I read the book https://learn.microsoft.com/en-us/dotnet/architecture/dapr-for-net-developers/getting-started and build the sample
"Multi-container Dapr application".
When I run the self-hosted model I receive an error:
Microsoft.AspNetCore.Diagnostics.DeveloperExceptionPageMiddleware[1]
An unhandled exception has occurred while executing the request.
Dapr.Client.InvocationException: An exception occurred while invoking method: 'weatherforecast' on app-id: 'MyBackEnd'
---> System.Net.Http.HttpRequestException: No connection could be made because the target machine actively refused it. (127.0.0.1:3500)
I have restarted my computer but the error appears again. How to fix it? My OS: Windows 11
