好问题。
我正在为我当前的项目使用 WixSharp，我对此非常满意。您可以通过使用 C# 语法来避免编写 XML 文件，这真是太棒了。顺便说一句，我不认为你是在重新发明轮子……你是在用 WixSharp 加速轮子。
由于 WixSharp 1.9.6 版不提供创建具有关联 WebAppPool 的网站，因此我通过创建 CustomWebSite.cs 文件来实现。通过这种方式，我使用以下代码创建了我的 Web 应用程序：
...
var project = new ManagedProject("My Project",
new InstallDir(@"c:\my_tool",
new Dir("my_frontend",
new Files($"{frontendDir}\\app\\*.*"),
new CustomWebSite("GateKeeper", "*:31515")
{
WebApplication = new CustomWebApplication("DemoApp")
{
WebAppPool = new WebAppPool("DemoApp", "ManagedPipelineMode=Integrated;Identity=applicationPoolIdentity"),
},
InstallWebSite = true
}
)
),
...
这是我仅用于创建一个网站的 CustomWebSite.cs 文件，我相信它会更好：

using static WixSharp.WebSite;

您还可以通过其他方法来解决您的问题，通过在WebSite definitions 之后生成 WIX xml 文件并使用WixSharp IIS Sample with XMLInjection 中指示的 XML 注入，您可以在其中订阅 WixSourceGenerated 事件。
project.WixSourceGenerated += Compiler_WixSourceGenerated;
请记住，WixSharp 会生成 Wix XML 定义文件，您可以在 WixSourceGenerated 事件之后修改此 XML 文件。
