WCF 和客户端应用程序中的不明确引用 [英] Ambiguous reference in WCF and client application

问题描述

我设法在一个测试项目中重现了一个错误，其结构与我的生产代码相似.它由三个简单的项目组成:

I've managed to reproduce one of the errors in a test project with a similar structure to my production code. It consists of three simple projects:

通用(类库):

namespace Common
{
    public enum PrimaryColor
    {
        Red,
        Green,
        Blue
    };
}

Library(WCF 服务库)，其中引用了 Common:

Library (WCF service library), which has a reference to Common:

using Common;

namespace Library
{
    [ServiceContract]
    public interface ILibrary
    {
        [OperationContract]
        PrimaryColor GetColor();
    }

    public class Library : ILibrary
    {
        public PrimaryColor GetColor()
        {
            return PrimaryColor.Red;
        }
    }
}

ClientApp(控制台应用程序)，它具有对 Common 的引用，以及对名为LibraryServiceReference"的库的服务引用:

ClientApp (console application), which has a reference to Common, and a service reference to Library called "LibraryServiceReference":

using Common;
using ClientApp.LibraryServiceReference;

namespace ClientApp
{
    class Program
    {
        static void Main(string[] args)
        {
            LibraryClient client = new LibraryClient("WSHttpBinding_ILibrary");
            PrimaryColor color = client.GetColor();
        }
    }
}

ClientApp 和 Library 中的 app.config 文件是自动生成的，我没有修改它们，也没有更改 ClientApp 中 LibraryServiceReference 的默认配置.

The app.config files in ClientApp and Library are auto-generated and I have not modified them, and I have not changed the default configuration for the LibraryServiceReference in ClientApp.

当我编译此解决方案时，我在 ClientApp 项目中收到以下错误:

When I compile this solution, I get the following errors in the ClientApp project:

错误 1

'PrimaryColor' is an ambiguous reference between 'Common.PrimaryColor' and 'ClientApp.LibraryServiceReference.PrimaryColor'

错误 2

Cannot implicitly convert type 'ClientApp.LibraryServiceReference.PrimaryColor' to 'Common.PrimaryColor'. An explicit conversion exists (are you missing a cast?)

请帮我解决这个问题.

推荐答案

确保在高级选项中选择在所有引用的程序集中重用类型strong>添加服务引用或配置服务引用.

Make sure that 'Reuse types in all referenced assemblies' is selected in the Advanced options of Add service reference or Configure Service Reference.
