解决Unity3D 创建UWP应用出现Exception: Failed to build Visual Studio project using arguments

解决方案在下方

本人在使用Unity3D生成UWP的时候遇到了如下的报错：

这个只是我个人遇到的错误，其他人的报错可能有所出入，但是都是在Unity3D生成UWP应用时产生的。验证是否是本问题的方法是查看是否有/fwlink/?LinkID=241478这个链接出现。

如果你真的进这个链接看了，并且尝试重做了，八成还是会失败的。因为问题很少是由于证书过期造成的，毕竟各位也不是傻子，都会看一下publish的参数。

问题其实也不在于是否在本地安装证书。

问题在于，不能设置密码！！！

没错，其实问题就在于证书的密码要为空。不要以为在导入的时候输入密码就可以了，实际上是不！可！以！的！

当你重新生成一个没有密码的测试证书后，你会发现，丫的不报错了。

我花了一个晚上+一个下午的时间研究，总计花了超过8个小时才发现这个问题。希望能解决大家的问题，不要在这个破BUG上耽搁时间了。

至于我怎么发现的，并不是偶然尝试无密码。而是在VS下编译的时候给出的提示。这个提示在Unity里是没有的，也没有几个人会去把Unity生成的工程再打开自己检查。。。

谢谢大家
