When using #Requires -Modules with a hashtable (valid per https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.core/about/about_requires):
Requires -Modules PSWorkflow @{
ModuleName="PSScheduledJob"
ModuleVersion="1.0.0.0"
}
The hashtable is marked as invalid within VS Code:
Cannot process the #requires statement because it is not in the correct format.
The #requires statement must be in one of the following formats:
"#requires -shellid <shellID>"
"#requires -version <major.minor>"
"#requires -psedition <edition>"
"#requires -pssnapin <psSnapInName> [-version <major.minor>]"
"#requires -modules <ModuleSpecification>"
"#requires -runasadministrator"

What version of PSSA is getting loaded into the integrated console. You should be able to check this with:
(Get-Runspace 4).CreatePipeline("gmo psscriptanalyzer").Invoke()
@rkeithhill 1.16.1
OK, that message is coming from PSScriptAnalyzer but in this case it is correct. A #Requires is a special line comment. It can't span multiple lines. Try using this instead:
#Requires -Modules PSWorkflow,@{ModuleName="PSScheduledJob"; ModuleVersion="1.0.0.0"}
@rkeithhill, that was a copy paste directly from about_requires. If it cannot be multi-line I will submit a documentation issue to Microsoft.
I'm ~90% sure that's a doc bug.
@rkeithhill, fair enough. I have honestly never tried. Just working on the EditorSyntax repo. Will submit a doc bug report.
