我想分析和调整我们的构建,希望在这里和那里节省几秒钟。我能够创建一个派生自 ResolveAssemblyReferences 的任务并改用它,但我在理解以下内容时遇到了问题(来自 Microsoft.Common.targets):
<!--
============================================================
ResolveProjectReferences
Build referenced projects:
[IN]
@(NonVCProjectReference) - The list of non-VC project references.
[OUT]
@(_ResolvedProjectReferencePaths) - Paths to referenced projects.
============================================================
-->
<Target
Name="ResolveProjectReferences"
DependsOnTargets="SplitProjectReferencesByType;_SplitProjectReferencesByFileExistence">
<!--
When building this project from the IDE or when building a .SLN from the command-line,
just gather the referenced build outputs. The code that builds the .SLN will already have
built the project, so there's no need to do it again here.
The ContinueOnError setting is here so that, during project load, as
much information as possible will be passed to the compilers.

The $(ProjectReferenceBuildTargets) will normally be blank so that the project's default
target is used during a P2P reference. However if a custom build process requires that
the referenced project has a different target to build it can be specified.

</Target>
一些参数被传递,一些参数被返回,但实际工作发生在哪里呢?msdn 上的内容不多——我找到了 Microsoft.Build.Tasks.ResolveProjectBase,但它没有多大用处。
