如何加载 wpf exe 并在同一进程和应用程序域中通过反射启动它？

Question

我正在使用 TinyJitHook https://github.com/Elliesaur/TinyJitHook 来修补已编译的可执行文件。

我想加载一个wpf exe文件并在ac#控制台程序中运行它；

wpf程序是Visual Studio默认的空窗口。

主程序是控制台程序；

当我运行主程序时，出现“无法找到资源‘mainwindow.xaml’”错误。

我应该怎么办。

感谢发表“Process.Start("WpfApp1.exe")”评论的人，这会启动程序，但这似乎并没有使它们位于一个进程或AppDomain中。

mainApp

public static void Main(string[] args)
{
    string filePath = @"WpfApp1.exe";

    Assembly asm = Assembly.LoadFrom(filePath);
    MainJitHook hook = new MainJitHook(asm, IntPtr.Size == 8);
    hook.OnCompileMethod += ChangeExample;

    hook.Hook();
    try
    {
        MethodInfo method = asm.EntryPoint;
        method.Invoke(null, new object[] { });
    }
    catch (Exception extInfo)
    {
        Console.WriteLine(extInfo.ToString());
    }

    hook.Unhook();
    Console.WriteLine("DONE");
    Console.ReadKey();
}


private static unsafe void ChangeExample(MainJitHook.RawArguments args, Assembly relatedAssembly, uint methodToken, ref byte[] ilBytes1, ref byte[] ehBytes1)
{
    try
    {
        var methodBase = relatedAssembly.ManifestModule.ResolveMethod((int) methodToken);
        Console.WriteLine("###################### cur method is " + methodBase.Name + " asm fiel is " + relatedAssembly.GetName());
    } catch (Exception ex)
    {
        Console.WriteLine(ex.ToString());
    }
}

App.xaml

<Application x:Class="WpfApp1.App"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:local="clr-namespace:WpfApp1"
             StartupUri="MainWindow.xaml">
    <Application.Resources>
         
    </Application.Resources>
</Application>

MainWindow.xaml

<Window x:Class="WpfApp1.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:local="clr-namespace:WpfApp1"
        mc:Ignorable="d"
        Title="MainWindow" Height="450" Width="800">
    <Grid>
        
    </Grid>
</Window>

如果您有已编译的 WPF 应用程序可执行文件，则可以使用 Process.Start API 在单独的进程中运行它：

System.Diagnostics.Process.Start(@"WpfApp1.exe");
