Please try using an absolute url such like http(s)://<hostname>/api/employees instead of relative url api/employees.
Please note that if the api is located at a cross domain the server of the api must have CORS functionality.
Thanks for the help.
One more thing, how do I include the base address of AddHttpClient in program.cs file? I'd included the following but its not working.
builder.Services.AddHttpClient<IEmployeeService, EmployeeService>(client =>
{
client.BaseAddress = new Uri("https://localhost:7009/");
});
If you use client-side rendered (CSR) components in Blazor Web Apps or Blazor WebAssembly apps, the following Microsoft document will probably help:
Upload files to a server with client-side rendering (CSR)
"The client project (.Client) of a Blazor Web App must also register an HttpClient for HTTP POST requests to a backend web API controller. Confirm or add the following to the client project's Program file:"
builder.Services.AddScoped(sp =>
new HttpClient { BaseAddress = new Uri(builder.HostEnvironment.BaseAddress) });
