如何让nuget（powershell）在目标csproj文件中插入<dependentupon>元素</dependentupon>

Question

我正在为一个Windows服务编写一个nuget包，我的想法是我的同事可以创建一个Windows服务安装包，并为他们设置所有默认的日志记录设置，entlib库和其他的house keep任务

除了一件令我疯狂的事情外，我已经完成了一切工作。

在我的nuget目录的content文件夹中，我有Service.cs和Service.Designer.cs这些被添加到目标csproj但它们没有相关。

当我查看csproj文件时，我看到：

<Compile Include="Service.cs">
  <SubType>Component</SubType>
</Compile>
<Compile Include="Service.Designer.cs" />

但我希望看到：

<Compile Include="Service.cs">
  <SubType>Component</SubType>
</Compile>
<Compile Include="Service.Designer.cs">
  <DependentUpon>Service.cs</DependentUpon>
</Compile>

任何想法，非常确定它会涉及install.ps脚本，但我的powershell技能是不存在的？

顺便说一下，可以用nuget来删除/覆盖文件吗？到目前为止它似乎只是跳过了。

经过2天左右的powershell和msbuild，我终于得到了一个有效的解决方案。见下文。调用project.Save（）的警告是至关重要的 - 如果没有这个，你将得到一个“检测到冲突的文件修改”警告。如果你先调用project.Save（），那么只要你完成就会被要求重新加载解决方案。

param($installPath, $toolsPath, $package, $project)

#save the project file first - this commits the changes made by nuget before this     script runs.
$project.Save()

#Load the csproj file into an xml object
$xml = [XML] (gc $project.FullName)

#grab the namespace from the project element so your xpath works.
$nsmgr = New-Object System.Xml.XmlNamespaceManager -ArgumentList $xml.NameTable
$nsmgr.AddNamespace('a',$xml.Project.GetAttribute("xmlns"))

#link the service designer to the service.cs
$node = $xml.Project.SelectSingleNode("//a:Compile[@Include='Service.Designer.cs']", $nsmgr)
$depUpon = $xml.CreateElement("DependentUpon", $xml.Project.GetAttribute("xmlns"))
$depUpon.InnerXml = "Service.cs"
$node.AppendChild($depUpon)

#link the settings file to the settings.designer.cs 
$settings = $xml.Project.SelectSingleNode("//a:None[@Include='ServiceSettings.settings']", $nsmgr)
$generator = $xml.CreateElement("Generator", $xml.Project.GetAttribute("xmlns"))
$generator.InnerXml = "SettingsSingleFileGenerator"
$settings.AppendChild($generator)

$LastGenOutput = $xml.CreateElement("LastGenOutput", $xml.Project.GetAttribute("xmlns"))
$LastGenOutput.InnerXml = "ServiceSettings.Designer.cs"
$settings.AppendChild($LastGenOutput)

#set the settings designer to be autogen
$settingsDesigner = $xml.Project.SelectSingleNode("//a:Compile[@Include='ServiceSettings.Designer.cs']", $nsmgr)
$autoGen = $xml.CreateElement("AutoGen", $xml.Project.GetAttribute("xmlns"))
$autoGen.InnerXml = "True"

$DesignTimeSharedInput = $xml.CreateElement("DesignTimeSharedInput", $xml.Project.GetAttribute("xmlns"))
$DesignTimeSharedInput.InnerXml = "True"

$AGDependentUpon = $xml.CreateElement("DependentUpon", $xml.Project.GetAttribute("xmlns"))
$AGDependentUpon.InnerXml = "ServiceSettings.settings"

$settingsDesigner.AppendChild($autoGen)
$settingsDesigner.AppendChild($DesignTimeSharedInput)
$settingsDesigner.AppendChild($AGDependentUpon)

#fix up the project installer.    
$projectInstallerRes = $xml.Project.SelectSingleNode("//a:EmbeddedResource[@Include='ProjectInstaller.resx']", $nsmgr)
$projectInstallerResDepUpon = $xml.CreateElement("DependentUpon", $xml.Project.GetAttribute("xmlns"))
$projectInstallerResDepUpon.InnerXml = "ProjectInstaller.cs"
$projectInstallerRes.AppendChild($projectInstallerResDepUpon)

$projectInstallerDesigner = $xml.Project.SelectSingleNode("//a:Compile[@Include='ProjectInstaller.Designer.cs']", $nsmgr)
$projectInstallerDesignerDepUpon = $xml.CreateElement("DependentUpon", $xml.Project.GetAttribute("xmlns"))
$projectInstallerDesignerDepUpon.InnerXml = "ProjectInstaller.cs"
$projectInstallerDesigner.AppendChild($projectInstallerDesignerDepUpon)

#delete the bundled program.cs file.
$prog = $xml.Project.SelectSingleNode("//a:Compile[@Include='Program.cs']", $nsmgr)
$prog.SelectSingleNode("..").RemoveChild($prog)

#delete the bundled service1 file
$oldServiceFile = $xml.Project.SelectSingleNode("//a:Compile[@Include='Service1.cs']", $nsmgr)
$oldServiceFile.SelectSingleNode("..").RemoveChild($oldServiceFile)

$oldServiceDesignerFile = $xml.Project.SelectSingleNode("//a:Compile[@Include='Service1.Designer.cs']", $nsmgr)
$oldServiceDesignerFile.SelectSingleNode("..").RemoveChild($oldServiceDesignerFile)

#save the changes.
$xml.Save($project.FullName)

无耻的自我堵塞：I'll do a full write up of the solution and issues I encountered on my blog cianm.com 希望这能节省一些人的时间。

我认为更简单的方法（可能更多支持）是通过指向DTE项目的$project变量。

注意：一年后我会进入这个阶段，但面临类似的问题。我找到了这个答案并开始使用它，但是我在PowerShell脚本末尾的Save调用时遇到了问题 - 如果我安装了一个依赖于PowerShell脚本的软件包，那么保存调用会“破坏”所以其他软件包无法正确安装。无论如何，我现在正在使用NuGet 2.5，但是自从VS 2003以来DTE没有任何重大改变，所以即使在你使用的旧版NuGet中也应如此。

param($installPath, $toolsPath, $package, $project)

# Selections of items in the project are done with Where-Object rather than
# direct access into the ProjectItems collection because if the object is
# moved or doesn't exist then Where-Object will give us a null response rather
# than the error that DTE will give us.

# The Service.cs will show with a sub-item if it's already got the designer
# file set. In the package upgrade scenario, you don't want to re-set all
# this, so skip it if it's set.
$service = $project.ProjectItems | Where-Object { $_.Properties.Item("Filename").Value -eq "Service.cs" -and  $_.ProjectItems.Count -eq 0 }

if($service -eq $null)
{
    # Upgrade scenario - user has moved/removed the Service.cs
    # or it already has the sub-items set.
    return
}

$designer = $project.ProjectItems | Where-Object { $_.Properties.Item("Filename").Value -eq "Service.Designer.cs" }

if($designer -eq $null)
{
    # Upgrade scenario - user has moved/removed the Service.Desginer.cs.
    return
}

# Here's where you set the designer to be a dependent file of
# the primary code file.
$service.ProjectItems.AddFromFile($designer.Properties.Item("FullPath").Value)

希望这有助于未来的人们寻求完成类似的事情。这样做可以避免依赖软件包安装失败的问题，因为项目是在软件包安装过程中保存的。

这是一个使用Build.Evaluation的简短示例，它是Visual Studio 2010 +

的一部分

$buildProject = @([Microsoft.Build.Evaluation.ProjectCollection]::GlobalProjectCollection.GetLoadedProjects($project.FullName))[0]


$toEdit = $buildProject.Xml.Items | where-object { $_.Include -eq "Service.Designer.cs" }
$toEdit.AddMetaData("DependentUpon", "Service.cs")
# ... for the other files

$project.Save()
