条目（数据库）已添加

Question

我有两个应用程序共享同一个数据库，即 API 和 MVC5 应用程序。两者都在本地主机上运行良好，但在部署到我的 Azure 帐户时出现此错误

 Configuration Error

Description: An error occurred during the processing of a configuration
             file required to service this request. Please review the
             specific error details below and modify your configuration file appropriately.

Parser Error Message: The entry 'XlabDatabase' has already been added.

Source Error:

 An application error occurred on the server. The current custom error settings
 for this application prevent the details of the application error from being viewed remotely (for security reasons)

我已采取措施甚至重命名数据库，但在部署时我使用相同的远程字符串

这是我的 MVC 应用程序连接字符串

<connectionStrings>
   <add name="XlabDatabase_acc" providerName="System.Data.SQLClient" connectionString="Data Source=.\SQLEXPRESS;Integrated Security=SSPI;MultipleActiveResultSets=true;App=EntityFramework" />
</connectionStrings>

这是我的 MVC 上下文

    public virtual DbSet<Account> Accounts { get; set; }
    public virtual DbSet<AnnualReport> AnnualReports { get; set; }
    public virtual DbSet<MonthlyReport> MonthlyReports { get; set; }
    public virtual DbSet<WeekReport> WeekReports { get; set; }

    protected override void OnModelCreating(DbModelBuilder builder)
    {
        base.OnModelCreating(builder);
        builder.Entity<AnnualReport>().HasKey<int>(x => x.AnnualReportID);
        builder.Entity<MonthlyReport>().HasKey<int>(x => x.MonthlyReportID);
        builder.Entity<WeekReport>().HasKey<int>(x => x.ReportID);

    }

这是我的 API 连接字符串

  <connectionStrings>
     <add name="XlabDatabase" providerName="System.Data.SQLClient" connectionString="Data Source=.\SQLEXPRESS;Integrated Security=SSPI;MultipleActiveResultSets=true;" />
  </connectionStrings>

这是我的 API 上下文

 public virtual DbSet<Customers> Customers { get; set; }
    public virtual DbSet<Salesman> Salesman { get; set; }
    public virtual DbSet<Route> Route { get; set; }
    public virtual DbSet<Purchase> Purchase { get; set; }
    public virtual DbSet<Products> Products { get; set; }
    public virtual DbSet<Assets> Assets { get; set; }
    public virtual DbSet<WeekReports> WKReports { get; set; }
    public virtual DbSet<MonthlyReports> MONReports { get; set; }
    public virtual DbSet<AnnualReports> ANNReports { get; set; }
    public virtual DbSet<Accounts> Accounts { get; set; }
    public virtual DbSet<LoadingOrder> LoadingOrder { get; set; }


    protected override void OnModelCreating(DbModelBuilder builder)
    {

        base.OnModelCreating(builder);

        builder.Conventions.Remove<PluralizingTableNameConvention>();
        builder.Entity<LoadingOrder>().HasRequired(c => c.Salesman).WithMany().WillCascadeOnDelete(false);
        builder.Entity<IdentityUserClaim>().ToTable("UserClaim").HasKey<Int32>(r => r.Id);
        builder.Entity<IdentityUserLogin>().ToTable("UserLogin").HasKey<string>(l => l.UserId);
        builder.Entity<IdentityRole>().ToTable("Role").HasKey<string>(r => r.Id);
        builder.Entity<User>().ToTable("User").HasKey(r => new{ r.IDNumber, r.UserName});
        builder.Entity<IdentityUser>().ToTable("User").HasKey<string>(r => r.UserName);
        builder.Entity<IdentityUserRole>().ToTable("UserRole").HasKey(r => new { r.RoleId, r.UserId });

    }

我已将这两个应用程序部署到两个不同的虚拟应用程序和目录中。

更新

这就是我部署它们共享相同连接字符串的两个应用程序的方式

我还在连接字符串中添加了Initial Catalog XLAB

Answer 1

在连接字符串上，在<providers> 之后和第一个<add....> 节点之前，添加一个<clear /> 节点。
