Importing into a Exported object with MEF
- by Nathan W
I'm sorry if this question has already been asked 100 times, but I'm really struggling to get it to work.
Say I have have three projects.
Core.dll
Has common interfaces
Shell.exe
Loads all modules in assembly folder.
References Core.dll
ModuleA.dll
Exports Name, Version of module.
References Core.dll
Shell.exe has a [Export] that contains an single instance of a third party application that I need to inject into all loaded modules.
So far the code that I have in Shell.exe is:
static void Main(string[] args)
{
ThirdPartyApp map = new ThirdPartyApp();
var ad = new AssemblyCatalog(Assembly.GetExecutingAssembly());
var dircatalog = new DirectoryCatalog(".");
var a = new AggregateCatalog(dircatalog, ad);
// Not to sure what to do here.
}
class Test
{
[Export(typeof(ThirdPartyApp))]
public ThirdPartyApp Instance { get; set; }
[Import(typeof(IModule))]
public IModule Module { get; set; }
}
I need to create a instance of Test, and load Instance with map from the Main method then load the Module from ModuleA.dll that is in the executing directory then [Import] Instance into the loaded module.
In ModuleA I have a class like this:
[Export(IModule)]
class Module : IModule
{
[Import(ThirdPartyApp)]
public ThirdPartyApp Instance {get;set;}
}
I know I'm half way there I just don't know how to put it all together, mainly with loading up test with a instance of map from Main.
Could anyone help me with this.
