WiX手册包括“How To: Install the .NET Framework Using Burn”。但是，这些说明似乎不适用于在 Windows 8、Windows Server 2012 和更高版本的操作系统上安装 .NET Framework 3.5。参见 this StackOverflow question特别是this wix-users mailing list discussion了解详情。 Microsoft .NET Framework 3.5 Service pack 1 (Full Package) installer不会运行，因为你需要使用 Deployment Image Servicing and Management (DISM.exe)或其他一些技术来启用所请求的框架作为 Windows 功能。建议的命令行如下，假设 Windows 安装在默认位置:

C:\Windows\system32\dism.exe /online /norestart /enable-feature /featurename:netfx3

是否有一种干净的方法来确保 .NET Framework 3.5 将安装在带有 WiX 的 Windows 8 和 Windows Server 2012 上？有什么好的方法可以在安装链中包含这样的步骤吗？

最佳答案

这是我能想到的最好的。我添加了一个片段，它可以为 Windows 8 和 Windows Server 2012 之前的操作系统安装 .NET Framework 3.5。请注意，这需要为 NETFRAMEWORK35_SP_LEVEL 定义引用 NetFxExtension。

在我的托管 Bootstrap 代码中，我在应用阶段开始时处理 Windows 8/Windows Server 2012:

model.Bootstrapper.ApplyBegin += this.ApplyBegin;

...

private void ApplyBegin(object sender, ApplyBeginEventArgs e)
{
    this.EnsureNetFramework35();
}

调用dism.exe启用.NET Framework 3.5的方法如下。一些代码引用的类，如 ProgressViewModel，不会出现在每个托管 Bootstrap 实现中，但我希望这为实现您自己的版本提供了一个有用的起点。

/// <summary>
/// Make sure we have the .NET Framework 3.5 when we're on Windows 8, Windows Server 2012, or later.
/// </summary>
private void EnsureNetFramework35()
{
    // Don't worry if we're on an older OS.  We don't need DISM.exe in that case.
    if (Environment.OSVersion.Version < new Version(6, 1) && this.root.Model.Engine.NumericVariables.Contains("NETFRAMEWORK35_SP_LEVEL"))
    {
        return;
    }

    // Don't worry if .NET Framework 3.5 is already installed.
    if (this.root.Model.Engine.NumericVariables.Contains("NETFRAMEWORK35_SP_LEVEL") &&
        this.root.Model.Engine.NumericVariables["NETFRAMEWORK35_SP_LEVEL"] >= 1)
    {
        return;
    }

    // Enable .NET Framework 3.5.
    this.root.Model.Engine.Log(LogLevel.Standard, "Enabling .NET Framework 3.5.");
    this.root.ProgressViewModel.Message = "Enabling .NET Framework 3.5.";

    // Get the path to DISM.exe.
    string windowsPath = Environment.GetFolderPath(Environment.SpecialFolder.Windows);
    string systemPath = Path.Combine(windowsPath, "System32");
    if (Environment.Is64BitOperatingSystem && !Environment.Is64BitProcess)
    {
        // For 32-bit processes on 64-bit systems, %windir%\system32 folder
        // can only be accessed by specifying %windir%\sysnative folder.
        systemPath = Path.Combine(windowsPath, "SysNative");
    }

    string dismPath = Path.Combine(systemPath, @"dism.exe");
    string arguments = "/online /enable-feature:NetFx3 /quiet /norestart";

    if (!File.Exists(dismPath))
    {
        this.root.Model.Engine.Log(LogLevel.Error, "Could not find file: " + dismPath);
        return;
    }

    this.root.Model.Engine.Log(LogLevel.Standard, dismPath + " " + arguments);
    this.root.ProgressViewModel.DetailMessage = dismPath + " " + arguments;

    Process process = new Process();
    process.StartInfo.FileName = dismPath;
    process.StartInfo.Arguments = arguments;
    process.StartInfo.UseShellExecute = false;
    process.StartInfo.CreateNoWindow = true;
    process.StartInfo.RedirectStandardOutput = true;
    process.StartInfo.RedirectStandardError = true;
    process.Start();
    process.WaitForExit();

    // Check to see if we encountered any errors.
    if (process.ExitCode == 0)
    {
        this.root.Model.Engine.Log(LogLevel.Standard, ".NET Framework 3.5 enabled.");
        this.root.ProgressViewModel.Message = ".NET Framework 3.5 enabled.";
        this.root.ProgressViewModel.DetailMessage = string.Empty;
    }
    else
    {
        this.root.Model.Engine.Log(LogLevel.Error, ".NET Framework 3.5 could not be enabled.  Exit code: " + process.ExitCode);
        this.root.ProgressViewModel.Message = ".NET Framework 3.5 could not be enabled.";
        this.root.ProgressViewModel.DetailMessage = string.Empty;
    }
}
