InvalidOperationException: JSRuntime must be set up correctly and must be an instance of JSRuntimeBase to use DotNetObjectRef. about signalr HOT 2 CLOSED

Hello, thanks for the info.

However, I think you are on the wrong place here. You are using the official Microsoft Client for SignalR. That is only available on Blazor Server Side.

This repo here however, only focus on the client side.

Thank you! I'm closing the issue.

Thanks for your replay .I have just installed "SignalR.Client" namespace but I never used that namespace anywhere in my project.I suppose to uninstall it. Actually I have created Hub in Azure function serverless application.Here In Blazor application ,sending request to get a connection info from Azure serverless Application and pass the "SignalR Service URL" to establish the conncetion .

Here is code where I used for Hub creation :

public static class SignalRInfo
{
[FunctionName("SignalRInfo")]
public static IActionResult Run(
[HttpTrigger(AuthorizationLevel.Anonymous)] HttpRequest req,
[SignalRConnectionInfo(HubName = "ViewLogger")] SignalRConnectionInfo connectionInfo,
ILogger log)
{
return new OkObjectResult(connectionInfo);
}
}

Function for sending Message to SignalR:

public static void Run([QueueTrigger("logqueue")]string myQueueItem,
[Table("LogJournal"), StorageAccount("AzureWebJobsStorage")] ICollector<Models.LogItem> items,
[SignalR(HubName = "ViewLogger")] IAsyncCollector signalRMessage,
ILogger log)

This is output for azure serverless Apllication:

Http Functions:

    SignalRInfo:  http://localhost:7071/api/SignalRInfo

    WriteLog: [GET,POST] http://localhost:7071/api/WriteLog
