Powershell v2 after 4.0 upgrade

[Ross Louch]

Is there a way to open the Powershell 2.0 version after doing the BuildMaster 4.0 upgrade which now uses the .net 4.0 runtime. I am trying to execute scripts against SharePoint 2010 which still uses the old runtime version.

I'm afraid I don't fully understand the problem you're having, .NET 4 can host and run .NET 2 assemblies just fine.

This is the error that I am getting when I run the Powershell script.

Microsoft SharePoint is not supported with version 4.0.30319.1008 of the Microsoft .Net Runtime.

Since this seems like an issue with SharePoint, I'm not sure of a way we could fix this.

The workarounds are of course to run the Execute Command Line action against Version 2 of powershell.exe.

Ross - BuildMaster runs powershell hosted under CLR 4. To work around this, try the following:

C:\windows\system32\windowspowershell\v1.0\powershell.exe -Command {
<YourScriptHere>
}

If you have Params:

Param([string]$SolutionFolder)

C:\windows\system32\windowspowershell\v1.0\powershell.exe -Command {
Param([string]$SolutionFolder)
<YourScriptHere>
}

Example for SharePoint:

Param([string]$Identity)

C:\windows\system32\windowspowershell\v1.0\powershell.exe -Command {
Param([string]$Identity)
Install-SPSolution -identity $Identity -AllWebApplications -GACDeployment -Force
}
