After installing Windows Hyper-V Server 2019 i installed WAC 1910 but after installing Windows Update was updated to 1910.2 when i try enable role base access i see this information:

So we have now version 2007 and still that same problem :\

Did someone form WAC team even check this ?

@Prasidh_Arora i cen give you some insight about this bug after trying to resolve it.

For some reason no matter what i try "Get-DscResource" did not work on Windows Hyper-V server 2016 and 2019. 

Best thing is that i was able to install Role-Base on 18xx version of WAC but after upgrade it was impossible to do.


I tried install modules of DSCResources, PSDSCResources, xDSCResources and still not working :\ still "Get-DscResource" not present. Basically when i try type this i got error that this (in fresh installed OS)

The term 'Get-DscResource' is not recognized as the name of a cmdlet...

i tried to reinstall WMF 5.1 still no result :\

i tried to install modules and sill that same

So its related to DCS not present in other version of Windows Server then Essentials, Standard, Datacenter. I know that some variation of DSC is present in Nano server after reading in blog post and uservoice, more precise package "Microsoft-NanoServer-DSC-Package
