用于将nativs dll部署到输出目录的目标文件

Question

我有一个具有以下结构的小部件：

Lib
  -> net45
    -> MyDll.dll
Runtimes
  -> win10-x64
    -> native
      dependency1.dll
      dependency2.dll
      dependency3.dll

我将此nuget添加到我的一个项目中。每当我构建该项目时，我都希望将所有dll复制到输出目录中。但是，只会复制“ MyDll.dll”，而不会复制本机“运行时”文件夹中的所有dll。我看过这篇文章，解释了如何使用.targets文件来完成此操作：Add native files from NuGet package to project output directory。但是，我找不到有关如何添加.targets文件的具体信息，并且该文章已有6年的历史。现在肯定有新的更好的东西吗？

基本上，将本机dll复制到构建的输出目录的最佳方法是什么？

Answer 1

这实际上取决于您的客户项目是本地项目还是托管项目。

如果您的项目是本机项目，则需要执行以下操作：

0）假设我们具有以下结构：

bin
• Win32
  • yourlibrary.lib
  • yourlibrary.dll
• x64
• yourlibrary.lib
• yourlibrary.dll

包括

yourlib.h

YourPackage.nuspec

YourPackage.targets

1）YourPackage.nuspec文件包含以下内容：

<?xml version="1.0"?>
<package >
  <metadata>
    <id>YourPackage</id>
    <version>1.0.0.0</version>
    <title>Your Packaged Software</title>
    <authors>your name</authors>
    <owners>your name</owners>
    <iconUrl>link to icon</iconUrl>
    <requireLicenseAcceptance>false</requireLicenseAcceptance>
    <description>Description for your package</description>
    <releaseNotes>Fixed that, added this</releaseNotes>
    <copyright>Copyright by you</copyright>
    <tags>native yourpackage library</tags>
  </metadata>
  <files>
    <!-- .targets file that should be included in the dependee project automatically by Nuget -->
    <file src="YourPackage.targets" target="\build\native\YourPackage.targets" />

    <!-- Include header files for development -->
    <file src="include\**" target="\lib\native\include" />

    <!-- Binaries -->
    <file src="bin\**" target="\lib\native\bin" />
  </files>
</package>

2）然后添加.target文件：
<?xml version="1.0" encoding="utf-8"?>
<Project ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003" >
  <ItemDefinitionGroup>
    <!-- COMPILATION -->
    <!-- header files (.h) that should be copied  -->
    <ClCompile>
      <AdditionalIncludeDirectories>$(MSBuildThisFileDirectory)..\..\lib\native\include\;%(AdditionalIncludeDirectories)</AdditionalIncludeDirectories>
      <!-- This is just for the convinience, so you can check within C++ code if the package is used, i.e.: #ifdef HAS_YOUR_PACKAGE -->
      <PreprocessorDefinitions>HAS_YOUR_PACKAGE;%(PreprocessorDefinitions)</PreprocessorDefinitions>
    </ClCompile>
  </ItemDefinitionGroup>

  <!-- LINKING -->
  <!-- Add static/import library for linking -->
  <ItemDefinitionGroup>
    <Link>
      <AdditionalLibraryDirectories>$(MSBuildThisFileDirectory)..\..\lib\native\bin\$(Platform)\;%(AdditionalLibraryDirectories)</AdditionalLibraryDirectories>
      <AdditionalDependencies>yourlibrary.lib;%(AdditionalDependencies)</AdditionalDependencies>
    </Link>
  </ItemDefinitionGroup>

  <!-- DEPLOYMENT -->
  <!-- Copy dlls to $(OutDir) -->
  <ItemGroup>
    <NativeLibs Include="$(MSBuildThisFileDirectory)..\..\lib\native\bin\$(Platform)\*.dll" />
    <None Include="@(NativeLibs)">
      <Link>%(FileName)%(Extension)</Link>
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
    </None>
  </ItemGroup>     
</Project>

3）完成所有操作后，在程序包目录中运行：nuget pack YourPackage.nuspec这将创建一个新的nuget程序包，该程序包在本机项目中使用后应该可以工作。
重要提示：这对我有用，但是有时在VS中加载客户端项目失败。
