How can I get the serial number of USB storage devices in .Net Core 2.1?
I found different solutions, but sadly they don't work due the lack of Windows registry and WMI support in .Net Core.
In Powershell it's really simple, but I wasn't able to find an implementation in Powershell Core.

SerialNumber

0008_0D02_0021_9852.
I prefer a solution with no extra installation requirements on the clients (Win, Linux, Mac).
This Class performs a series of queries on the WMI Win32_DiskDrive class and its associators: Win32_DiskDriveToDiskPartition and CIM_LogicalDiskBasedOnPartition, to retrieve informations on the active USB Drives on a System (local or remote).
It might seem redundant (probably because it is), since you just asked for the USB Drives Serial Number. But, you never know what you will need next, and it could be useful to someone else.
It requires Microsoft .Net System.Management 4.5 for .Net Core 2.1 (NuGet Package)
Can be easily found and installed using the Visual Studio NuGet Package Manager.
About Linux support, read here:
Windows Management Instrumentation Now A Formal Bus With Linux 4.13
Also, keep an eye out for Windows Compatibility Pack for .NET Core.
New cross-platform assemblies are constantly added and updated.
The main class implements all the required functionalities and it has quite a simple structure.
The WMI queries use the Associator syntax, a method to correlate WMI class objects related to each other.
The Class properties meaning is self-explanatory.
Can be instantiated this way:
SystemUSBDrives systemUSBDrives = new SystemUSBDrives("[Computer Name]");
When [Computer Name] is null or empty, it uses the Local Machine name.
To get the List of USB Devices and their properties, call the GetUSBDrivesInfo() method:
var USBDrivesEnum = systemUSBDrives.GetUSBDrivesInfo([UserName], [Password], [Domain]);
[UserName], [Password], [Domain] are used to connect to a NT Domain.
These parameters, if not needed, can be null or an empty string.
Sample class instantiation and function call (Local Machine, no authentication):
SystemUSBDrives systemUSBDrives = new SystemUSBDrives(null);
var USBDrivesEnum = systemUSBDrives.GetUSBDrivesInfo(null, null, null);

x86 platform driver and mac is not included. I think I really need to write platform aware code the get the serial number of a specific drive. –
