그래서 나는이 같은 문제에 부딪쳤다. 문제를 "수정"하지 않는다는 것을 알았 기 때문에 DefaultCompileItems를 끄고 싶지 않았습니다. 그래서 프로젝트를 언로드하고 Visual Studio에서 텍스트 모드로 .csproj 파일을 열어서 이것을 보았습니다.

<ItemGroup>
    <Content Include="wwwroot\css\custom-bootstrap-navbar.css" />
    <Content Include="wwwroot\images\friends-eating\image1.jpg" />
    <Content Include="wwwroot\images\friends-eating\image2.jpg" />
    <Content Include="wwwroot\images\friends-eating\image3.jpg" />
</ItemGroup>
<ItemGroup>
    <Folder Include="wwwroot\images\friends-eating\" />
</ItemGroup>

첫 번째 ItemGroup 블록을 주석 처리했을 때 작동했습니다. 내가 생각하는 것은 프로젝트가 전체 \ images \ friends-eating \ 폴더를 추가 한 다음 각 개별 이미지를 추가하여 중복을 일으키는 것입니다.

As far as the custom css and js, the project automatically adds wwwroot\css and wwwroot\js so if you have an individual file added (like wwwroot\css\custom-bootstrap-navbar.css) it'll count as a duplicate.

1. Click 'Show All Files' in Solution Explorer
2. Right-click over 'wwwroot' select 'Exclude From Project'
3. Right-click over 'wwwroot' select 'Include in Project'

This worked in my case:

 <PropertyGroup>
    ...
    <EnableDefaultContentItems>false</EnableDefaultContentItems>
  </PropertyGroup>

---

It happend when I upgrade my project from .NET Core 1.X to 2.0 just now. Here is my solution.

• Open xxx.csproj, or right click project
• Unload Project
• Edit xxx.csproj.

Then remove ItemGroup items start with <Content Include = "wwwroot\xxxxx"

---

My issues was close but not the exact same. My error was this:

C:\Program Files\dotnet\sdk\2.0.0-preview2-006497\Sdks\Microsoft.NET.Sdk\build\Microsoft.NET.Sdk.DefaultItems.targets(285,5): error : Duplicate 'Content' items were included. The .NET SDK includes 'Content' items from your project directory by default. You can either remove these items from your project file, or set the 'EnableDefaultContentItems' property to 'false' if you want to explicitly include them in your project file. For more information, see https://aka.ms/sdkimplicititems. The duplicate items were: 'wwwroot\js\KOBindings.js'; 'wwwroot\js\KOPleaseWait.js'; 'wwwroot\js\ProjectTime\Add.js'; 'wwwroot\js\TimeAdmin\Invoice.js'; 'wwwroot\js\TimeAdmin\PayPeriodTotals.js' [C:\Avantia Projects\Time Card\avantia-timesheet\Solution\Almanac\Almanac.csproj]

If I did this:

<EnableDefaultContentItems>false</EnableDefaultContentItems>

It would not compile as all of the sudden Areas would not be recognized.

My solution, seems odd, but the message is telling me so, there were duplicate files:

The duplicate items were: 'wwwroot\js\KOBindings.js'; 'wwwroot\js\KOPleaseWait.js'; 'wwwroot\js\ProjectTime\Add.js'; 'wwwroot\js\TimeAdmin\Invoice.js'; 'wwwroot\js\TimeAdmin\PayPeriodTotals.js'

Looking at my .csproj file:

<ItemGroup>
  <Content Include="pdf.js" />
  <Content Include="wwwroot\js\package.json" />
  <Content Include="wwwroot\js\pdf.js" />
  <Content Include="wwwroot\js\KOBindings.js" />
  <Content Include="wwwroot\js\KOPleaseWait.js" />
  <Content Include="wwwroot\js\ProjectTime\Add.js" />
  <Content Include="wwwroot\js\TimeAdmin\Invoice.js" />
  <Content Include="wwwroot\js\TimeAdmin\PayPeriodTotals.js" />
</ItemGroup>

This was the ONLY location within the entire project where these files were references (aside from where they were loaded.) So the phrase duplicate does not make any sense to me. However, commenting those files out as such, took care of my problem:

<ItemGroup>
  <Content Include="pdf.js" />
  <Content Include="wwwroot\js\package.json" />
  <Content Include="wwwroot\js\pdf.js" />
  <!--
    <Content Include="wwwroot\js\KOBindings.js" />
    <Content Include="wwwroot\js\KOPleaseWait.js" />
    <Content Include="wwwroot\js\ProjectTime\Add.js" />
    <Content Include="wwwroot\js\TimeAdmin\Invoice.js" />
    <Content Include="wwwroot\js\TimeAdmin\PayPeriodTotals.js" />
  -->
</ItemGroup>

I assume this has something to do with the 2.0.0-preview2-006497 that I recently installed.

Also, this link mentions talks about globs. But does not tell me where that is. It talks about SDKs and such. Yet the answer was my custom .js files. That link needs to be updated or expanded on IMHO. Hope this helps someone.

As link says, you can disable this behavior (auto-include) and include all content explicitly by adding this into your csproj file:

<PropertyGroup>
    <EnableDefaultContentItems>false</EnableDefaultContentItems>
</PropertyGroup>

---

In my case, I solved this by deleting all files from the wwwroot-Directory in VS. Unload and reload the Project. Copy all files back in with VS. Done

---

Actually, Asp.net core automatically include content from wwwroot\css\ , wwwroot\js\ and wwwroot\lib\ location, so despite this if your csproj file explicitly include content from those directories then those content will be duplicated so removing content from you csproj file is the better way to get rid of this error. So remove below content-

  <ItemGroup>
    <Compile Remove="wwwroot\lib\jquery-validation\**" />
    <Content Remove="wwwroot\lib\jquery-validation\**" />
    <EmbeddedResource Remove="wwwroot\lib\jquery-validation\**" />
    <None Remove="wwwroot\lib\jquery-validation\**" />   
 </ItemGroup>

  <ItemGroup>
    <Content Include="wwwroot\css\BasicQuotation.css" />
    <Content Include="wwwroot\js\BasicQuotation.js" />   
  </ItemGroup>

---

Not that I can see it in your example above, to help other SO searchers..

You can also get this error when you have the same file listed twice in <Content Include="xxx" /> elements in your csproj file.

Remove the duplicate and rebuild.

---

Under Visual Studio 2017 15.3, with .NET Core 2.0, EnableDefaultCompileItems did not work for me.

I needed to add this to my .csproj

  <PropertyGroup>
    <EnableDefaultContentItems>false</EnableDefaultContentItems>
  </PropertyGroup>

---

I found a different proper solution.

1. Right click on your mvc project and click Edit csproj.
2. If you are adding files under wwwroot, just move them to a folder under wwwroot, let's say it "theme"

And delete all content tags in csproj file if their exists, an example;

<Content Include="wwwroot\theme\favicon.ico" />
<Content Include="wwwroot\theme\fonts\cyrillic-ext400.woff2" />
<Content Include="wwwroot\theme\fonts\cyrillic-ext700.woff2" />

And only add this;

  <ItemGroup>
    <Folder Include="wwwroot\theme\" />
  </ItemGroup>

So, csproj file should be look like this;

    <Project Sdk="Microsoft.NET.Sdk.Web">

      <PropertyGroup>
        <TargetFramework>netcoreapp1.1</TargetFramework>
      </PropertyGroup>

      <PropertyGroup>
        <PackageTargetFallback>$(PackageTargetFallback);portable-net45+win8+wp8+wpa81;</PackageTargetFallback>
      </PropertyGroup>

      <ItemGroup>
        <Folder Include="wwwroot\theme\" />
      </ItemGroup>
      <ItemGroup>
        <PackageReference Include="Microsoft.ApplicationInsights.AspNetCore" Version="2.0.0" />
...

With that way, I think you are adding all files under theme folder. So not include them one by one which occours some erros.

.NET Core Projects

If you are in a class library, probably you'll need to remove all Compile/Content elements from your csproj as those are included automatically.

<Project Sdk="Microsoft.NET.Sdk">    
  <PropertyGroup>
    <TargetFramework>netcoreapp2.0</TargetFramework>
  </PropertyGroup>
  <!-- NEEDED -->
  <ItemGroup>
    <ProjectReference />
    <ProjectReference />
  </ItemGroup>
  <!-- NOT NEEDED -->
  <ItemGroup>
   <Compile Include="Models\ExampleClass.cs" />
   <Content ... />
  </ItemGroup>
</Project>

---

My case I is disable both below default items.

<EnableDefaultContentItems>false</EnableDefaultContentItems>
<EnableDefaultItems>false</EnableDefaultItems>

---

Excluding and Including back the folders that have duplicates error worked for me! Hope this helps someone else!

---

I think what disabling "EnableDefaultContentItems" isn't the best option. Manual cs-Proj file editing also isn't the good idea at all.

So for our build server pipeline, we wrote very small tool what will remove all duplicated entries automatically: dotnet-csproj-cleaner

We run it under Docker as the first build step in our continuous integration pipeline.

I had the same problem with only a file, and all others were working (all my templates were stored directly in wwwroot/content). The project was not created by me so I don't know many details.

The problem was fixed by renaming back and forth the file with the issue:

MyTemplate.html -- renamed --> MyTemplate2.html -- renamed --> MyTemplate.html

Note: At the first rename I got an error with something along the lines of "content configuration not found", but the second rename worked without issues.

After this I was able to compile the project successfully.
