csproj中的错误 - 重复项目

Question

我有Visual Studio 2010的错误:

错误1在"Sources"参数中多次指定"CrossDomainService.svc.cs"项."Sources"参数不支持重复项.WcfServiceDomain

并从msbuild

C:\ Windows\Microsoft.NET\Framework\v4.0.30319\Microsoft.CSharp.targets(160,9):错误MSB3105:"Sources"参数中指定的项目"CrossDomainService.svc.cs"超过了oce ."Sources"参数不支持重复项.[C:\ inetpub\Wwwroot\axaptaWcfConnection\WcfServiceDomain\WcfSer viceDomain.csproj]

我的文件是csproj:

我没有看到任何重复:/这个错误的任何想法？

Answer 1

我在我的解决方案中面临同样的问题,其中一个源文件存在相同的错误,

我修好了如下,

1. 检查给出错误的文件名.

2. 找出包含文件的项目.

3. 打开该特定项目的.csproj文件(该文件可以在放置解决方案的目录中找到).

4. 搜索.csproj文件中引发错误的文件名.

5. 你会发现该行的两个条目,如

 <Compile Include="duplicate.aspx.cs">
      <SubType>ASPXCodeBehind</SubType>
      <DependentUpon>Duplicate.aspx</DependentUpon>
    </Compile>


 <Compile Include="duplicate.aspx.cs">
      <SubType>ASPXCodeBehind</SubType>
      <DependentUpon>Duplicate.aspx</DependentUpon>
    </Compile>

1. 从其中一行中删除任意一行.

2. 保存更改.

3. 重新加载项目,你的错误肯定已经消失.

Answer 2

对于遇到相同问题的人,没有任何帮助他们,他们不想重新创建项目:尝试删除YourPojectName.csproj.user文件.它帮助了我.我之前手动修改了.csproj,并且引入了修改(不知何故)可能与这两个文件存在一些差异.

Answer 3

唯一的解决方案是重新创建项目：/
