点网核心和Azure存储:无法加载文件或程序集系统，版本= 4.0.0.0 [英] Dot Net Core and Azure Storage: Could not load file or assembly System, Version=4.0.0.0
问题描述
我有一个运行在"netcoreapp1.0"上的Web API，该API正在使用Azure存储客户端.访问blob根本没有问题，但是当我尝试对表执行任何操作时，都会引发此错误:
I have a web API running on "netcoreapp1.0" which is using Azure Storage Client. Accessing blobs has no issue at all but when I try execute any operation with tables it throws me this error:
抛出异常:System.Private.CoreLib.ni.dll中的'Microsoft.WindowsAzure.Storage.StorageException'
Exception thrown: 'Microsoft.WindowsAzure.Storage.StorageException' in System.Private.CoreLib.ni.dll
其他信息:无法加载文件或程序集'System，Version = 4.0.0.0，Culture = neutral，PublicKeyToken = b77a5c561934e089'.系统找不到指定的文件.
Additional information: Could not load file or assembly 'System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'. The system cannot find the file specified.
发生的具体行如下:
如果(等待table.ExistsAsync())
if (await table.ExistsAsync())
即使将其删除，只要它碰到实际上会对Azure进行HTTP调用的行，它仍然会产生相同的结果.我正在导入"net46"，并且我也尝试在project.json中导入"net40"，但是没有任何变化.
Even removing this, whenever it hits a line where it would actually do a HTTP call to Azure it still results the same. I am importing "net46", and I have tried also importing in my project.json "net40", but no change.
上面的代码位于"Cameo.Azure.Storage.Library"中.它以netstandard1.6为目标，并引用"WindowsAzure.Storage":"7.2.0"和"NETStandard.Library":"1.6.0".
The code above is living in "Cameo.Azure.Storage.Library". It is targeting netstandard1.6 and it is referencing "WindowsAzure.Storage": "7.2.0" and "NETStandard.Library": "1.6.0".
我的project.json在下面:
My project.json is below:

推荐答案
将Web API中的project.json更改为此已解决.
Changing the project.json in web API to this has solved the issue.
"frameworks": {
"netcoreapp1.0": {
"imports": [
"portable-net45+win8"
]
}
}
您只能导入框架的核心或便携式(PCL)版本.参考:
You can only import core or portable (PCL) version of the framework. Reference:
