AB#1249431

Description

System.Management requires wminet_utils.dll in order to perform must of it's functionality, however this component is missing on some SKUs / architectures of Windows which do not include .NETFramework (eg: ARM64, and others)

Note that the original authors of this component recommend MMI as a replacement: #24803 (comment)

The latest version of this package does support ARM64:
https://www.nuget.org/packages/Microsoft.Management.Infrastructure/

@SteveL-MSFT do you know of anyone porting from System.Management to MMI: is it straight forward?

[danmoseley]

some SKUs / architectures of Windows which do not include .NETFramework (eg: ARM64, and others)

For non ARM64 - I assume you mean Windows Nano? I don't think we've gotten feedback on that gap so I guess ARM64 is the interesting case.

@ericstj should we close this, or at least it should move out of 6.0

[ericstj]

Agreed on moving to future.

I'm going to close this as there's no longer a partner ask and it's a legacy tech.
