How to resolve ApplicationException conflict between mscorlib and Nuget package

Question

Problem

I am attempting to display a pdf file to the users of my Xamarin.Forms Android and iOS applications. I am trying to use the Nuget package Syncfusion.Xamarin.SfPdfViewer.

However, installing the package and recompiling results in the following error:

Error CS0433 The type 'ApplicationException' exists in both 'Syncfusion.Compression.Portable, Version=16.1451.0.37, Culture=neutral, PublicKeyToken=null' and 'mscorlib, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e'

Steps Tried

I have read and heeded the note on the Nuget package:

Note: This package needs to be installed in all Xamarin.Forms projects (PCL, Android, iOS and UWP).

I have searched the web for similar cases such as:

• Xamarin - Could not load assembly 'PCLStorage.Abstractions
• Microsoft.AspNet.WebApi.Client reference conflicts

Specs

I am using:

• Visual Studio 2017 version 15.7.2
• Xamarin version 4.10.0448
• Xamarin.Forms v3.0.0.482510
• NETStandard.Library v2.0.3

Thank you for your help.

Found a workaround. Since good practice is to derive meaningful exceptions from Exception, I created one and used it in place of where I was using ApplicationException. This removed the ambiguity and solution then compiled.

public class ClaimWriterException : Exception
{
    public ClaimWriterException()
    {
    }

    public ClaimWriterException(string message)
        : base(message)
    {
    }

    public ClaimWriterException(string message, Exception inner)
        : base(message, inner)
    {
    }
}
