Hi, we need to run abp server blazor app in azure accross multi node app service plan so we tried to use Azure SignalR service as Blazor app backplane. We don't have any requirements for SignalR hub hosting in our app from functional point of view (like chat app or similar).

We are getting an exception below when we run the app while Blazor stock app worked just fine with the same configuration. Also, I noticed that based on attached image that the app originally opens the connection to Azure SignalR service but then still tried to connect to local SignalR hub and then fails.

If you're creating a bug/problem report, please include followings:

• ABP Framework version: v4.4.2
• UI type: Blazor
• DB provider: EF Core
• Tiered (MVC) or Identity Server Separated (Angular): no

• Steps to reproduce the issue:"

1. Add Azure SignalR configuration following https://docs.microsoft.com/en-us/aspnet/core/blazor/host-and-deploy/server?view=aspnetcore-5.0
2. if you run localy set the folllowing enviromental variable so SignalR configuration will be enabled. ASPNETCORE_HOSTINGSTARTUPASSEMBLIES = Microsoft.Azure.SignalR
3. Open the app and navigate to another page/view

Could you please clarify if there is a suggested implementation path for Azure B2C integration?

Thanks, Yaroslav
