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 ????
