Unable to use SignalR HubConnectionBuilder.WithUrl and HttpConnectionOptions in Core 3.0

Using latest Core 3.0

I’m trying:

    hubConnection = new HubConnectionBuilder().WithUrl("http://localhost:5000/hubs/agenthub", options => options.Cookies.Add(myCookie)).Build();

I get:

Error CS0012 The type 'HttpTransportType' is defined in an assembly that is not referenced. You must add a reference to assembly 'Microsoft.AspNetCore.Http.Connections.Common, Version=3.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'. VoyAdminAgent

If I try to install package Microsoft.AspNetCore.Http.Connections.Common, the latest nuget version is 1.1.0 and I then get:

Error CS1705 Assembly 'Microsoft.AspNetCore.SignalR.Client' with identity 'Microsoft.AspNetCore.SignalR.Client, Version=3.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60' uses 'Microsoft.AspNetCore.Http.Connections.Common, Version=3.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60' which has a higher version than referenced assembly 'Microsoft.AspNetCore.Http.Connections.Common' with identity 'Microsoft.AspNetCore.Http.Connections.Common, Version=1.1.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'

Any help ?

I’m guessing you’re referencing nuget package “Microsoft.AspNetCore.SignalR.Client.Core” instead of “Microsoft.AspNetCore.SignalR.Client”

I see. I moved on and chose another way, so I can’t provide a sample app. Thanks anyway.
