MVC ELMAH and SQL Azure

背景故事：我们主要使用AWS来进行所有操作（托管、数据库、通知等）。现在，我正在考虑将数据库迁移到SQL Azure，因为我们在AWS RDS上的账单越来越高。所以我尝试在SQL Azure中创建一个数据库，并更新连接字符串以指向新的数据库。过去，ELMAH（特定实现：https://github.com/alexanderbeletsky/elmah.mvc）一直无误地运行。

现状：我刚刚在SQL Azure中创建了一个新的数据库，并立刻注意到关键的差异，即不支持： ON [PRIMARY]，NONCLUSTERED KEYS等。

我成功地迁移了我的数据库（目前），但当我应用了更新后的ELMAH脚本到数据库中并尝试进入工具时，出现了错误！

我某种程度上相信这是一个数据库问题，因为如果我删除： <errorLog type="Elmah.SqlErrorLog, Elmah" connectionStringName="DefaultConnection"/> 它基本上将ELMAH默认为本地存储，我就可以访问ELMAH了。

有人在SQL Azure上成功使用ELMAH了吗？你能给我提供生成表和存储过程的SQL脚本吗？

默认连接字符串是什么样子的（模糊用户/密码/数据库名称）？ - Tommy

这是我在SQL Azure上使用的ELMAH DB脚本：

SQL Azure是SQL的特殊版本，有些功能它不支持。

你是否使用了SQL Azure迁移向导来迁移你的数据库？
