Can we use @aspnet/signalr node package for client when we are using a dotnet framework 4.8 signalr server?
Trying to build a SignalR web app, using .Net framework server and Angular client. I could not find the option skipNegotiation in the signalr node package. So, can I use the @aspnet/signalr package and implement the option with the same app setup?
