SkiaSharp exception when converting Excel to PDF

Hello, 

I have been attempting to convert an Excel workbook to a PDF document using XlsIO. I am using the latest version of .NET MAUI on Android 12. Here is the error:


---> System.InvalidOperationException: The version of the native libSkiaSharp library (88.0) is incompatible with this version of SkiaSharp. Supported versions of the native libSkiaSharp library are in the range [80.2, 81.0).

How can I go about fixing this?

Hi Michael, 

Greetings from Syncfusion. 

We suspect that the issue occurs due to a specific configuration in your MAUI app. So kindly share the issue reproducing sample, which will be helpful for us in investigating the query and finding the exact root cause for the issue. 

Regards, 
Ramya.

A link to the repository for the app is https://github.com/mvan4310/NSSInvoiceApp


The problem is in the DataService class, inside the ConvertInvoiceToPDF function at line 280. The two lines are commented out at the moment until I could find a fix.

Hi Michael,

Thanks for sharing the details.

We have validated the exception issue and found that the exception is thrown due to an incorrect NuGet package. You are using the Xamarin NuGet instead of the .NET NuGet package, So the exception occurs. We request you to use Syncfusion.XlsIORenderer.NET to resolve the issue.

Please refer to the following link to know more about the required NuGet packages.  
  
Kindly try this and let us know whether it helps.

Regards,
Ramya.

I have updated the Nuget references from Xamarin to .Net versions, and am now experiencing a different but related error:


System.TypeInitializationException

Message=The type initializer for 'SkiaSharp.SKObject' threw an exception.


I have pushed the changes for the nugets and uncommented lines for the XlsIORenderer. I apologize if I am overlooking something.


Edit to Add: I am able to create and modify Excel documents. It seems to be the conversion to PDF that is the only issue.


Final edit: This was solved. It took me removing the packages again, adding them back in, and cleaning the project before rebuilding. I appreciate all the help
