WIX自定义操作执行失败

Question

我已经创建了一个在数据库上执行脚本的设置。但是，当我尝试运行安装程序时，我从日志中获取了以下错误。

Doing action: VerifyConnection Action 12:03:17: VerifyConnection.

有没有办法解决这个问题？

Answer 1

1. 确保您的操作具有正确的签名；尤其是方法需要是“公共的”和“静态的”，即类似于"public static ActionResult doSomething(Session )“的内容
2. 使用"CustomAction”属性标记方法，以便在处理在一个dll中实现的多个自定义操作时导出
3. ，确保您不会遇到已知的MakeSfxCA错误(参见。http://wixtoolset.org/issues/4502/或Adding a new Custom Action to a project prevents an existing Custom Action from being run)
