I am trying to use your code

with DotNetCore 2.2 and Angular 8

I enable CORS like below in my startup class

services.AddCors(options => options.AddPolicy("Cors", builder =>
            {
                builder.AllowAnyOrigin()
                       .AllowAnyMethod()
                       .AllowAnyHeader();
            }));

there is some thing strange in the response

when I console.log(r.headers) at line 22

unfortunately there is no x-miniprofiler-ids in the header object

but in fiddler and chrome network tab the x-miniprofiler-ids do exists in the response object

so UI does not show the miniprofiler detail notifier

is there any thing extra which i have to do ???

is there any specila config for dot net core or angular or httpclient ???

is your code compelete and well tested ????
