WithUrl() not found in Core 3 client

Question

My .NET SignalR client code not working any more in Core 3 (WPF):

string hubAddress = "https://localhost:44329/Hub";
HubConnection hub = new HubConnectionBuilder().WithUrl(hubAddress).Build(); // WithUrl not found

MS document said it is there

Anyone know how to fix this?

Answer 1

Found a solution: make sure project referencing Microsoft.AspNetCore.SignalR.Client, but not Microsoft.AspNetCore.SignalR.Client.Core.

Answer 2

Remove the dependency Microsoft.AspNetCore.SignalR.Client.Core from you app and then add

Using Package Manager Console

Install-Package Microsoft.AspNetCore.SignalR.Client -Version 6.0.0

Using .Net CLI

dotnet add package Microsoft.AspNetCore.SignalR.Client --version 6.0.0

It will fix your issue
