I am trying to use this extension on VS code on Mac with apple Silicon (M2)
As .netcode 3.1 is not supported for mac with silicon processor (needs arm based dotnet installer) i am unable to use the extension. https://dotnet.microsoft.com/en-us/download/dotnet/3.1

Extension needs to be ported to .net 8
