Toast Notifications Help

[fperugini]

Hi,
I'm trying to use the Microsoft.Toolkit.Uwp.Notifications NuGet package to show notifications from a VSTO add-in. The project is set to target .NET Framework 4.7.2. I cannot get it to build due to this error:

Could not load file or assembly 'file:///C:\Users\myuserid.nuget\packages\microsoft.windows.sdk.contracts\10.0.19041.1\ref\netstandard2.0\Windows.AI.MachineLearning.MachineLearningContract.winmd' or one of its dependencies. Operation is not supported.

If I use this NuGet package in a standalone .NET 4.7.2 Windows Forms application, it compiles and works OK.

Any ideas why I get this error?

@fperugini not too familiar about VSTO add-in's and that environment, so I'm not sure if that's a supported scenario.
