Allow automatic variable Is* inside PowerShell module manifest file #9386
Description
NugetPackage have sometimes 2 distincts dll for Windows/Unix plateform.
It's not possible to determine which OS is running from a PowerShell module manifest file.
This issue should be resolved in early PS 7.0 cycle because Net.Core 3.0 will add more scenarios with cross plateforms.
Steps to reproduce
Add a condition with variable IsWindows into the property RequiredAssemblies inside a PowerShell module manifest file.
RequiredAssemblies = @(
if ( $IsWindows ) {
'.\bin\LibName\runtimes\win\lib\netstandard2.0\LibName.dll'
}
else {
'.\bin\LibName\runtimes\unix\lib\netstandard2.0\LibName.dll'
}
)Expected behavior
PowerShell module manifest file is loaded.
Actual behavior
PowerShell Error
import-module : The module manifest 'ModuleName.psd1' could not be processed because it is not a valid PowerShell module manifest file. Remove the elements that are not permitted: At ModuleName.psd1:50 char:10
+ if ( $IsWindows ) {
