在WinRT演示之后,我对.net框架在Microsoft开发堆栈中的作用感到困惑.

是否有必要开发WinRT应用程序？

我有一个像这样的查询linq:

var query = from c in Context.Customers select c;
var result = query.ToList();

Linq查询生成此tsql代码:

exec sp_executesql N'SELECT 
[Project1].[Id] AS [Id], 
[Project1].[Name] AS [Name], 
[Project1].[Email] AS [Email]
FROM ( SELECT 
    [Extent1].[Id] AS [Id],
    [Extent1].[Name] AS [Name], 
    [Extent1].[Email] AS [Email]
    FROM [dbo].[Customers] AS [Extent1] ) AS [Project1]

有没有办法不生成子查询？

在iOS的最新版本中,Apple已经为Objective-C实现了自动引用计数,但我不明白它的作用.
