我们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。
到今天为止,我已经安装了最新版本的 Xamarin,并将我们的 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程序集
- .NET 框架 4.5
- 视窗电话 8
- 适用于 Windows 应用商店应用的 .NET
- Xamarin.Android
- Xamarin.iOS
这样做之后,我得到了一些编译失败
我是否需要将System
dll 替换为 Xamarin 附带的那个,或者我需要做些什么才能让这些东西正常工作?
注意:如果我在上面不清楚,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

不确定查看某些代码行是否会有所帮助,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<> ) );
}
