Possible problem on Net Core 2.1

[sophisma]

Hi, I'm trying to use this NuGet on a NET Core 2.1 web api project and it keeps saying that it can't find the ExchangeRate namespace on the line:

using ExchangeRate;

Also tried on a newly created NET Core 2.2 project and it gives the same error.

Edit
Downgraded to version 1.0.3 and the namespace is found, the thing is that on version 1.0.5 there was an update on the Google url.
The NET Core version doesn't seem to be the issue.
