System.Management.Automation namespace not found

I have just upgraded to Windows 10 and one of my libraries fails to compile. The library uses System.Management.Automation and System.Management.Automation.RunSpaces so that I can run PowerShell.

This library compiles on Windows 7 & 8, so I know the code is good.

The error:

Error 3 The type or namespace name 'Automation' does not exist in the namespace 'System.Management' (are you missing an assembly reference?)

I get this same error regardless of which system.management.automation.dll I use, that is the one in 'C:\Program Files (x86)\Reference Assemblies\Microsoft\WindowsPowerShell\3.0' or 'C:\Windows\Microsoft.NET\assembly\GAC_MSIL\System.Management.Automation\v4.0_3.0.0.0__31bf3856ad364e35', the latter is the one which we have in our library which compiles on Win 7/8.

How can I get around this? I want to upgrade our development team in the new year, but this problem will stop that from happening.

Many thanks.

This normally happens that when we upgrade the to new version.

Its just simple ts actually missing the system.management.automation.dll file in the /bin/debug directory.

Open the folder and get in to bin/debug and see if the system.management.automation.dll exist. if does add it as reference to the current solution or you need to find one and add it to solution
