecutePSCommandAsync<PSObject>(
                            psCommand, CancellationToken.None).ConfigureAwait(false);

Hence why that temporary file is empty. scriptListingLines is quite empty!

Sorry this took so long @ili101 but it will be fixed in the next pre-release!
