Fixing this required the removal of the code that attempted to detect virtual interfaces. Not wanting to remove functionality, but not able to keep the code in place, I implemented a work around solution (see 4 below).
Whilst in the area, I also fixed a few minor bugs i encountered (1, 5, 6 below) and stopped SSDP messages from going out on non-LAN interfaces (3)
All these changes are related.
Changes
1 IsInPrivateAddressSpace - improved subnet code checking
2 interfaces with no gateway were being excluded from SSDP blasts
3 filtered SSDP blasts from not LAN addresses as defined on the network page.
4 removed #986 mod - as this was part of the issue of #2986. Interfaces can be excluded from the LAN by putting the LAN address in brackets. eg. [10.1.1.1] will exclude an interface with ip address 10.1.1.1 from SSDP
5 fixed a problem where an invalid LAN address causing the SSDP to crash
6 corrected local link filter (FilterIPAddress) to filter on 169.254. addresses

This call has nothing to do with static web content and should not have ever been called with the web content path: https://docs.microsoft.com/en-us/aspnet/core/fundamentals/?view=aspnetcore-3.1&tabs=windows#content-root
Since this call is removed, the ContentRoot property is also removed from ApplicationHost as it is no longer needed.
Finally, move validation of the static content path to the DashboardService where it is actually used.

* Fix warnings, improve performance
`QueryResult.Items` is now a `IReadOnlyList` so we don't need to
allocate a new `Array` when we have a `List` (and `Items` shouldn't need to
be mutable anyway)
* Update Providers .csproj to latest C#
* Remove extra newline from DtoService.cs
* Remove extra newline from UserLibraryService.cs
* Compare the MD5 checksum when downloading plugins
* Reduced log spam due to http requests
* Removed 'GetTempFileResponse' function from HttpClientManager
* Fixed caching for HttpClientManager
