WmiConnections are never closed / disposed

[campersau]

WmiConnections are stored in a dictionary for reuse and are never closed / disposed

Hardware.Info/Hardware.Info.Aot/Windows/WmiLightQueryProvider.cs

Line 9 in 2d594ef

private readonly Dictionary<string, WmiConnection> _wmiConnectionDict = new Dictionary<string, WmiConnection>();

I guess there is a performance reason for caching these WmiConnections otherwise one should be used for each query and then be closed / disposed.
Maybe it would be best to implement IDisposable in IHardwareInfo?

Checked it and indeed caching the WmiConnections helps a lot:
