asp.net - 在 Mac 上使用 Azure 存储与 ASP.NET vNext

Question

尝试从 Mac 上的 MVC 6 应用程序中的 Azure TableStorage 读取数据。 它可以在 PC 上运行，但在 Mac 上时会出现此错误:

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'.

遵循此discussion后并安装System.Net.Http包使用 kpm我开始收到一个新错误:

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: 我有System.Net.Http软件包安装在 "aspnetcore50": { "dependencies": { ... } } ，但似乎必须安装在公共(public) dependencies 中

知道为什么会发生这种情况以及如何解决它吗？

Answer 1

您无法在 aspnetcore50 下使用 Azure 存储 .NET 客户端，它不适用于此运行时。您需要将其拉到 aspnet50 下(现在 dnx451)。
