简单搜索“android 无法解决之间的冲突”就会发现论坛帖子 here讨论这个问题。以下链接为官方Xamarin bug report揭示the following solution :

将其添加到您的 app.config 中:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <runtime>
        <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
            <dependentAssembly>
                <assemblyIdentity name="System.Runtime" publicKeyToken="B03F5F7F11D50A3A" culture="neutral"/>
                <bindingRedirect oldVersion="0.0.0.0-4.1.0.0" newVersion="4.1.0.0"/>
            </dependentAssembly>
        </assemblyBinding>
    </runtime>
</configuration>
