wix - wix customaction 与 Publish Event="DoAction" 一起使用时会出现错误 2896

问题描述

wxs 文件


<Dialog Id="InputParameters" Width="370" Height="270" Title="!(ll.MyDlg_Title)">
        <Control Id="Next" Type="PushButton" X="236" Y="243" Width="56" Height="17" Default="yes" Text="!(loc.WixUINext)" >
          <Publish Event="DoAction" Value="ValidateParameters" >1</Publish>   
        </Control>
 <Dialogue>

<CustomAction Id="ValidateParameters" BinaryKey="my_dll.CA.dll" DllEntry="ValidateParametersFunc" Execute="immediate" />

CustomAction.cs 文件

[CustomAction]
public static ActionResult ValidateParametersFunc(Session session) 
{
     session.log("perform validation");
     return ActionResult.Success;
}

CustomAction.config

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <startup useLegacyV2RuntimeActivationPolicy="true">
        <supportedRuntime version="v4.0" />
        <supportedRuntime version="v2.0.50727"/>
<configuration>

当用户单击 InputParameters Dialogue 上的 Next 按钮时，我正在尝试执行验证功能。我的所有其他自定义操作都包含在 InstallExecuteSequence 中。如果我使用 VBScript 使用以下 customAction 而不是上面的函数 ValidateParametersFunc 来显示弹出窗口，那么效果很好。

   <CustomAction Id="ValidateEnrollmentParameters" Script="vbscript" Execute="immediate"> <!CDATA[msgbox "You clicked?"]]></CustomAction>

但我想执行函数ValidateParametersFunc。我收到错误：

The installer has encountered an unexpected error installing this package. This may indicate a problem with this package. The error code is 2896. The arguments are: ValidateParametersFunc, ,

CustomActions 项目的目标框架是：v4.6.1 有人可以帮忙吗？ 我已经尝试了互联网上给出的所有内容，但仍然无法弄清楚如何解决这个问题。
