更改托管引导程序（WPF）中的属性（MSI）？

Question

A have a WPF Setup Application. I Have TextBox that binds to a Property ProductCode in my ViewModel.

How can I make the packages to be set " DEF " property in .msi project?

My code:

WPF:

 private void InstallExecute()
        {
            InstallEnabled = false;
            Bootstrapper.Engine.StringVariables["ABC"] = "zyx";
            MainWindowViewModel.PlanAction(LaunchAction.Install);
        }

Bootstrapper:

<Variable Name="ABC" bal:Overridable="yes" />

<MsiProperty Name="DEF" Value="[ABC]"/>

.MSI:

 <Property Id="DEF" />

Project with Action:

var test = session["DEF"].ToString(); //always gives empty string

You need to specify the MsiProperty like this inside your bundle:

<MsiPackage Id='MyApp' Description='My Application' SourceFile="$(var.SetupMyApp.TargetPath)">
  <MsiProperty Name="INSTALLFOLDER" Value="[MyAppInstallLocation]"/>
</MsiPackage>

Add a burn variable for it, also in the bundle:

<Variable bal:Overridable="yes" Name="MyAppInstallLocation" Value=""/>

And then

Bootstrapper.Engine.StringVariables["MyAppInstallLocation"] = "C:\MyApp";

somewhere in your bootstrapper, obviously before you start the install.
