issue running demo

Thank you for taking the time to write this article.

After downloading and attempting to run the projects and add a new task, I'm receiving an issue with the grpc connection.

the error message is: crit: Microsoft.AspNetCore.Components.WebAssembly.Rendering.WebAssemblyRenderer[100] Unhandled exception rendering component: Status(StatusCode="Internal", Detail="Error starting gRPC call.

Thanks for info. I'll look at it in a reasonable time

@ctwoodwa Do you start both projects? Server and Client? Because the client project is not a hosted project.
