MEF load plugin from directory

Question

I work with MEF and I am looking how to change the url of the location of plugins by another means that MEF find the plugins, I want to change this line

Assembly.LoadFrom(@"C:\julia\project\project.Plugin.Nav\bin\Debug\NavPlugin.dll")));

I want to delete this url because I need to deploy my application in another machine

This is my function :

public void AssembleCalculatorComponents()
{
   try
   {
       //var catalog = new AssemblyCatalog(Assembly.GetExecutingAssembly());
       //var container = new CompositionContainer(catalog);
       //container.ComposeParts(this);
       var catalog = new AggregateCatalog();

       catalog.Catalogs.Add(new AssemblyCatalog(Assembly.LoadFrom(@"C:\yosra\project\project.Plugin.Nav\bin\Debug\NavPlugin.dll")));
       var container = new CompositionContainer(catalog);

       container.ComposeParts(this);
    }
    catch (Exception ex)
    {
       throw ex;
    }
 }

Can you please help me?

Thanks

Hello again and thanks for your response, so my problem was to load the plugin directly, so i create a directory and i place my plugins in this folder, so i find this solution

public void AssembleCalculatorComponents()
        {


            string path = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "Plugins");
            Console.WriteLine(path);
            //Check the directory exists
            if (!Directory.Exists(path))
            {
                Directory.CreateDirectory(path);
            }
            Console.WriteLine(path);
            string assemblyName = Assembly.GetEntryAssembly().FullName;
            Console.WriteLine(assemblyName);
            //Create an assembly catalog of the assemblies with exports
            var catalog = new AggregateCatalog(
                new AssemblyCatalog(Assembly.GetExecutingAssembly().Location),
                new AssemblyCatalog(Assembly.Load(assemblyName)),
                new DirectoryCatalog(path, "*.dll"));

            //Create a composition container
            var container = new CompositionContainer(catalog);
            container.ComposeParts(this);

this is my solution , thinks for all
