Error Using Syncfusion Plugin with Visual Studio for Mac 2019

[bbqchickenrobot]

Hi I am using the VS for Mac 2019 version (latest as of this post) with the Syncfusion plugin however it produces a non-buildable solution. The issue seems to be w/ the UI Kit for Xamarin and not the plugin. I am using all of the latest Nuget packages for both Xamarin Forms and Syncfusion UI Kit. I have attached a screenshot for your review.

There error seems to mention that it's having trouble finding INotifyPropertyChanged:

../CheckoutPageViewModel.cs(22,22): Error CS1061: 'CheckoutPageViewModel' does not contain a definition for 'NotifyPropertyChanged' and no accessible extension method 'NotifyPropertyChanged' accepting a first argument of type 'CheckoutPageViewModel' could be found (are you missing a using directive or an assembly reference?) (CS1061)

Easy enough to figure out - Change the OnPropertyChanged to NotifyPropertyChagned which what the UI Kit page models are requesting.

Hi @bbqchickenrobot,

Greetings from Syncfusion.

We have analyzed the reported problem and we would like to let you know that the specified file [BaseViewModel.cs] is already in your application with the same name. And the UI Kit is also having the file in same name [BaseViewModel.cs]. Hence, the UI Kit extension will ignore updating that file in your project to avoid conflicts.

To resolve this, please copy the content from UI Kit BaseViewModel.cs and paste it in your application BaseViewModel.cs file along with the existing content.

Please find the github source file in the below
