У меня есть многоуровневое приложение Azure, над которым я работаю. Он использует веб-роли и рабочие роли за внешним интерфейсом MVC, а также Azure SQL и хранилище таблиц. Некоторое время он хорошо работал как в эмуляторе, так и в облаке.
Я только что начал добавлять к нему некоторые функции служебной шины, добавляя пакет служебной шины из NuGet, и теперь я обнаружил, что, хотя все еще компилируется, я получаю следующую ошибку времени выполнения:
Server Error in '/' Application.

Assembly Load Trace: The following information can be helpful to determine why the assembly 'Microsoft.WindowsAzure.Configuration' could not be loaded.
=== Pre-bind state information ===
LOG: User = JCFXLAPTOP\User
LOG: DisplayName = Microsoft.WindowsAzure.Configuration
(Partial)
WRN: Partial binding information was supplied for an assembly:
WRN: Assembly Name: Microsoft.WindowsAzure.Configuration | Domain ID: 2
WRN: A partial bind occurs when only part of the assembly display name is provided.
WRN: This might result in the binder loading an incorrect assembly.
WRN: It is recommended to provide a fully specified textual identity for the assembly,
WRN: that consists of the simple name, version, culture, and public key token.

Я заметил, что пакет ServiceBus NuGet ссылается на более новую версию библиотеки DLL Microsoft.WindowsAzure.Configuration (1.7.0.2), и задался вопросом, может ли это быть причиной. Я пробовал переопределить это и изменить все ссылки либо на 1.7.0.0, либо на 1.7.0.2 - ни одно изменение не помогло. Я также попытался удалить все ссылки Azure из решения и повторно добавить ссылки, установив пакеты NuGet и сославшись на последнюю версию SDK. Это тоже не помогло.
Я должен добавить, что dll Microsoft.WindowsAzure.Configuration всегда находилась в папке bin приложения MVC, и для нее всегда было установлено значение true для параметра CopyLocal.
Я отмечаю, что пакет NuGet конфигурации Azure был обновлен совсем недавно (пятница, 27 июля), и мне интересно, может ли это иметь к этому какое-то отношение.
Кто-нибудь знает, в чем может быть дело?
ИЗМЕНИТЬ
Просто чтобы подтвердить, что удаление пакета nuget служебной шины устраняет проблему. Повторная установка приводит к повторению проблемы. Я не знаю, имеет ли это значение, но dll Microsoft.WindowsAzure.Configuration, добавленная как часть пакета NuGet, похоже, имеет несовместимый номер версии. Хотя путь предполагает, что версия должна быть 1.7.0.2:
D:\Work\CLIENTS\PageEngine\Solutions\PageEngine\packages\Microsoft.WindowsAzure.ConfigurationManager.1.7.0.2\lib\net35-full\Microsoft.WindowsAzure.Configuration.dll
... номер версии в инспекторе свойств по-прежнему 1.7.0.0
