AspNetCore.SignalR | Small work in progress for showcasing stuff

I have data and I want to present it to a user without him needing to refresh the page. I am using Asp .net core SignalR like this:

I have a SignalR service and an Uno Platform WASM Client (with Prism). I want to call a hub method, which returns a model. The problem is, i have two identical models (Properties, Methods, etc.) but the client can only receive one of them upon calling the hub methods. With the other model a exception gets thrown on deserialization.

Hub:

I have one Server project and now trying to convert it into Progressive Web Application. When I reference the API, Model, and UI projects to it then the following error comes out:

I've created a Windows Forms .Net Core app with SignalR .Net client. I followd this article https://docs.microsoft.com/en-us/aspnet/core/signalr/dotnet-client?view=aspnetcore-5.0&tabs=visual-studio to add packages and connect to the server. Everything works correctly when the server does not use NewtonsoftJson for serialization\deserialization. Once I enable NewtonsoftJson serialization\deserialization (serialization\deserialization works 100% correctly on the server which I can test using a client written on JavaScript), properties on the server with JsonProperty like the following

I am making a messenger using the client on WPF and the server part on SignalR. The problem is that I don't fully understand why the method in the ChatHub class called: SendMessage s doesn't work, although JoinChatGroup does.

Error: Microsoft.AspNetCore.SignalR.HubException: "Failed to invoke 'SendMessages' due to an error on the server. InvalidDataException: Error binding arguments. Make sure that the types of the provided values match the types of the hub method being invoked."

Server side:

Hub class:

I want to define such a router or Map for my gRPC Server using Enum or similar method

I've a simple Service which named ServerHubService and a Hubs folder which have some classes in it which will be handle every request will be passed by client to my gRPC server

Here is ScreenShot of my Project Project Structure Now as can be seen in the photo The contents of the file are also the image below HubMap.cs

as you can see i want to define a switch case statment to run diffrent classes

Here is my ServiceHubService gRPC class ServerHubService.cs

and finally this my client side call grpc-client.cs

Here is my ServerHub.proto file :

Appreciation for any answers!

I created a signalr backend server based on .net core 3.1 running on docker(debian). It works well when i only create single server deployment on kubernetes. But when i increase replicas to more than 1 ,it works incorrectly. It looks like the redis backplane not working ,and leads to unreachable communication between multiple servers .

Following the official documention,i installed nuget package:

My error:

In my SignalR hub, I use the following method to check whether a user has an active connection:
