WPF app with Api key not working

[papillon2k2]

Hi, noob here.

I have created an Location Platform Account (or so I think... by the way, how can I check what type my account is?).

Then I followed this tutorial to create an API key:

https://developers.arcgis.com/documentation/security-and-authentication/api-key-authentication/api-k... 

And followed this tutorial to create WPF app with a simple map:

https://developers.arcgis.com/net/maps-2d/tutorials/display-a-map/ 

But when I run the app, it shows MainWindow, with the text "powered by Esri" in bottom-right corner, but no map is shown.

In output window, it says "The provided APIKey is invalid, expired or does not have access to the resource."

What am I doing wrong?

note - when creating the API key, in the Referrers step, I did put "*", as I am not sure what to write there... (my app is WPF, so no domain involved...?¿)

Leave the referrer blank and it should work. I reproduced putting in a * will break it.

You can also specify an actual referrer url like this:

And then in the app configure it to use that referrer:

Also make sure you enable at least the basemap service (and anything else you plan on using the key for)

That made it! thanks mate. 

By the way, I have come to know about all this ArcGIS SDK and its possibilites after trying your NmeaParser. Learning a lot with it! (even if its too advanced for my current c# level lol)
