Visual Studio 2017 csproj .NET Core构建 - 未正确复制视图

时间:2017-03-20 16:59:22

标签: visual-studio msbuild asp.net-core-mvc .net-core visual-studio-2017

我有一个在.NET Core中运行的项目,我使用VS2017作为IDE。

当我通过Visual Studio 2017构建项目时,它不会自动将Views文件夹和wwwroot文件夹添加到[projectRoot]/bin/Debug/netcoreapp1.1/win10-x64BuildDir)的输出中。这意味着,如果我尝试直接从bin文件夹中创建的.exe file运行我的网站,则会收到错误的viewswwwroot错误。如果我手动将这些文件夹复制到BuildDir,则视图会正确加载。

我可以在我的.csproj文件中设置以下内容:

<Content Update="Views\**">
  <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
</Content>

然后Views工作,但现在我的布局文件没有被编译,所以我得到以下内容:

<head>
    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>@ViewData["Title"] - FirstAgenda</title>

    <environment names="Development">
        <link rel="stylesheet" href="~/lib/bootstrap/dist/css/bootstrap.css" />
        <link rel="stylesheet" href="~/css/site.css"/>
        <link rel="stylesheet" href="~/css/overwrite.css" asp-append-version="true" />
    </environment>
    <environment names="Staging,Production">
        <link rel="stylesheet" href="https://ajax.aspnetcdn.com/ajax/bootstrap/3.3.6/css/bootstrap.min.css"
              asp-fallback-href="~/lib/bootstrap/dist/css/bootstrap.min.css"
              asp-fallback-test-class="sr-only" asp-fallback-test-property="position" asp-fallback-test-value="absolute" />
        <link rel="stylesheet" href="~/css/site.min.css" asp-append-version="true" />
        <link rel="stylesheet" href="~/css/overwrite.css" asp-append-version="true" />
    </environment>
</head>

这意味着我的根文件夹未正确定位。还有点告诉我,只是将文件复制到输出目录是不正确的。

如果我发布我的应用程序(也没有添加到.csproj文件),以上所有工作都有效。我只有一个项目运行器,我希望能够指向我的网站可执行文件的调试版本,因为与仅使用VS2017构建项目相比,很容易忘记进行发布。

我只是不知道从哪里开始,任何帮助都会受到赞赏?

添加了精简版csproj(不起作用):

还尝试使用dotnet new mvc

创建新项目

它也不起作用。

我的dotnet核心cli版本是[1.0.1]。

修改

我按照你概述的步骤进行操作。我还尝试使用dotnet new mvc创建一个新项目并按照您的步骤操作。两者都给了我同样的错误。它无法找到appsettings.json。如果我然后在.csproj中添加propertygroup。这告诉msbuild将appsettings.json和web.config复制到输出

<ItemGroup>
  <Content Update="appsettings.json;web.config">
    <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
  </Content>
</ItemGroup>

然后我可以通过exe启动程序,但是当我访问索引时,当我尝试访问其中一个视图时它会给我:

Microsoft.AspNetCore.Diagnostics.DeveloperExceptionPageMiddleware[0]
    An unhandled exception has occurred while executing the request
    System.InvalidOperationException: The view 'Index' was not found. The following locations were searched:
  /Views/Home/Index.cshtml
  /Views/Shared/Index.cshtml

更新

Shaun Lutins的回答似乎对我有用。两者都有构建和发布选项。唯一的问题是我收到了错误:

Duplicate 'Content' items were included. The .NET SDK includes 'Content' items from your project directory by default.

但是通过更改以下内容解决了这个问题:

<ItemGroup>                                                                            
   <Content Include="appsettings.json" CopyToOutputDirectory="Always" />
   <Content Include="Views\**\*" CopyToOutputDirectory="Always" />
   <Content Include="wwwroot\**\*" CopyToOutputDirectory="Always" />
</ItemGroup>      

<ItemGroup>                                                                            
   <Content Update="appsettings.json;web.config" CopyToOutputDirectory="PreserveNewest"/>
   <Content Update="Views\**\*" CopyToOutputDirectory="PreserveNewest" />
   <Content Update="wwwroot\**\*" CopyToOutputDirectory="PreserveNewest" />
</ItemGroup>      

2 个答案:

答案 0 :(得分:6)

我所解释的挑战是来运行dotnet build并能够从任何地方执行已编译的EXE。答案需要两个步骤:

  1. 将所需内容复制到bin中,
  2. 相对于bin设置ContentRoot和WebRoot。
  3. 首先,修改csproj以将所需内容复制到bin。开箱即用,dotnet build不会将Views,appsettings.json或wwwroot复制到bin。因此,我们需要明确指定CopyToOutputDirectory;为此,我们还需要将EnableDefaultContentItems设置为false,否则我们的显式设置将复制默认内容项设置。

    其次,修改Program.cs以指定新的ContentRoot和WebRoot。开箱即用,Program.cs设置UseContentRoot(Directory.GetCurrentDirectory())。对于我们的情况有问题,当前目录是我们运行可执行文件的目录。因此,如果我们从桌面的命令行运行EXE,那么当前目录将是C:/Users/MyUser/Desktop。该应用程序将找不到Views,appsettings.json和其他内容。

    以下是我用来解决挑战的一些工作步骤。

    工作步​​骤

    1. cd C:\temp
    2. dotnet new mvc
    3. 使用&#34; Working csproj&#34;更新temp.csproj。 XML。
    4. 使用&#34; Working Program.cs&#34;更新Program.cs。代码。
    5. dotnet restore
    6. dotnet build
    7. cd ..
    8. 任何地方,运行C:\temp\bin\Debug\netcoreapp1.0\win10-x64\temp.exe
    9. 工作csproj

答案 1 :(得分:0)

我已将此问题发布到GitHub上的ASP.NET Core repo: https://github.com/aspnet/Home/issues/2897

虽然接受的答案有效,但感觉有点像黑客。

它也存在问题。当有大量要复制的文件时,构建过程很慢,并且构建过程不会删除已删除的文件。

接受的答案也是对EnableDefaultContentItems设置的误用。

因此,虽然我很高兴有一个短期解决方案,但需要寻求长期解决问题的方法。

希望我在GitHub上提出的这个问题将会为更加永久的解决方案而努力。
