Minimum PowerShell Host Version Error

[stvpwrs]

When trying to run a script with the Microsoft.Xrm.Data.Powershell module I get the following error:

The current PowerShell host is: '.NET Interactive Host' (version 0.0.1). The module 'C:\Users\...\Documents\PowerShell\Modules\Microsoft.Xrm.Data.Powershell\2.8.14\Microsoft.Xrm.Data.Powershell.psd1' requires a minimum PowerShell host version of '1.0' to run.

I'm not sure if this is an issue with how this module is checking the PowerShell version or something unexpected with the new .NET Interactive Host.

Could you provide example code that reproduces this issue?

Thanks.

The following code will produce the error.

$forMicrosoftXrmDataPowershell = @{
    Force           = $true
    Name            = 'Microsoft.Xrm.Data.Powershell'
    RequiredVersion = '2.8.14'
}
Import-Module @forMicrosoftXrmDataPowershell

Import-Module:

   6 |  Import-Module @forMicrosoftXrmDataPowershell
     |  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
     | The current PowerShell host is: '.NET Interactive Host' (version 0.0.1).

@daxian-dbw Can you provide some insights here? Thanks!

The module manifest of Microsoft.Xrm.Data.Powershell defines PowerShellHostVersion = '1.0', and that means it requires the host to be version 1.0. But the .NET Interactive Host is currently v0.0.1. A quick fix would be to simply change it to 1.0.0, at https://github.com/dotnet/interactive/blob/main/src/Microsoft.DotNet.Interactive.PowerShell/Host/PSKernelHost.cs#L25.

Does that change any behaviors of the host?

[daxian-dbw]

I don't think so. That version was chosen probably just to reflect it was new work. However, changing the version itself may not solve all the problems -- this module depends on the host version being 1.0, but there could be other modules depending on a higher version of the host -- those modules were targeting PowerShell console (thus the PowerShell console host) and ideally should remove that key from the module manifest file unless it really depends on the PowerShell console host.
