FileNotFoundException: Could not load file or assembly Syncfusion.sfpopuplayout.XForms

Question

I'm not sure how to resolve this. During runtime, I'm getting an initialization error

System.IO.FileNotFoundException: Could not load file or assembly 'Syncfusion.SfPopupLayout.XForms, Version=18.4451.0.33, Culture=neutral, PublicKeyToken=null'. The system cannot find the file specified.

The file (if this is the correct one) exists here:

C:\Users....nuget\packages\syncfusion.xamarin.sfpopuplayout\18.4.0.33\lib\netstandard2.0\Syncfusion.SfPopupLayout.XForms.dll

This is happening in the constructor of my ContentPage.

The Dependencies/Packages folder shows Syncfusion.Xamarin.SfPopupLayout(18.4.0.33). I see the error is reporting 18.4451.0.33. Is that a significant difference ? What do I do ?

Thanks.

Hi @Peri Hartman ,

Thank you for taking time to post this issue in Microsoft Q&A forum.

Please try to clear NuGet Cache from Tools > NuGet Package Manager > Package Manager Settings > Clear All NuGet Cache(s), after that go to your solution folder and delete the bin and obj folders then rebuild your solution to see if this issue disappear.

Best Regards,
Tianyu
