When using a simple powershell script, I have an issue passing in a path as a variable:  
  
Parameters  
Working Directory: C:\CI\_WS\Ws\1912\Source\MyProject\deployment&nbsp;  
Executable: C:\WINDOWS\System32\WindowsPowerShell\v1.0\powershell.exe  
Arguments: -NonInteractive -Command "try { invoke-expression -Command ‘C:\CI\_WS\Ws\1912\Source\MyProject\deployment\updateversion.ps1 xml= **C:\CI\_WS\Ws\1912\Source\MyProject\src\MyProject.Windows\Package.appxmanifest** version=’; exit $lastexitcode } catch { $Error[0]; exit 1}"  
Exception calling “Load” with “1” argument(s): “The given path’s format is not supported.”&nbsp;  
At C:\CI\_WS\Ws\1912\Source\MyProject\deployment\updateversion.ps1:7 char:1  
+ $doc.Load($xmlPath)  
+ ~~~~~~~~~~~~~~~~~~~  
+ CategoryInfo : NotSpecified: (I think the path should be escaped (but it’s a variable in my configuration). Maybe you can add a $Utils.EscapePath$ method?

Hi Geert,  
  
The powershell arguments are specified as **-param1 value1&nbsp;-param2 value2**  
  
e.g.

`-xml C:\CI_WS\Ws\1912\Source\MyProject\src\MyProject.Windows\Package.appxmanifest -version ""`

  
or using variables  

`-xml “%xmlPath%” -version "%version%"`

  
I’d add some text to the field description to make this clearer

… and update the placeholder text!

Thanks. Because I used the placeholder example, it went wrong. Now it’s all working fine, thanks.
