我在Visual Studio 2012中有一个解决方案，其中包含几个项目。我试图将一个项目添加到另一个项目作为引用，以便能够一起使用它们，但我无法弄清楚为什么添加此项目引用会导致在部署/运行时出现缺少DLL的问题（下面是）。我以前使用过这种方法而没有这个问题，所以我肯定在这里漏掉了什么......
解决方案配置：
主项目：Bootstrapper
子项目：BootstrapperCustom
我试图将其作为引用添加到BootstrapperCustom的项目：LicenseCheck
部署时缺少的DLL：LicenseCheck.dll

注意: 当我重新构建BootstrapperCustom项目时，我确实看到Bootstrapper\bin\Debug中生成了LicenseCheck.dll。
