Hi Eray,
We have checked the reported problem and when using Syncfusion.XlsIO.Portable class library in iOS application, the following settings must be done to execute in iOS devices.
Visual Studio:
In Visual Studio, we can only execute in release mode for iOS device. By setting the link behavior to Link SDK assemblies only.
Xamarin Studio (Recommended):
1. Link behavior: Link SDK assemblies only (otherwise classes you need in Syncfusion.XlsIO.Portable.dll are linked away).
2. Enable debugging: Unchecked (this is to create a smaller binary, since adding debug information makes it somewhat bigger).
Applying these settings will execute the application properly in iOS device.
You might face the following issues, if the above-mentioned build options are missed out.
· You might get "Native linking error" while compiling.
· You might face runtime Exception ("System.TypeInitializationException").
Regards,
Ashok
