Issue Description

I am experiencing a problem with commands being inserted into the command history by a debugging session. The additional commands seem to be related to the debugging session. I have reproduced this issue with a simple .ps1 file containing a single variable assignment, with a breakpoint set on the line.

Repro.ps1: $x=1

The entires I’m referring to are Ids 5-9 in the below transcript. The “Get-Variable” entries in the command history appear to be triggered by hovering the mouse over a variable in the editor window to view its value. I’m not sure what triggers the ones.

PS C:\Projects\SQLServerDBA\PowerShellModulesV2> c:\Temp\repro.ps1


PS C:\Temp> get-history

  Id CommandLine
  -- -----------
   1 get-module
   2 gci c:\temp\
   3 c:\Temp\repro.ps1


PS C:\Temp> c:\Temp\repro.ps1



Hit Line breakpoint on 'C:\Temp\repro.ps1:1'
