将内容和编译文件从nuget复制到.net核心项目

• 问答

我正在尝试创建一个包含类和xsd文件的多目标框架nuget。类文件是从xml模式定义文件生成的，并在开发过程中使用。然后在运行时使用xsd来验证序列化的类输出。

由于nuget需要是多目标框架，因此已选择.net标准lib项目，因此将xsd导入到与生成的类文件相同的项目中。我正在使用Visual Studio 2019环境，并想使用pack选项。

我面临的问题是，每当我在nuget中指定cs和xsd文件是不同的buildaction类型时，使用nuget的项目中就不包括xsd。如果我指定cs和xsd文件都来自同一buildaction类型，则全部包含在内。

但是，如果将CS文件定义为buildaction“ None”或“ Content”，则不能在使用Nuget的项目中使用它们。仅当您指定cs文件来自buildaction类型“ Compile”时，才可以使用它们。 xsd文件不能来自“编译”类型，因为这将导致安装Nuget时出错。

我已经检查了文件是否存在于nuget中。它们也在创建的.nuspec文件中指定，并放在nuget中。在将nuget安装到项目中之后，它们还将出现在obj \ projects.assets.json文件中。我看不到任何错误或警告。

我在某处读到，因为nuget是通过.net核心项目的参考打包的，所以内容不会始终显示设计时，但必须在运行时。有趣的是，xsd始终丢失，而从不包含cs文件。而且在运行时也看不到xml文件。

我已经更改了csproj文件，使其支持多目标框架，并且我添加了不将创建的dll添加到nuget包中的选项。

 <PropertyGroup>
    <TargetFrameworks>netstandard2.0;netcoreapp2.1;net45</TargetFrameworks>
    <Version>1.0.30</Version>
  </PropertyGroup>
  <PropertyGroup>
    <IncludeBuildOutput>false</IncludeBuildOutput>
  </PropertyGroup>

要将内容复制到nuget中，我添加了以下几行：

<ItemGroup>
    <Content Include="XSD/**/*.xsd" copyToOutput="true">
      <IncludeInPackage>true</IncludeInPackage>
      <CopyToOutput>true</CopyToOutput>
      <buildaction>Content</buildaction>
      <copyToOutput>true</copyToOutput>
      <CopyToOutputDirectory>Always</CopyToOutputDirectory>
    </Content>
  </ItemGroup>

  <ItemGroup>
    <Content Include="Messages.Voorbeeld/**/*.cs" copyToOutput="true">
      <IncludeInPackage>true</IncludeInPackage>
      <CopyToOutput>true</CopyToOutput>
      <buildaction>Compile</buildaction>
      <copyToOutput>true</copyToOutput>
      <CopyToOutputDirectory>Always</CopyToOutputDirectory>
    </Content>
  </ItemGroup>

nuget包中的nuspec文件如下所示：

它一定很小，但我找不到。谁可以帮助我？

iCMS 回答：将内容和编译文件从nuget复制到.net核心项目

通过将cs文件的BuildAction属性从“ Compile”更改为“ C＃Compiler”，解决了该问题。如果正确，我不确定。

这样做，生成的nuspec文件不再具有用于CS文件的buildAction，但仍使用BuildAction =“ Compile”创建json文件。

现在，带有文件的目录都显示在Visual Studio中，并且CS文件已编译且可用。
