我最近在一个MVC网站上实现了asp.net identity 2。我按照此练习将此pk更改为INT Here
每件事似乎工作正常，我能够按如下方式为用户分配角色：
var result = await userManager.AddToRoleAsync(User.Identity.GetUserId<int>(), "Edit");
但是，我使用Authorize属性时会在操作方法中指定角色，例如：
[HttpPost]
[ValidateAntiForgeryToken]
[Authorize(Roles = "Edit")]
public async Task<ActionResult> Edit(UdlDownload model)
我收到以下错误：
The user instance login flag is not supported on this version of SQL Server. The connection will be closed.

SQLExpress database file auto-creation error:
The connection string specifies a local Sql Server Express instance using a database location within the application's App_Data directory. The provider attempted to automatically create the application services database because the provider determined that the database does not exist. The following configuration requirements are necessary to successfully check for existence of the application services database and automatically create the application services database:
1.If the application is running on either Windows 7 or Windows Server 2008R2, special configuration steps are necessary to enable automatic creation of the provider database. Additional information is available at: http://go.microsoft.com/fwlink/?LinkId=160102. If the application's App_Data directory does not already exist, the web server account must have read and write access to the application's directory. This is necessary because the web server account will automatically create the App_Data directory if it does not already exist.
2.If the application's App_Data directory already exists, the web server account only requires read and write access to the application's App_Data directory. This is necessary because the web server account will attempt to verify that the Sql Server Express database already exists within the application's App_Data directory. Revoking read access on the App_Data directory from the web server account will prevent the provider from correctly determining if the Sql Server Express database already exists. This will cause an error when the provider attempts to create a duplicate of an already existing database. Write access is required because the web server account's credentials are used when creating the new database.
3.Sql Server Express must be installed on the machine.
4.The process identity for the web server account must have a local user profile. See the readme document for details on how to create a local user profile for both machine and domain accounts.

app.UseCookieAuthentication(new CookieAuthenticationOptions

LoginPath = new PathString("/Account/Login"),
Provider = new CookieAuthenticationProvider
{
// Enables the application to validate the security stamp when the user logs in.

OnValidateIdentity = SecurityStampValidator.OnValidateIdentity<FskUserManager, FskUser, int>(
validateInterval: TimeSpan.FromMinutes(30),
regenerateIdentityCallback: (manager, user) =>
user.GenerateUserIdentityAsync(manager),
getUserIdCallback: (id) => (id.GetUserId<int>()))

// regenerateIdentity: (manager, user) => user.GenerateUserIdentityAsync(manager))
}
});
app.UseExternalSignInCookie(DefaultAuthenticationTypes.ExternalCookie);
}
导致我的问题是什么？我觉得我遗漏了一个重要的步骤，我告诉asp.net框架使用我的RoleStore而不是默认的？
这是我的连接字符串：
<add name="IdentityDbContext" connectionString="Data Source=LOCALHOST\SQLEXPRESS;Initial Catalog=FSK_FskNetworks;persist security info=True;user id=sa;password=p@ssword;MultipleActiveResultSets=True;application name=EntityFramework" providerName="System.Data.SqlClient" />
在我的连接字符串上方添加<clear/>后。

答案 0 :(得分：4)
您的machine.config文件已包含某些值，例如连接字符串，成员资格提供程序和角色管理器设置，而您的web.config文件会从那里继承所有设置。
计算机上的machine.config文件设置为使用名为LocalSqlServer的连接字符串添加成员资格提供程序。因此，当您使用Authorize属性时，它首先尝试使用该提供程序而不是Identity。角色经理也是如此。
您可以通过清除web.config中的现有提供商来禁用此功能：
<configuration>
....
<system.web>
...
<membership>
<providers>
<clear/>
</providers>
</membership>
<roleManager enabled="false" />
</system.web>
</configuration>
此外，您可能需要将其添加到appSettings：
<appSettings>
<add key="enableSimpleMembership" value="false" />
</appSettings>
