System Invalid OperationException The GridCell targetType does not match the type of the element GridCell

[?? ?]

28.1.39 Syncfusion-SfGrid-WPF and Syncfusion-SfSpreadsheet. WPF with the same version number cause a System. Invalid OperationException: "The 'GridCell' targetType does not match the type of the element 'GridCell'

When I tried to introduce Syncfusion. SfSpreadsheet. WPF of the same version 28.1.39. Adding data to the table will trigger this exception. After removing the package of this NuGet, it works normally

Hi liuhaor,

We have analyzed your query and were able to replicate the Ambiguous Type Reference Exception issue at our end when using both Syncfusion.SfSpreadsheet.WPF and Syncfusion.SfGrid.WPF NuGet packages.

This exception occurs because both packages internally reference assemblies that contain classes with the same type names (for example, GridCell). When WPF encounters these overlapping types, it cannot determine which one to use, resulting in the ambiguity error.

For detailed guidance on resolving this issue, please refer to our Knowledge Base article:

How to resolve ambiguous type reference exception in WPF DataGrid

Kindly review the article and let us know if you need any further assistance.

Regards,
