使用 Windows Azure 1.7 库。

Answer 1

教程(和其他在线资源)主要使用 Azure 1.6 SDK。

It works when in the console application there is a reference to WindowsAzure.StorageClient.dll file from Azure SDK 1.6. Under Azure SDK 1.7 environment there is this error message: Activation error occured while trying to get instance of type Autoscaler, key "". In the error details we find: Could not load file or assembly 'Microsoft.WindowsAzure.StorageClient, Version=1.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040).

解决方案:

A binding redirect in your app.config file will solve the issue:

  <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="Microsoft.WindowsAzure.StorageClient"
                          publicKeyToken="31bf3856ad364e35"
                          culture="neutral" />
        <bindingRedirect oldVersion="1.1.0.0"
                         newVersion="1.7.0.0"/>
      </dependentAssembly>
    </assemblyBinding>
  </runtime>
