¿Qué causaría un error de 'no se puede cargar el archivo o ensamblado' con respecto a 'Microsoft.WindowsAzure.Configuration'?

Question

Tengo una aplicación Azure de varios niveles en la que he estado trabajando. Utiliza roles de web y de trabajador detrás de una interfaz MVC, así como Azure SQL y almacenamiento de tabla. Ha funcionado bien durante un tiempo, tanto en el emulador como en la nube.

Acabo de comenzar la adición de algunas funciones del servicio de autobús a la misma, añadiendo el paquete de servicio de autobús desde NuGet, y ahora parece que a pesar de todo aún se compila, estoy recibiendo el siguiente error de ejecución:

Server Error in '/' Application.

Observé que el paquete ServiceBus NuGet hace referencia a una versión más nueva de Microsoft.WindowsAzure.Configuration dll (1.7.0.2), y se preguntó si esa podría ser la causa. Intenté anular esto y cambiar todas las referencias a 1.7.0.0 o 1.7.0.2 - ninguno de los dos cambios me ayudó. También intenté eliminar todas las referencias de Azure de la solución y volver a agregar referencias instalando paquetes NuGet y haciendo referencia al último SDK. Esto tampoco ha ayudado.

Debo agregar que en todo momento el dll Microsoft.WindowsAzure.Configuration ha estado en la carpeta bin de la aplicación MVC, y que siempre ha tenido CopyLocal establecido en verdadero.

Noto que el paquete Azure Configuration NuGet se actualizó muy recientemente (viernes 27 de julio), y me pregunto si eso podría tener algo que ver con eso.

¿Alguien sabe cuál podría ser el problema?

EDITAR

sólo para confirmar que la eliminación del paquete de Nuget bus de servicio soluciona el problema. Reestablecerlo hace que el problema vuelva a ocurrir. No sé si esto importa, pero el dll Microsoft.WindowsAzure.Configuration agregado como parte del paquete NuGet parece tener un número de versión incoherente. Si bien la ruta sugiere que la versión debe ser 1.7.0.2:

D: \ Work \ CLIENTS \ PageEngine \ Solutions \ PageEngine \ packages \ Microsoft.WindowsAzure.ConfigurationManager. 1.7.0.2 \ lib \ net35 completo \ Microsoft.WindowsAzure.Configuration.dll

... el número de versión en el inspector de propiedades es todavía 1.7.0.0

Answer 1

Este fue un problema con el conjunto Microsoft.WindowsAzure.Configuration, versión 1.7.0.2

temporalmente fijado por hacer retroceder a cualquiera 1.7.0.1 o 1.7.0.0 y luego se fija permanentemente en 1.7.0.3

Answer 2

Had mismo problema. Revertí Microsoft.WindowsAzure.ConfigurationManager a NuGet versión 1.7.0.1. Ahora está funcionando bien.
