我正在创建一个NuGet包，并且在安装包时会将.targets文件安装到目标.csproj文件中。这可以完美地按预期工作，.targets文件具有目标元素，该元素在Build和TransformOnBuild目标之前执行。
但是，我现在要做的是在安装软件包后执行此目标。也就是说，我不希望用户在安装我的包后必须手动构建他们的.csproj。我希望软件包安装在将软件包安装到目标项目后运行此定义的目标。
原因是目标会自动生成目标项目中的一些文件（并且基于目标项目中的属性），我希望使用初始数据生成这些文件在安装时，不要等到用户构建该项目以创建数据。
FWIW，我发现的最接近这个的问题就是这个：Configure NuGet package to add a build event when installed，但这是针对构建管道的。我想在NuGet项目安装后启动构建（我的目标在.targets文件中）。

感谢@ matt-ward我能够获得最终答案。我在这里分享完整的答案。它以递归方式遍历项目以查找任何.tt文件，并将其自定义工具设置为空白，然后编译项目以生成所需的工件。这是完整的install.ps1：
# Runs every time a package is installed in a project
param($installPath, $toolsPath, $package, $project)
# $installPath is the path to the folder where the package is installed.
# $toolsPath is the path to the tools directory in the folder where the package is installed.
# $package is a reference to the package object.
# $project is a reference to the project the package was installed to.
function AdjustCustomTool( $folder )
{
foreach ( $i in $folder.ProjectItems )
{
switch ( $i.Kind )
{
"{6BB5F8EF-4483-11D3-8BCF-00C04F8EC28C}" # Folder
{
AdjustCustomTool( $i );
break;
}
"{6BB5F8EE-4483-11D3-8BCF-00C04F8EC28C}" # File
{
switch ( [System.IO.Path]::GetExtension( $i.Name ) )
{
".tt"
{
$i.Properties.Item("CustomTool").Value = "";
break;
}
}
}
}
}
}
$templates = $project.ProjectItems.Item( "DragonSpark.Templates" );
AdjustCustomTool( $templates );
# Need to load MSBuild assembly if it's not loaded yet.
Add-Type -AssemblyName 'Microsoft.Build, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'
# Grab the loaded MSBuild project for the project
$project = [Microsoft.Build.Evaluation.ProjectCollection]::GlobalProjectCollection.GetLoadedProjects($project.FullName) | Select-Object -First 1
$project.Build( "GenerateTemplateReferences" );
FWIW，这是我的.targets文件：
<Error Condition="'@(TargetReferenceFile -> Count())' == 0" Text="No DragonSpark.Templates\Generated\References.tt file found" />
<Error Condition="'@(IncludesFile -> Count())' == 0" Text="No DragonSpark.Templates\Generated\Includes.tt file found" />

答案 0 :(得分：0)
您可以使用PowerShell脚本（install.ps1）在安装NuGet包后运行构建。
PowerShell脚本可以使用Visual Studio API进行构建。类似于以下内容的东西将构建项目：
param($installPath, $toolsPath, $package, $project)
$config = $dte.Solution.SolutionBuild.ActiveConfiguration.Name
$dte.Solution.SolutionBuild.BuildProject($config, $project.UniqueName, $false)
构建特定的MSBuild目标更加棘手。你可以直接调用MSBuild.exe。这是PostSharp NuGet package所做的事情。或者您可以使用MSBuild API来构建特定目标。类似的东西：
Add-Type -AssemblyName 'Microsoft.Build, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'
# Grab the loaded MSBuild project for the project
$buildProject = [Microsoft.Build.Evaluation.ProjectCollection]::GlobalProjectCollection.GetLoadedProjects($project.FullName) | Select-Object -First 1
$buildProject.Build("YourTargetName")
请注意，我尚未测试这些PowerShell脚本。它们旨在为您提供指向正确实现的指针。
