Question

我使用.NET Core RC2编写了一个库，现在我将其更新为RTM。除了一个，迁移中没有问题。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：

类型＆＃39; GuidAttribute＆＃39;存在于两者中＆＃39; System.Runtime.InteropServices.PInvoke，Version = 4.0.0.0， Culture = neutral，PublicKeyToken = b03f5f7f11d50a3a＆＃39;和＆＃39; System.Runtime.InteropServices，Version = 4.1.0.0

我不确定这里发生了什么。

这就是我的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")]

它都是通用的，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会产生误导。我做的是否有任何错误，但无法看到？我该怎么调试呢？

Answer 1

.Net Core开发过程中存在库System.Runtime.InteropServices.PInvoke，GuidAttribute类型被移动到它。但是this library was removed before the 1.0 version。

问题在于AWSSDK.Core 3.2.4.1-beta取决于它。

我认为解决此问题的最佳方法是升级到AWSSDK.Core和AWSSDK.EC2 3.2.5-beta，它依赖于1.0版本的.Net标准库，因此它们没有这个问题。

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