Question

尝试在Mac上的MVC 6应用程序中从Azure TableStorage读取数据。它可以在PC上运行，但在Mac上用它时会出现这个错误：

TypeLoadException: Could not load type 'Microsoft.WindowsAzure.Storage.Core.Executor.RESTCommand`1[Microsoft.WindowsAzure.Storage.Table.TableResult]' from assembly 'Microsoft.WindowsAzure.Storage, Version=4.3.2.0, Culture=neutral, PublicKeyToken=null'.

使用System.Net.Http关注此discussion并安装kpm包后，我开始收到新错误：

An unhandled exception occurred while processing the request.NullReferenceException: Object reference not set to an instance of an object
Microsoft.WindowsAzure.Storage.Shared.Protocol.HttpClientFactory.BuildHttpClient[TableResult] (Microsoft.WindowsAzure.Storage.Core.Executor.RESTCommand`1 cmd, System.Net.Http.HttpMessageHandler handler, Boolean useVersionHeader, Microsoft.WindowsAzure.Storage.OperationContext operationContext) [0x00000] in <filename unknown>, line 0

注意：我在System.Net.Http中安装了"aspnetcore50": { "dependencies": { ... } }软件包，但似乎必须将其安装在公共dependencies

中

知道为什么会发生这种情况以及如何解决它？

Answer 1

您无法在aspnetcore50下使用Azure Storage .NET客户端，它不适用于此运行时。您需要将其提取到aspnet50（现在为dnx451）。

使用ASP.NET vNext在Mac上使用Azure存储
