i have attached a  code below?

when i usedAppDomain to load execute file, AppDomain can load exeute file, but not safety for thread.

so i want to text that by MEF

could you give me sample code for me?

using System;
using System.Linq;
using System.ComponentModel.Composition;
using System.Reflection;
using System.Collections.Generic;
using SharedLibrary;

class Program
{
    [Import]
    public IEnumerable<string> Messages { get; set; }

    [Import]
    public IEnumerable<IOutputString> OutputSet { get; set; }

    [Import("OutputMessages")]
    public Action<IEnumerable<IOutputString>, IEnumerable<string>> OutputMessages { get; set; }

    public void Run()
    {
        var catalog = new AggregatingComposablePartCatalog();
          // catalog.Catalogs.Add (new DirectoryPartCatalog(@"..\..\..\ExternalMessages\bin\Debug"));
           catalog.Catalogs.Add(new DirectoryPartCatalog(@"..\..\..\ExtraMessages","*.exe",true));
           catalog.Catalogs.Add (new AttributedAssemblyPartCatalog(Assembly.GetExecutingAssembly()));
        var container = new CompositionContainer(catalog.CreateResolver());
        container.AddPart(this);
        container.Compose();


        OutputMessages(OutputSet, Messages); 
        
    }
    static void Main(string[] args)
    {
        Program p = new Program();
        p.Run();
    }
}

[Export(typeof(IOutputString))]
public class ReverseOutputter : IOutputString
{
    public void OutputByOutputType(IEnumerable<IOutputString> outputSet, IEnumerable<string> messages)
    {
        foreach (var Out in outputSet)
        {
            foreach (var s in messages)
            {
                Out.OutputString(s);
            }
        }
        Console.ReadKey();
    }

    [Export("OutputMessages")]
    public void OutputByMessage(IEnumerable<IOutputString> outputSet, IEnumerable<string> messages)
    {
        foreach (var s in messages)
        {
            foreach (var Out in outputSet)   
            {
                Out.OutputString(s);
            }
        }
        Console.ReadKey();
    }


   


    public void OutputString(string value)
    {
        var saved = Console.ForegroundColor;
        foreach (var s in value.Split().Reverse())
        {
            Console.ForegroundColor = (ConsoleColor)(s.Length % 10);
            Console.Write(s + " ");
        }
        Console.ForegroundColor = saved;
        Console.WriteLine();
    }
}


public class SimpleHello 
{
    [Export]
    public string Message
    {
        get
        {
            return "hello world!!";
        }
    }
}
public class MoreMessages
{
    [Export]
    public string FunMessage
    {
        get
        {
            return "This is getting fun!";
        }
    }
}

using System;

using System.ComponentModel.Composition;


namespace ExternalMessageExe
{
   
    class Program

Answer 1

This answer is extremely late, but you can load parts from an executable by modifying the search pattern of your DirectoryCatalog.

 

More info: http://msdn.microsoft.com/en-us/library/system.componentmodel.composition.hosting.directorycatalog.aspx

Answer 2

Yes , Try loading module by module and modify the search pattern

Answer 3

Hi, i have the same problem. I need to make a wpf application that runs another app (like the surface shell)

How do you add the export to an exe?

thx,
