在上一篇中曾留下两个问题，.Net捆绑安装不触发以及路径选择的问题现在都已经解决，这段时间花的最多的地方还是WPF调样式上面，奈何WPF功力不够，暂时还是没有达到自己想要的效果。另外ViewModel做了些调整，状态更加分明。安装效果是仿照搜狗输入法做的。先上效果图。
以上这只是四个基本的页面，更细化一些可以分出卸载的进度页面，卸载的完成页面，对修复同理，还有安装失败，用户取消提示页面,再就是能检测新版本并覆盖安装，这些都可以根据状态去添加页面。下面简单的说下思路和新的问题点。
关键流程
安装包运行之后，首先触发的重要的事件之一就是 DetectPackageComplete，Bootstrapper按照Bundle.wxs Chain里面Package的顺序来检测当前电脑是否安装了其中的程序。
<Chain DisableRollback='yes'>
<PackageGroupRef Id="Netfx4Full" />
<MsiPackage Id="HeartBeats" SourceFile="D:\SetUp\Main\TestWix\bin\Debug\zh-cn\WPFDemo.msi" Compressed="yes" DisplayInternalUI="no" >
<MsiProperty Name="INSTALLFOLDER" Value="[InstallFolder]"/>
MsiPackage>
Chain>
像这样，首先会判断是否安装了.Net4.0，但是在WPF程序里面我们需要判断的还是HeartBeats这个安装包。·
protected void DetectPackageComplete(object sender, DetectPackageCompleteEventArgs e)
{
PackageId = e.PackageId;
//对应的是MsiPackage Id="HeartBeats"
//MessageBox.Show(e.PackageId + e.State);
if (e.PackageId.Equals("HeartBeats", StringComparison.Ordinal))
{
State = e.State == PackageState.Present ? InstallState.Present : InstallState.NotPresent;
//State = InstallState.NotPresent;
}
}
如果这个安装包的State等于 PackageState.Present 那说明当前电脑已经安装过了，那就要出现卸载和修复的界面，反之就是出现安装的界面(因此也可以控制用户不能直接卸载，可以让用户提交一些数据之后再卸载)。然后会执行PlanBegin->PlanComplete->
ApplyBegin->ApplyComplete. 从字面意思理解就是安装准备到执行完毕的过程。InstallState的值就是在这些事件中发生变化，这也是从进度条页面切换到完成页面的顺序。InstallState 为Applied就是安装完成了。
public enum InstallState
{
Initializing,
Present,
NotPresent,
Applying,
Cancelled,
Applied,
Failed,
}
其他的一些细节在前文里面有讲，这里就不再赘述。
安装界面布局
这里的布局主要是四个Grid根据状态不断的切换。当然你可以添加更多的状态也展示不同的页面。
