[Soufiane]

Hi, I have a community license for syncfusion and I'm working in a xamarin app, but when I add a sample from the essential UI kit, the project doesn't build, and the error is as shown in the image below:

that means :

Error The value cannot be null.

Parameter name: key DeliveryDomain C: \ Users \ soufiane \ source \ repos \ DeliveryDomain \ DeliveryDomain \ Views \ CatalogListPage.xaml 1

and This is the output :

Hi Soufiane, 

 

We have analyzed your query and  we can reproduce the same issue with the Syncfusion xamarin project. Also, we confirmed the issue is only with the Xamarin.Forms version 4.5.0.617 and it is not in the latest Xamarin.Forms version. Hence, you can fix the issue by updating the Xamarin.Forms package to the latest version. For your convenience, I've attached a sample with the updated Xamarin.Forms version.
