AppDomain.Load() fails with FileNotFoundException

Question

I\'m trying to load my plugin dll into separate AppDomain, but Load() method fails with FileNotFoundException. Moreover, it seems like setting PrivateBinPath property of AppDoma

Thanks a lot to DedPicto and James Thurley ; I was able to implement a complete solution, I posted in this post.

I had the same problem as Emil Badh : if you try to return from "Loader" class an interface that represents a concrete class that is unknown in current AppDomain, you get a "Serialization Exception".

It is because the concrete type tries to be deserialized. The solution: I was able to return from "Loader" class a concrete type of a "custom proxy" and it works. See referenced post for details :

// Our CUSTOM PROXY: the concrete type which will be known from main App
[Serializable]
public class ServerBaseProxy : MarshalByRefObject, IServerBase
{
    private IServerBase _hostedServer;

    /// 

    /// cstor with no parameters for deserialization
    /// 
    public ServerBaseProxy ()
    {

    }

    /// 

    /// Internal constructor to use when you write "new ServerBaseProxy"
    /// 
    /// 
    public ServerBaseProxy(IServerBase hostedServer)
    {
        _hostedServer = hostedServer;
    }      

    public string Execute(Query q)
    {
        return(_hostedServer.Execute(q));
    }

}

This proxy could be returned and use as if it was the real concrete type !
