我在Azure上使用Azure SQL数据库运行Razor网站，但已开始收到连接错误消息，指出它无法连接到App_Data localdb - 我不会使用它。我也注意到我的项目很好地重新创建了一个localdb而没有我在某个时候询问它。我已经将Asp身份表迁移到我的天蓝色sql数据库中，所以它在一个地方都很开心（这个好主意吗？对我而言）。无论如何。 localdb消息让我感到困惑，据我所知，我的项目中没有对localdb的引用。我的web.config有2个连接字符串：
我已经用Kudu检查了这些，这就是网站上的实际web.config - 所以没有转换或发布连接字符串。如果我调试azure然后看看
ConfigurationManager.ConnectionStrings我看到4个连接字符串，而不是2.最后2个来自我的web.config，第2个是空白的，第1个读取为：
data source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=true}
我不知道如何以及在何处使用它？
然而，观看ConfigurationManager.ConnecitonStrings[DefaultConnection] 是正确的。我的db模型初始化如下：
public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
public ApplicationDbContext()
: base("DefaultConnection", throwIfV1Schema: false)
{
}
public static ApplicationDbContext Create()
{
return new ApplicationDbContext();
}
...
这样平安无事。值得一提的是，我试图启用站点范围内的SSL，这一切都像这样。我已删除该代码，但问题仍然存在：（
以下是关于我所看到的错误的更多信息：

更新
我的错误就是角色管理员 - 如果我禁用它，问题就会消失......还有角色管理，但仍然！这是一个步骤......
答案 0 :(得分：0)
我的问题的答案是我<roleManager>让我相信我指的是ASP.NET身份2. 他们不一样！ <roleManager>启用了旧版本的身份管理，然后<roleManager>元素默认为localdb。所以...这是额外连接字符串的来源。以下是<roleManager>在Azure中有效machine.config中的显示方式（请注意providers -> connectionStringName）：
<roleManager
enabled="false"
cacheRolesInCookie="false"
cookieName=".ASPXROLES"
cookieTimeout="30"
cookiePath="/"
cookieRequireSSL="false"
cookieSlidingExpiration="true"
cookieProtection="All"
defaultProvider="AspNetSqlRoleProvider"
createPersistentCookie="false"
maxCachedResults="25">
<providers>
<clear />
<add
connectionStringName="LocalSqlServer"
applicationName="/"
name="AspNetSqlRoleProvider"
type="System.Web.Security.SqlRoleProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
<add
applicationName="/"
name="AspNetWindowsTokenRoleProvider"
type="System.Web.Security.WindowsTokenRoleProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
</providers>
</roleManager>
一旦我发现这一点，我就更新了我的web.config以指向我的数据库，如下所示：
<roleManager
enabled="true"
cacheRolesInCookie="true"
defaultProvider="OurSqlRoleProvider"
>
<providers>
<add
connectionStringName="DefaultConnection"
applicationName="/"
name="OurSqlRoleProvider"
type="System.Web.Security.SqlRoleProvider" />
</providers>
</roleManager>
...但这只会产生一个新的错误 Could not find stored procedure 'dbo.aspnet_CheckSchemaVersion'这是因为rolemanager是一种旧形式的asp身份而不是ASP.NET身份2。
（一个小问题，但我发现这个错误的方式只是通过源代码控制，重建，并看到哪个更改破坏了它。）
