Question

Hi, this exception is being thrown on code that earlier worked fine. It is a message posting call only, sending a phrase to a message

Answer 1

Hello,

Welcome to Microsoft Q&A!

The Send method should specify a generic argument that represents the sender and data type.

Modify your code as below

   MessagingCenter.Send<object,string>(this, MessageNames.ToastMessageService, msg);  

Refer to https://learn.microsoft.com/en-us/xamarin/xamarin-forms/app-fundamentals/messaging-center#publish-a-message .

Thank you.
