这是我能想到的最好方案。我添加了一个片段,可以在Windows 8和Windows Server 2012之前的操作系统上安装.NET Framework 3.5。请注意,这需要引用NetFxExtension来定义NETFRAMEWORK35_SP_LEVEL。

在我的托管引导程序代码中,我正在处理应用阶段开始时的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。一些代码引用了像
ProgressViewModel
这样的类,这些类可能不在每个托管的启动程序实现中,但我希望这为实现自己版本提供了一个有用的起点。
private void EnsureNetFramework35()
{
if (Environment.OSVersion.Version < new Version(6, 1) && this.root.Model.Engine.NumericVariables.Contains("NETFRAMEWORK35_SP_LEVEL"))
{
return;
}
if (this.root.Model.Engine.NumericVariables.Contains("NETFRAMEWORK35_SP_LEVEL") &&
this.root.Model.Engine.NumericVariables["NETFRAMEWORK35_SP_LEVEL"] >= 1)
{
return;
}
this.root.Model.Engine.Log(LogLevel.Standard, "Enabling .NET Framework 3.5.");
this.root.ProgressViewModel.Message = "Enabling .NET Framework 3.5.";
string windowsPath = Environment.GetFolderPath(Environment.SpecialFolder.Windows);
string systemPath = Path.Combine(windowsPath, "System32");
if (Environment.Is64BitOperatingSystem && !Environment.Is64BitProcess)
{
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();
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;
}
}
