AssemblyInfo.cs 中的 GuidAttribute 错误

GuidAttribute error in AssemblyInfo.cs

我使用 .NET Core RC2 编写了一个库,现在我正在将它更新为 RTM。除了一个问题外,迁移没有任何问题。出于某种原因,Visual Studio(以及 dotnet 实用程序)在 AssemblyInfo.cs:

中引发有关 Guid 的错误

The type 'GuidAttribute' exists in both 'System.Runtime.InteropServices.PInvoke, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' and 'System.Runtime.InteropServices, Version=4.1.0.0

我不确定这里发生了什么。

这是我的 AssemblyInfo.cs 的样子:

using System.Reflection;
using System.Runtime.CompilerServices;
using System.Runtime.InteropServices;

// General Information about an assembly is controlled through the following
// set of attributes. Change these attribute values to modify the information
// associated with an assembly.
[assembly: AssemblyConfiguration("")]
[assembly: AssemblyCompany("")]
[assembly: AssemblyProduct("My.Library")]
[assembly: AssemblyTrademark("")]

// Setting ComVisible to false makes the types in this assembly not visible
// to COM components.  If you need to access a type in this assembly from
// COM, set the ComVisible attribute to true on that type.
[assembly: ComVisible(false)]

// The following GUID is for the ID of the typelib if this project is exposed to COM
[assembly: Guid("f89c2fd8-91f3-4f5a-87b6-094ee19712cf")]

都是通用的,由Visual Studio生成。

我的project.json也很简单:

{
  "title": "My Library",
  "version": "1.0.0-*",
  "dependencies": {
    "NETStandard.Library": "1.6.0",
    "AWSSDK.Core": "3.2.4.1-beta",
    "AWSSDK.EC2": "3.2.4.1-beta",
    "System.Net.Primitives": "4.0.11",
    "System.Threading.Tasks": "4.0.11",
    "System.Collections": "4.0.11"
  },
  "frameworks": {
    "netstandard1.5": {
      "imports": [ "dnxcore50", "portable-net45+win8" ]
    }
  },
  "buildOptions": {
    "xmlDoc": true
  }
}

我真的不确定发生了什么,我开始认为这个错误可能具有误导性。我犯了什么错误但看不到吗?我该如何调试?

库System.Runtime.InteropServices.PInvoke在.Net Core的开发过程中存在,GuidAttribute类型被移至其中。但是 this library was removed before the 1.0 version.

问题是 AWSSDK.Core 3.2.4.1-beta 依赖它。

我认为解决这个问题的最好方法是升级到 AWSSDK.Core 和 AWSSDK.EC2 3.2.5-beta,它们依赖于 .Net Standard 库的 1.0 版本,所以他们没有这个问题。

另一种可能的解决方案是从您的代码中删除 GuidAttribute(或将其隐藏在 #if 后面),因为您很可能不需要它。
