✅ SignalR in a background service
I created a worker service project , installed Microsoft.Asp.netcore.SignalR.Client package but i cant add it in the program.cs file.
Error: CS1061 ISericeCollection does not contain the definition for addSignalR and no accessible extension method addSignalR accepting a first argument of type IServiceCollection could be found(are you missing a using directive or an assembly reference?)
How can i configure it?
This is the code:
var builder = Host.CreateApplicationBuilder(args);
builder.Service.AddHostService<Worker>();
builder.Service.addSignalR(); <- here i get the error
var host = builder.Build();
host.Run();

addSignalR and not AddSignalR?this is an another issue i skipped at first

how trustable is chatgpt for counting letters ?
Now how bad will it be for code, since asking for code often means one cannot fully understand the code and just copy/paste it
please don't be suprised that it don't build/don't exist/crash/bug/etc .....

the reason why i suggest him to use common package because i have used in one of my project which is running as a signalr server and i thought he was using server too
but thanks again

yes you are right, but does using common instead of client has some vulnerabilities or problem ?
btw you were 100% right, i was looking how to use authentication on hub and the first i've looked at the ai to find the solution. Now i noticed that microsoft has clean explanation about that :/
