I’m following this tutorial https://learn.microsoft.com/ja-jp/previous-versions/dotnet/spark/tutorials/get-started?tabs=windows to try to test
.Net Spark from Visual Studio.
But at the very begining, got error “System.Net.Sockets.SocketException: The connection was refused by target computer. 127.0.0.1:5567”.
Tried different port number but the simillar error message again and again.
OS: Windows11.
What’s wrong in here?
