In the following article Microsoft mentions a way to configure SignalR to use only WebSocket and turn off Negotiation. What is the way to apply this in ASPNet Boilerplate? https://learn.microsoft.com/en-us/aspnet/core/signalr/scale?view=aspnetcore-7.0 Please advise Thanks

Hi,
Thanks. In that case, you can set
abp.signalr.withUrlOptionsto set options of WithUrl. AspNet Zero uses https://learn.microsoft.com/en-us/javascript/api/@microsoft/signalr/hubconnectionbuilder?view=signalr-js-latest#@microsoft-signalr-hubconnectionbuilder-withurl-2 and you can find its options here https://learn.microsoft.com/en-us/javascript/api/@microsoft/signalr/ihttpconnectionoptions?view=signalr-js-latest -

Hi,
For server side, you can modify the line below in your Startup.cs file;
services.AddSignalR(); -
