Adding SignalR service as a singleton and then adding redis to it - asp.net-core

Question

Hello i have an app up and running using orleans and signalR and i use a HubConnectionBuilder to initialize my SignalRClient like this
public async Task<HubConnection> InitSignalRCLient()
{
Program.WriteConsole("Starting SignalR Client...");
var connection = new HubConnectionBuilder()
.ConfigureLogging(logging =>
logging
.AddProvider(new LogProvider(Log.logger, new LogProviderConfiguration
{
Category = LogCategory.SignalR,
Level = LogLevel.Warning
}))
)
.WithUrl(Configuration.GetConnectionString("SignalRInterface"))
.Build();
And then i add the service as a singleton in the configure service
services.AddSingleton(SignalRClient)
The problem is now that i want to use redis as a backplane to this and i am having issues adding the redis service to my current way of using SignalR
like this doesn't work
services.AddSingleton(SignalRClient).AddStackExchangeRedis();
according to the documentation https://learn.microsoft.com/en-us/aspnet/core/signalr/redis-backplane?view=aspnetcore-2.2 it wants you to add it like
services.AddSignalR().AddStackExchangeRedis("<your_Redis_connection_string>");
but that doesn't work with how i use SignalR. Is there anyway to get my implementation to work or anyone got any advice on how to tackle this?

Answer 1

Try to add in ConfigureServices this:
services.AddDistributedRedisCache(option =>
{
option.Configuration = Configuration.GetConnectionString(<your_Redis_connection_string>);
});
services.AddSignalR().AddStackExchangeRedis(Configuration.GetConnectionString(<your_Redis_connection_string>));
Also add this in Configure
app.UseSignalR(routes =>
{
routes.MapHub<your_Hub>("/yourHub");
});
And don't forget add abortConnect=False in connectionStrings
