将自定义目标添加到项目的InitialTargets属性.

Add your custom target to the InitialTargets attribute of your project.

InitialTargets ="RunTargetAfterBuild"

InitialTargets="RunTargetAfterBuild"

您是正确的，这不会解决您的问题.但是使用AfterBuild Target，我可以复制并在.sln上获取msbuild失败

You are correct that this will not solve your issue. But using the AfterBuild Target I was able to repro and get msbuild on the .sln to fail
