Hello Stoyan.
I am trying to migrate your nopCommerce-Api-SampleApplication to an Asp.Net Core 2.0 program.
At the point in the "Submit" post where it does the return Redirect(authUrl);, it just hangs up without an error message and there is nothing in the Admin\System\Log.
When I return to using your original sample application, it runs fine.
I was wondering if you could suggest how I would debug this situation.
Thanks,
Tony
