FRONTEND : Angular. BACKEND : Dotnet core API.

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at <MY WEB API URL>. (Reason: CORS request did not succeed). Status code: (null). Dotnet code for API services.AddCors(o => o.AddPolicy("MyPolicy", addcors =>

           {
               addcors.AllowAnyOrigin()
                   .AllowAnyMethod()
                   .AllowAnyHeader();
           }));

app.UseCors("MyPolicy");
