为.Net Framework 4.0构建的WIX自定义操作不起作用？方法解决？

Question

我们使用的是WIX 3.5(Build Number 1811),并构建了一个使用Visual Studio 2008构建的自定义操作,并将目标框架构建为.Net 3.5.在我们使用Visual Studio 2010和目标框架作为.Net 4.0构建自定义操作之前,这曾经很好用.

WIX无法调用自定义操作,我们得到的错误是:

  SFXCA: Extracting custom action to temporary directory: C:\Windows\Installer\MSI69BD.tmp-\
    SFXCA: Binding to CLR version v2.0.50727
    Calling custom action SomeCompany.SomeProduct.InstallerPlugin!SomeCompany.SomeProduct.InstallerPlugin.XYZProductCustomAction.ABCMethod
    Error: could not load custom action class SomeCompany.SomeProduct.InstallerPlugin.XYZProductCustomAction from assembly: SomeCompany.SomeProduct.InstallerPlugin

Answer 1

只是我的两分钱:

与Ngm不同,我只需要为.NET 4.0添加supportedRuntime

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

重要:

1. 不要重命名CustomAction.config
2. 将CustomAction.config Build Action设置为Content,否则它将不起作用

Answer 2

好吧,我们终于解决了问题,我们必须设置:

useLegacyV2RuntimeActivationPolicy="true"
and
have both versions specified:
<supportedRuntime version="v2.0.50727"/>
and
<supportedRuntime version="v4.0"/>

如果只是"<supportedRuntime version="v4.0"/>指定,它不起作用.所以看起来像WIX 3.5 Beta中的一个错误
