[英]Check if .NETCore is installed using CustomAction with Wix
如果未安装 NetCore 3.1(预览版),我想取消安装
我创建了这个 CustomAction:
using Microsoft.Deployment.WindowsInstaller;
using Microsoft.Win32;
namespace WixCustomAction
{
public class CustomActions
{
[CustomAction]
public static ActionResult CheckDotNetCore31Installed(Session session)
{
session.Log("Begin CheckDotNetCore31Installed");
RegistryKey lKey = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\dotnet\Setup\InstalledVersions\x64\sharedhost");
var version = (string)lKey.GetValue("Version");
session["DOTNETCORE31"] = version == "3.1.0-preview3.19553.2" ? "1" : "0";
return ActionResult.Success;
}
}
}
然后在 WXS 文件中:
<<?xml version="1.0" encoding="UTF-8"?>
<Wix xmlns="http://schemas.microsoft.com/wix/2006/wi"
xmlns:netfx="http://schemas.microsoft.com/wix/NetFxExtension">
<Product ...>
(...)
<Property Id="DOTNETCORE31">0</Property>
<Condition Message="You must first install the .NET Core 3.1 Runtime">
Installed OR DOTNETCORE31="1"
</Condition>
<InstallExecuteSequence>
<Custom Action="Check.NetCore" Before="LaunchConditions">NOT Installed</Custom>
</InstallExecuteSequence>
</Product>
<Fragment>
<Binary Id="WixCA.dll" SourceFile="$(var.WixCustomAction.TargetDir)$(var.WixCustomAction.TargetName).CA.dll" />
<CustomAction Id="Check.NetCore" BinaryKey="WixCA.dll" DllEntry="CheckDotNetCore31Installed" Execute="immediate" />
</Fragment>
这就是我遇到问题的地方,因为我总是收到警告信息。 一个主意? 谢谢
调试:您是否将调试器附加到您的自定义操作,以便您可以看到那里发生了什么? 我敢打赌,它没有正确设置您的财产。
The custom action might not be running at all
? 显示一个消息框来冒烟测试一下? 更多参与(附加 Visual Studio 调试器):
调试时回答(如果不使用附加的调试器,请略过)
请参阅此处的调试部分(更全面,更多链接)
LaunchCondition :在 MSI 数据库中,启动条件由LaunchCondition 表中的记录表示。 该表有两列。 Condition 列包含一个表达式,该表达式必须计算为True才能继续安装:
结论:
So your condition does not evaluate to true properly
。DOTNETCORE31
的实际值是多少? 我敢打赌它是0
。 请仔细检查。 最简单的方法显然是直接将其设置为1
而不是0
- 然后再次编译并测试。 硬编码暂时像这样:<Property Id="DOTNETCORE31">1</Property>
链接:以下是有关启动条件和其他主题的一些先前答案:
minimal dependencies
和debugability
- 它运行本机,没有层,仿真和可能破坏的东西) WiX 自定义操作:您有调用自定义操作的基本标记吗? 使用Orca
检查编译的 MSI 以查看Binary
、 CustomAction
和InstallExecuteSequence
和InstallUISequence
表中是否有条目。 一些模型 WiX 标记( 用于样品的掠夺 gihub.com? ):
<Binary Id="CustomActions" SourceFile="C:\Test.CA.dll" />
<...>
<CustomAction Id="CustomAction1" BinaryKey="CustomActions" DllEntry="CustomAction1"/>
<...>
<InstallUISequence>
<Custom Action="CustomAction1" After="CostFinalize" />
</InstallUISequence>
<...>
<InstallExecuteSequence>
<Custom Action="CustomAction1" After="CostFinalize" />
</InstallExecuteSequence>
GUI 和静默安装:显然,您也可以从对话框事件中运行自定义操作——比如单击按钮——但这会使它不会在静默模式下运行。 GUI 在静默模式下被跳过,因此您需要在InstallExecuteSequence
和 GUI 中运行自定义操作。
也许最好使用带有dotnet --version
命令的 cmd 检查 .net 核心版本,以避免 windows 架构依赖性
此案例的自定义操作示例:
[CustomAction]
public static ActionResult CheckVersion(Session session)
{
var minVersion = new Version(3, 1, 1);
var command = "/c dotnet --version";// /c is important here
var output = string.Empty;
using (var p = new Process())
{
p.StartInfo = new ProcessStartInfo()
{
FileName = "cmd.exe",
Arguments = command,
UseShellExecute = false,
RedirectStandardError = true,
RedirectStandardOutput = true,
CreateNoWindow = true,
};
p.Start();
while (!p.StandardOutput.EndOfStream)
{
output += $"{p.StandardOutput.ReadLine()}{Environment.NewLine}";
}
p.WaitForExit();
if (p.ExitCode != 0)
{
session["DOTNETCORE1"] = "0";
return ActionResult.Success;
//throw new Exception($"{p.ExitCode}:{ p.StandardError.ReadToEnd()}");
}
//you can implement here your own comparing algorithm
//mine will not work with -perview string, but in this case you can just
//replace all alphabetical symbols with . using regex, for example
var currentVersion = Version.Parse(output);
session["DOTNETCORE1"] = (currentVersion < minVersion) ? "0" : "1";
return ActionResult.Success;
}
更新:正如亚当所提到的,我错了那个片段 - 它只适用于 SDK。 这是另一个获得运行时的方法:
static readonly List<string> runtimes = new List<string>()
{
"Microsoft.NETCore.App",//.NET Runtime
"Microsoft.AspNetCore.App",//ASP.NET Core Runtime
"Microsoft.WindowsDesktop.App",//.NET Desktop Runtime
};
[CustomAction]
public static ActionResult CheckVersion(Session session)
{
var minVersion = new Version(3, 1, 1);
var command = "/c dotnet --list-runtimes";// /c is important here
var output = string.Empty;
using (var p = new Process())
{
p.StartInfo = new ProcessStartInfo()
{
FileName = "cmd.exe",
Arguments = command,
UseShellExecute = false,
RedirectStandardError = true,
RedirectStandardOutput = true,
CreateNoWindow = true,
};
p.Start();
while (!p.StandardOutput.EndOfStream)
{
output += $"{p.StandardOutput.ReadLine()}{Environment.NewLine}";
}
p.WaitForExit();
if (p.ExitCode != 0)
{
session["DOTNETCORE1"] = "0";
return ActionResult.Success;
//throw new Exception($"{p.ExitCode}:{ p.StandardError.ReadToEnd()}");
}
session["DOTNETCORE1"] = (GetLatestVersionOfRuntime(runtimes[0], output) < minVersion) ? "0" : "1";
return ActionResult.Success;
}
}
private static Version GetLatestVersionOfRuntime(string runtime, string runtimesList)
{
var latestLine = runtimesList.Split(Environment.NewLine).ToList().Where(x => x.Contains(runtime)).OrderBy(x => x).LastOrDefault();
if (latestLine != null)
{
Regex pattern = new Regex(@"\d+(\.\d+)+");
Match m = pattern.Match(latestLine);
string versionValue = m.Value;
if (Version.TryParse(versionValue, out var version))
{
return version;
}
}
return null;
}
在Stein Asmul的帮助下,我能够调试我的 CustomAction。 这是有效的代码:
using Microsoft.Deployment.WindowsInstaller;
using Microsoft.Win32;
namespace WixCustomAction
{
public class CustomActions
{
[CustomAction]
public static ActionResult CheckDotNetCore31Installed(Session session)
{
session.Log("Begin CheckDotNetCore31Installed");
RegistryKey localMachine64 = RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, RegistryView.Registry64);
RegistryKey lKey = localMachine64.OpenSubKey(@"SOFTWARE\dotnet\Setup\InstalledVersions\x64\sharedhost\", false);
var version = (string)lKey.GetValue("Version");
session["DOTNETCORE1"] = version == "3.1.0-preview3.19553.2" ? "1" : "0";
return ActionResult.Success;
}
}
}
