Error after upgrading to PowerShell Studio 2018: Could not load file or assembly 'System.Management.Automation'

[dsloderbeck]

Product, version and build: PowerShell Studio 2018 - 64-bit (Version 5.5.149.0)
Operating system: Windows 10 v1709 (64-bit)


I recently upgraded my PowerShell Studio installation (from PowerShell Studio 2015 to PowerShell Studio 2018), and now whenever I create a new project, or open an existing project, I always receive the following error message:

Code: [Select all] [Expand/Collapse] [Download] (Untitled.ps1)

1. Startup.pss: Could not load file or assembly 'System.Management.Automation, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.

As mentioned, this is happening on all projects, and I have not made any modifications to the default "Startup.pss" file.

Also, if I look at the assemblies for the "Startup.pss", I see the following:

I was not receiving this error message when PowerShell Studio 2015 was installed. I've only started receiving this error after I upgraded to PowerShell Studio 2018.

For clarification, here is the "Startup.pss" that is being generated whenever I start a new project and receive this error message:

Simply remove the reference to System.Management.Automation. It is not necessary in later versions of PowerShell Studio.

@davidc,

Thanks for your reply. Since this assembly is automatically added by PowerShell studio whenever I create a new project, I wasn't sure if it was necessary or not, so I didn't want to delete it without checking first. I'll go ahead and delete it now.
