Same error here, just created a new Xamarin Forms app, added Syncfusion.Xamarin.SfDataGrid (16.4.0.52) to all projects from Nuget,
calling SfDataGrid from XAML or code:
SfDataGrid d = new SfDataGrid();
On Android got this error:
Unhandled Exception:
System.TypeLoadException: Parent class vtable failed to initialize, due to: VTable setup of type Syncfusion.SfDataGrid.XForms.ExtScrollViewer failed assembly:/storage/emulated/0/Android/data/com.companyname.app/files/.__override__/Syncfusion.SfDataGrid.XForms.dll type:ExtScrollViewer member:(null)
Thank you,
Fabrizio
