Я только что создал место для размещения своего веб-приложения.Однако, когда я изменяю строку подключения, чтобы она указывала на SQL-сервер моего провайдера, я получаю сообщение об ошибке.
Строка выглядит следующим образом:
<connectionStrings>
<add name="ApplicationServices" connectionString="Data Source=d5d3955e-1183-4e10-8892-9f9d005af0a8.sqlserver.sequelizer.com;Initial Catalog=dbd5d3955e11834e1088929f9d005af0a8;Persist Security Info=True;User ID=juydqjglrdwrhgsr;Password=***********" providerName="System.Data.SqlClient" />
<add name="TraxzDBEntities" connectionString="metadata=res://*/Models.DBModel.csdl|res://*/Models.DBModel.ssdl|res://*/Models.DBModel.msl;provider=System.Data.SqlClient;provider connection string="Data Source=d5d3955e-1183-4e10-8892-9f9d005af0a8.sqlserver.sequelizer.com;Initial Catalog=dbd5d3955e11834e1088929f9d005af0a8;Persist Security Info=True;User ID=juydqjglrdwrhgsr;Password=***********"" providerName="System.Data.EntityClient" />
</connectionStrings>
Я получаю эту странную ошибку:

Я предполагаю, что строка подключения что-то делает неправильно, кто-нибудь может пролить свет на это?Нужно запустить и запустить этот хостинг, чтобы продолжить мой школьный проект.:)
Обновление: я использую AppHarbor для хостинга, и я выискивал эту проблему и обнаружил следующее:
If you take advantage of the Sequelizer MySQL and MS SQL Server add-ons, SQLSERVER_CONNECTION_STRING and SQLSERVER_URI settings will be injected into your application appSettings. SQLSERVER_CONNECTION_STRING_ALIAS will also be inserted if you add an alias. Further, the connection string will be placed in the connectionStrings element with name set to the alias if one is specified.
The uri is of the following format: sqlserver://username:password@hostname/databasename. If you want, you can create your own connection string (if, for example, you need a custom one for Entity Framework). Here's an example of building a standard connection string:
var uriString = ConfigurationManager.AppSettings["SQLSERVER_URI"];
var uri = new Uri(uriString);
var connectionString = new SqlConnectionStringBuilder
{
DataSource = uri.Host,
InitialCatalog = uri.AbsolutePath.Trim('/'),
UserID = uri.UserInfo.Split(':').First(),
Password = uri.UserInfo.Split(':').Last(),
}.ConnectionString;
Я понятия не имею, что это на самом деле означает, хотя ...Нужно добавить новую строку подключения?и если да, то как мне создать его, чтобы сопоставить с созданными мною сущностями?
