C# 将Microsoft.Build.BuildEngine.Engine迁移到Microsoft.Build.Evaluation.ProjectCollection

在Microsoft将BuildEngine.Engine和BuildEngine.Project标记为已过时之后，我尝试使用Microsoft的新方案，让您从下面看到它。但是我不知道在哪里可以集成xmlprojectfile。有人知道这个问题的解决办法吗

XML项目文件内容

<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <ItemGroup>
    <ProjectToBuild Include ="myproject.csproj" />
  </ItemGroup>  
  <Target Name="Build">
    <MSBuild Projects="@(ProjectToBuild)"
      Properties="Configuration=Debug" StopOnFirstFailure="true" />
  </Target>
</Project>

新的不工作verison

Microsoft.Build.Evaluation.ProjectCollection collection = new Microsoft.Build.Evaluation.ProjectCollection();
collection.DefaultToolsVersion = "4.0";
collection.RegisterLogger(new ConsoleLogger());
Microsoft.Build.Evaluation.Project project = new Microsoft.Build.Evaluation.Project(collection);
if (!project.Build())
{
    Console.ReadLine();
}

您还需要创建一个Microsoft.Build.Execution.BuildRequestData对象，其中包含XML项目文件和std属性（如配置和平台）的字典。然后，从代码段创建一个包含ProjectCollection对象的Microsoft.Build.Execution.BuildParameters对象，并将其传递给默认的Microsoft.Build.Execution.BuildManager

powershell伪代码：

#set build properties
$props = new-object "System.Collections.Generic.Dictionary``2[[System.String],[System.String]]"
$props.Add("Configuration",$config)
$props.Add("Platform",$platform)

#create the projectCollection
$projectCollection = new-object Microsoft.Build.Evaluation.ProjectCollection -argumentList $props,$loggers,"ConfigurationFile,Registry"
$request = new-object Microsoft.Build.Execution.BuildRequestData -argumentlist $project,$props,$null,$targets,$null

#create a BuildParameters object to hold the Project Collection
$parameters = new-object Microsoft.Build.Execution.BuildParameters -argumentlist @($projectCollection)
$parameters.MaxNodeCount = 1
$parameters.Loggers = $projectCollection.Loggers
$parameters.ToolsetDefinitionLocations = "ConfigurationFile,Registry"
$parameters.DefaultToolsVersion = $toolsVersion

#get the build manager and submit a build request with the appropriate parameters
$manager = [Microsoft.Build.Execution.BuildManager]::DefaultBuildManager 
$result = $manager.Build($parameters, $request)

缺少project.Load（xmlprojectfile）；在迁移的代码中输入一行。我想，您必须以某种方式将xmlprojectfile添加到projectcollection中。

而不是使用new关键字创建新项目：

使用以下命令：

 var project = collection.LoadProject("myproject.csproj")

// var project = new Project(collection);

 var project = collection.LoadProject("myproject.csproj")
