 #### Solution
 
 * Remember to close client connection if you use SignalR clients in Azure function or use SignalR client as a singleton.
-* Instead of using SignalR clients in Azure function, you can create SignalR clients anywhere else and use [Azure Functions Bindings for Azure SignalR Service](https://github.com/Azure/azure-sdk-for-net/tree/main/sdk/signalr/Microsoft.Azure.WebJobs.Extensions.SignalRService) to [negotiate](https://github.com/Azure/azure-sdk-for-net/blob/main/sdk/signalr/Microsoft.Azure.WebJobs.Extensions.SignalRService/tests/Samples/BasicNegotiate.cs) the client to Azure SignalR. And you can also utilize the binding to [send messages](https://github.com/Azure/azure-sdk-for-net/blob/main/sdk/signalr/Microsoft.Azure.WebJobs.Extensions.SignalRService/tests/Samples/SendMessages.cs). Samples to negotiate client and send messages can be found [here]([https://github.com/Azure/azure-functions-signalrservice-extension/tree/dev/samples](https://github.com/Azure/azure-sdk-for-net/tree/main/sdk/signalr/Microsoft.Azure.WebJobs.Extensions.SignalRService/tests/Samples)).

 * When you use SignalR clients in Azure function, there might be a better architecture to your scenario. Check if you design a proper serverless architecture. You can refer to [Real-time apps with Azure SignalR Service and Azure Functions](signalr-concept-azure-functions.md).
