Upgrading dotnet ''GridCell' TargetType does not match type of element 'GridCell'.'" when upgrading from .NET 4.6 to .NET 4.6.1 or higher

[Zebedee]

Currently using the following namespaces in the XAML:

xmlns:sfgrid="clr-namespace:Syncfusion.UI.Xaml.Grid;assembly=Syncfusion.SfGrid.WPF"

xmlns:Syncfusion="http://schemas.syncfusion.com/wpf"

Currently installed nuget packages:

• Syncfusion.Compression.Base 19.2.0.44
• Syncfusion.Licensing 19.2.0.44
• Syncfusion.Pdf.Wpf 19.2.0.44
• Syncfusion.Xamarin.Core 18.2.0.45
  

Is there something glaringly obvious I am missing? Apologies I am a bit new to refactoring projects.

Any advice would be more than welcome.

Thank you in advance :)

Hi Zeb,

The exception you reported arises due to a conflict with the "GridCell" class that exists in both the Syncfusion.SfGrid.WPF and Syncfusion.Grid.WPF DLLs. This conflict leads to an exception when you add the reference http://schemas.Syncfusion.com/wpf in your project.

To fix this issue, you can explicitly declare the namespace by specifying the assembly in the following way:

xmlns:sfgrid="clr-namespace:Syncfusion.UI.Xaml.Grid;assembly=Syncfusion.SfGrid.WPF"

Thank you so much for this response. It has resolved the issue.

Turns out a lot of the code has been referencing Syncfusion:GridCell rather than sfgrid:GridCell hence the confusion.

Thank you again :)
