麻烦使PCL Xamarin（MonoDroid / MonoTouch）兼容

Question

我们已经创建了一个相当强大的PCL，我们希望通过Xamarin在一些Droid / Touch应用程序中使用它。

截至今天，我已经安装了最新版本的Xamarin，并且我已经将我们的PCL设置为使用Profile 158 。

然后我进入了我们的项目并更新了目标组件

• .NET Framework 4.5
• Windows Phone 8
• .NET for Windows Store应用程序
• Xamarin.Android
• Xamarin.iOS

在这之后，我得到了许多编译失败

我是否需要将System dll替换为Xamarin附带的System dll，或者我需要做些什么来使这些东西工作？

注意：如果我上面不清楚，在添加Xamarin目标之前PCL没有任何问题。

根据要求，这是构建输出

不确定是否看到一些代码行会有所帮助，但是，这里有

    public static void Create<TModel> ( this IDbProvider dbProvider, TModel model ) where TModel : class, new()
    {

        var tableName = GetTableName( typeof( TModel ) ); // LINE 25

    }

foreach ( 
    var collection in model.GetType()
                           .GetProperties() // LINE 171
                           .Where(
                               property =>
                               property.GetCustomAttributes( typeof( ManyToManyAttribute ), true ).Any() ) )
{
        if ( !IsGenericList( collection.PropertyType ) )  // LINE 176
            throw new ArgumentException( "The property must be an ICollection<>" );
}

    private static bool IsGenericList ( Type type )
    {
        if ( type == null )
            throw new ArgumentNullException( "type" );

        return type.GetInterfaces() // LINE 239
                   .Where( i => i.IsGenericType )
                   .Any( i => i.GetGenericTypeDefinition() == typeof( ICollection<> ) );
    }

Answer 1

除了列出的其他目标外，Profile158还针对Silverlight 5。 在添加Xamarin支持之前，您的目标是什么？

要尝试的一件事是定位Profile78，它应该是您列出的平台集。

如果这不起作用，您可以使用从构建输出中复制的错误更新您的答案吗？ 屏幕截图中的错误很难阅读，并且不清楚它们是否都来自同一个项目。
