Bug ID: 49776
           Summary: .NET application settings are never saved
           Product: Wine
           Version: 5.15
          Hardware: x86-64
               URL: https://github.com/farmerbriantee/AgOpenGPS/releases/d
                    ownload/4.3.10/AgOpenGPS_v4.3.10.msi
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: mscoree
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

For example, no matter how many times I uncheck the "show at startup" dialog,
it will always be there the next time I restart.

These are the only suspicious lines I could spot in WINEDEBUG:

trace:mscoree:ConfigFileHandler_startElement Unknown element L"value" in state
6
trace:mscoree:ConfigFileHandler_startElement Unknown element L"setting" in
state 6
warn:mscoree:ConfigStream_QueryInterface Not supported iface
{2933bf81-7b36-11d2-b20e-00c04f983e60}
warn:mscoree:ConfigStream_QueryInterface Not supported iface
{0c733a30-2a1c-11ce-ade5-00aa0044773d}
fixme:mscoree:parse_supported_runtime sku=L".NETFramework,Version=v4.5" not
implemented

If I install dotnet48 or dotnet462 everything works properly.
