Visual Studio 2022的文档解释说:

Choose Build or Build Solution, or press Ctrl+Shift+B, to compile only those project files and components that have changed since the most recent build. The Build command becomes Build Solution when a solution includes more than one project. Choose Rebuild Solution to "clean" the solution and then build all project files and components. Choose Clean Solution to delete any intermediate and output files. With only the project and component files left, new instances of the intermediate and output files can then be built.

在这篇博客文章中，作者链接了对这个问题的评论:

其实不! !它们是不平等的。 不同之处在于项目从清洁到构建的顺序。让 假设我们在一个解决方案中有两个项目。清洁，然后建立意志 对两个项目执行clean，然后将单独进行构建 而在重建时，项目A将获得和清洁，然后再建造 项目B将会是干净的，然后建造等等。

重建=清洁+构建(通常)

值得注意的细节:

For a multi-project solution, "rebuild solution" does a "clean" followed by a "build" for each project (possibly in parallel). Whereas a "clean solution" followed by a "build solution" first cleans all projects (possibly in parallel) and then builds all projects (possibly in parallel). This difference in sequencing of events can become significant when inter-project dependencies come into play. All three actions correspond to MSBuild targets. So a project can override the Rebuild action to do something completely different.

另一个不同之处是:Clean会清除测试资源管理器中的测试结果，而Rebuild不会。

让我们根据默认的Clean和Build实现来定义默认的Rebuild实现:

每个项目:重建项目=清理项目+构建项目。 每个解决方案:重建sln = sln中的foreach项目(清洁项目+构建项目)。

注意，由于执行顺序的不同，重建sln与(Clean sln + Build sln) = (sln Clean项目中的foreach项目)+ (sln Build项目中的foreach项目)并不相同。此外，这个“foreach”可以并发执行，因此不同的任务可以在两种场景中并发运行。

假设您有一个包含proj1、proj2和proj3的sln。

Rebuild sln = （Clean proj1 + Build proj1） & （Clean proj2 + Build proj2） & （Clean proj3 + Build proj3） Clean Sln + Build Sln = （Clean proj1 & Clean proj2 & Clean proj3） + （Build proj1 & Build proj2 & Build proj3）

+表示连续，&表示并发。

因此，如果项目依赖项没有正确配置，那么在执行Rebuild sln时，可能会有一些项目链接到一个过时的库。这是因为不能保证在第一次构建开始之前完成所有清理。如果你执行Clean sln + Build sln，他们会给出一个链接错误，并立即让你知道，而不是给你一个有奇怪行为的应用程序。
