Notifications support for net4.8

[daniell0gda]

Hello!

I am using winforms2 so I am stuck with net4.8 but I thought it's okay because Microsoft.Toolkit.Uwp.Notifications says that it supports net461 but...!

When building I've got this error:

I've only used this code:

new ToastContentBuilder()
      .AddText(e.Data.Title)
      .AddText(e.Data.Body)
      .Schedule(e.Data.Date, toast =>
      {
          toast.Group = "ABC";
      });

Basically it needs Windows.Foundation.FoundationContract but minimal framework for this package is .NET 5.

What to do? how to live?

Hi @daniell0gda, the Notifications component from WCT 7.x was moved to Toolkit Labs for maintenance and usage on UWP only.

For other desktop apps using the Windows App Sdk, we recommend using the Notification APIs provided by the platform. See the quick start guide for more information.
