System.Management namespace exception

[Fabi]

Hey!

I just tried to get an app running that is using WqlEventQuery & ManagementEventWatcher from the System.Management namespace.

However the native code generation is already giving me warnings:

The app later will throw with:

This is the code I use:

var query = new WqlEventQuery("__InstanceCreationEvent", new TimeSpan(0, 0, 1), "TargetInstance isa \"Win32_Process\"");
var watcher = new ManagementEventWatcher(query);

while (true)
{
    Thread.Sleep(1);

    // Wait for process start event.
    var e = watcher.WaitForNextEvent();
    var name = ((ManagementBaseObject)e["TargetInstance"])["Name"].ToString().ToLowerInvariant();
    var path = ((ManagementBaseObject)e["TargetInstance"])["ExecutablePath"].ToString();
    var processId = Convert.ToInt32(((ManagementBaseObject)e["TargetInstance"])["ProcessID"]);

    /// do stuff
}

Used command line: dotnet publish -r win-x64 /p:Configuration=Release /p:platform="x64"

System.Management depends on COM interop. CoreRT does not support COM interop currently. It is tracked by #4219
