Unable to build the project after adding this nuget package

Hi!

I am getting the following error saying that the key has already been added. Please find the logs below -

Severity	Code	Description	Project	File	Line	Suppression State

Any idea what might be the issue?

Thanks!

Does that icon file exist multiple times? Holen Sie sich Outlook für Android<https://aka.ms/ghei36>

@romerod - Yep! I deleted those files from the packages folder as well (Using Dotnet Core 3.0) but still the same error has happening. I have zeroed the error to this line -

usedPackages.Add($"{id}.{version}".ToLowerInvariant());

But that file exists across various packages and not just 1 single package.
