Resource does not install VS

[bminisi]

The resource does detect that absence of VS, but does not start the installation process. It only does the consistency check.

LCM: [ Start Resource ] [[VSInstall]installVS] "},
LCM: [ Start Test ] [[VSInstall]installVS] "},
[[VSInstall]installVS] Checking to see if Visual Studio 2017 is installed"},
LCM: [ End Test ] [[VSInstall]installVS] False in 0.1880 seconds."},
LCM: [ End Resource ] [[VSInstall]installVS] "},
[] Consistency check completed."}

The configuration is as follows (the executable path is "C:\Install\VS\vs_enterprise.exe"):

    VSInstall installVS
    {
        ExecutablePath = $VSInstallPath
        InstallAccount = $Cred
        Workloads = 'Microsoft.VisualStudio.Workload.Azure,Microsoft.VisualStudio.Workload.ManagedDesktop,Microsoft.VisualStudio.Workload.NetWeb,Microsoft.VisualStudio.Workload.Office'
        Ensure = 'Present'
    }

When I try to run the config file into Azure Automation DSC, it fails to compile with the following error:
Exception calling "NewScriptBlock" with "1" argument(s): "At line:6 char:5 + Import-DscResource -ModuleName 'VSInstall' + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Could not find the module 'VSInstall'. At line:25 char:9 + VSInstall installVS + ~~~~~~~~~ Undefined DSC resource 'VSInstall'. Use Import-DSCResource to import the resource." (At line:6 char:5 + Import-DscResource -ModuleName 'VSInstall' + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Could not find the module 'VSInstall'. At line:25 char:9 + VSInstall installVS + ~~~~~~~~~ Undefined DSC resource 'VSInstall'. Use Import-DSCResource to import the resource.)

This is the configuration file I am using :
VSInstall installVS
{
ExecutablePath = $VSInstallPath
InstallAccount = $Cred
Workloads = 'Microsoft.VisualStudio.Workload.Azure,Microsoft.VisualStudio.Workload.ManagedDesktop,Microsoft.VisualStudio.Workload.NetWeb,Microsoft.VisualStudio.Workload.Office'
Ensure = 'Present'
}
