wpf .net core win7 独立运行补丁安装记录

 Windows 7 系统上，根据 dotnet 官方文档，需要安装上 KB2533623 补丁

方案如下：

首先使用 fx 2.0 写一个启动器 如果检测可以运行则拉起.net core 主程序 否则弹出命令行提示安装补丁

using PInvoke;
using System;
using System.Diagnostics;
using System.Windows.Forms;

namespace netcorefix
{
    class Program
    {
        static void Main(string[] args)
        {
            using (var hModule = Kernel32.LoadLibrary("Kernel32.dll"))
            {
                if (!hModule.IsInvalid)
                {
                    IntPtr hFarProc = Kernel32.GetProcAddress(hModule, "AddDllDirectory");
                    if (hFarProc != IntPtr.Zero)
                    {
                        Console.WriteLine("Either running on Win8+, or KB2533623 is installed");
                    }
                    else
                    {
                        Console.Write("Likely running on Win7 or older OS, and KB2533623 is not installed");
                        Process proc = new Process();
                        proc.StartInfo.FileName = "installpack.bat";
                        proc.Start();
                        proc.WaitForExit();
                        MessageBox.Show("修补完成请重启电脑");
                    }
                }
            }

            // 以下是判断 Universal C Runtime 的逻辑，可以忽略
            using (var hModule = Kernel32.LoadLibraryEx("UCRTBASE.dll", IntPtr.Zero, Kernel32.LoadLibraryExFlags.LOAD_LIBRARY_SEARCH_SYSTEM32))
            {
                if (!hModule.IsInvalid)
                {
                    Console.WriteLine("UCRT is available - Either running on Win10+ or KB2999226 is installed");
                }
                else
                {
                    Console.WriteLine("UCRT is not available - Likely running on OS older than Win10 and KB2999226 is not installed");
                }
            }
        }
    }
}

2、创建一个bat文件将以下命令复制到bat里 补丁放在同一个目录

echo 正在安装补丁请稍后....
cd /d %~dp0
wmic qfe GET hotfixid | findstr /C:"KB2533623"
if %errorlevel% equ 0 (Echo Patch KB2533623 installed) else (
wusa Windows6.1-KB2533623-x64.msu /quiet /norestart
wusa Windows6.1-KB2533623-x86.msu /quiet /norestart
exit /b 1
)
exit /b 0
