推荐答案

我相信你看到下面的执行code首先迁移已禁用当您尝试发布您的MVC应用程序：

I believe you see the following "Execute Code First Migration" disabled when you try to publish your MVC application:

这可能是因为无论你做你的应用程序code写的迁移，以及未满code无或描述的这里。

This is potentially because either you do not full code written for Code migration in your application as well no or incorrect DB setup in your web.config as described here.

为了让code启用迁移，你必须有一个DB配置（在Windows Azure中的情况下，你需要提供在web.config中的SQL数据库信息）在web.config中和一个完整的类写在如何code迁移将发生取决于你的模型。 这里是如何实现它的一个例子。

In order to have Code Migration enabled, you must have a DB configured (in case of Windows Azure you need to provide SQL Database info in the web.config) in web.config and a complete class is written on how the code migration will happen depend on your model. Here is an example on how to achieve it.
